Expanded clay concrete M100 is one of the options for a light mix of concrete. It consists of cement, expanded clay gravel. Additionally, soft aggregates are included to form the required technical characteristics. The advantage of the material is low weight and the ability to effectively resist open fire. It keeps heat inside the surface. B7.5 is the strength class that characterizes expanded clay concrete M100. The quality certificate contains all the necessary data to determine further construction tasks. The substance has a low price, so it is available to the average person.
The material is characterized by natural ingredients. It does not deteriorate under the influence of fire, freezing and aggressive chemicals. Properly prepared composition does not crack and contributes to the absorption of sounds in the surface. It is used for insulation of one-story houses and warehouses.
Expanded clay blocks M100 after installation do not need additional care. Key properties are retained even during long-term operation. For laying, the method of tubs and cradles is used. Thanks to this, it is possible to obtain a stable surface. It will not suffer from the negative effects of weather and external conditions.
Scope of material use
Technical characteristics of expanded clay concrete M100 allow it to be used in various fields. The material is lightweight, so it is possible to immediately transport the finished substance. The product is suitable for the construction of internal and external walls, ceilings and screeds. Expanded clay concrete is used in industry and private construction. To fix the blocks, a solution or glue is used. When using the latter option, it is possible to significantly reduce the distance between the plates. This reduces heat loss.
The M100 brand allows the coating to be used as an insulating one. It is suitable for roofs, basements, garages and various structures with agricultural purposes. The material is used for reconstruction and repair. In industry, it is used to create walls, arches, columns. However, it is not recommended to impose load-bearing loads on it. If necessary, the structure is made strong by other building materials. An integrated approach makes it possible to obtain a structure that will steadfastly resist external negative factors.
Compliance of expanded clay concrete with GOST is checked using documents confirming the passage of quality control. The supplier must have all the necessary certificates. In this case, it is allowed to conclude an agreement with him. Otherwise, it is better to refuse cooperation.
Expanded clay concrete must have a passport. It serves as the only confirmation of its quality. It includes technical specifications derived from a series of studies. Attention should be paid to the index of compressive strength, the ability to withstand frost and water. Release strength is also taken into account without fail. It is fixed at the time of transfer of the material to the customer. It will not be superfluous to check on the spot. Visual inspection will help verify that the material meets the stated specifications.
The main requirements for the parameters of expanded clay concrete are specified in GOSTs:
- 13015-2012.
- 7473-2010.
The material reaches the required strength 28 days after production. If it was received earlier, then the M100 blocks will not meet the stated criteria. The indicator will reach the optimal value only in a month. During this period, the blocks will experience a reduced throughput strength. Construction work is recommended to be carried out in the warm season. Thanks to this, it will be possible to speed up the process of complete solidification and fixation of the object.
If the submitted document does not specify a quality check, then the client has the right to file a claim with the supplier. This is given no more than 24 hours from the date of shipment of the solution. In case of wholesale delivery, the certificate is generated not for each car, but for the entire batch. The opposite may be specified in the contract. However, intermediaries rarely agree to such changes.
The certificate is obtained from a special body that is authorized to carry out examinations of all types of concrete. Other documents will be required from the supplier. The initiative to conduct an examination is mandatory. It is necessary to confirm the quality of the goods. Customers will be completely sure that they are using the material they paid for.
Specifications
The M100 brand of expanded clay concrete is suitable for the construction of utility or residential buildings. It can also be used for insulation. Builders allow the use of material for filling the floor or forming screeds. It is very popular due to its reasonable price and simple installation process. For this, it is not necessary to have special skills in conducting construction work.
Before buying a material, you should analyze its technical characteristics, which are shown in the table.
The price attracts customers, so they often opt for this material. It is in the range from 1600 to 3500 rubles. per cube m. The price directly depends on the brand of concrete, which is included in the composition.
The cooking process is simple and practically does not require special equipment. It is also possible to organize the delivery of ready-made material to the construction site. It will require the presence of special heavy equipment, which is equipped with navigators. The supplier's transportation costs will be additionally included in the cost of raw materials.
It is necessary to carefully analyze the composition of expanded clay concrete. To perform a number of construction works, the M150 brand may be the best solution. It has a number of features, advantages and disadvantages.
Compound
Expanded clay concrete M100 is a lightweight concrete, which includes clay granules. They are called expanded clay. It is possible to achieve the best technical characteristics through their foaming and high temperature treatment. The result is a durable surface. Additional features include light weight. Thanks to this, it is easy to transport even ready-to-use material.
Expanded clay concrete M100 is obtained by mixing the following components:
- Cement brand 400 - 10%.
- Quartz sand of coarse fraction - 30%.
- Expanded clay - 60%.
To obtain the necessary properties of the mixture, additional plasticizers and additives are added to it to remove accumulated air. Saponified wood resin possesses such properties. The component can be replaced with a similar one in action.
The composition is suitable for use in the following industries:
- The construction of internal or external walls in one-story houses. The material is used in the construction of outbuildings.
- Wall insulation outside. The material allows you to create comfortable conditions in rooms of any type. This saves you money on heating bills.
- Filling and floor screed. The mixture is also actively used to level the surface in garages, warehouses and other target areas.
- Formation of a solid monolithic floor or screed. They are built by pouring the required amount of mortar.
Expanded clay concrete consists of materials that regularly undergo environmental testing. The coating does not suffer from aggressive detergents. There was no deterioration in properties under the influence of precipitation or low temperatures. Due to this, the solution is used to improve sewerage wells. It can be used to create workshops in which chemicals will be produced in the future.
Expanded clay concrete is ideal for building a garage or warehouse. It will be an excellent basis for a monolithic house. The supply contract should only be concluded with a verified supplier. The price of the product is acceptable, so it is popular. The quality of the material is confirmed by a certificate. It is issued on the basis of expertise.
The choice of building material is carried out at the initial design stage of the building and is one of its most important tasks. By making this choice correctly, you can ensure not only getting a warm, comfortable and reliable home, but also significantly save both the time required to achieve the final result and the amount of financial investment.
It should be borne in mind that the correct choice of material for construction depends on many factors, ranging from the type of soil on which the building will be erected to the required temperature inside. One of the universal types of building materials for erecting walls of low-rise buildings are expanded clay concrete blocks. We will consider the pros and cons of this particular building material today.
Expanded clay blocks
Advantages and disadvantages
The main advantage of expanded clay concrete blocks is the absence of chemically harmful substances and compounds in their composition. The building material is made only from environmentally friendly components, which explains their safety for the construction of residential and public buildings. In addition, the advantages of expanded clay concrete blocks include:
light weight;
increased bending and crumbling strength;
high vapor barrier properties;
low thermal conductivity;
resistance to microorganisms, mold and fungus;
resistance to temperature extremes;
incombustibility.
The use of wall expanded clay concrete blocks allows you to build buildings in a short period of time, since the technology for working with this material is quite simple and professionals will cope with it many times faster than, for example, when using bricks. The size of the block of expanded clay concrete also affects the speed of building a house. And using in combination other types of building and finishing materials, you can give the appearance of the building individuality and originality, without spending a lot of money.
Construction of a house from expanded clay concrete blocks and bricks
Expanded clay blocks do not tolerate even not very large values of shock and dynamic loads - this is the most significant drawback of the building material. Another disadvantage is that claydite-concrete blocks do not lend themselves well to a perfectly even cut.
The process of cutting expanded clay concrete block
In the process of sawing or cutting, chips and cracks are easily formed on the edges of the block, which can ultimately affect the appearance of the structure. In particular, this must be taken into account when working with front elements that will not be additionally veneered. This is an essential argument so that when building a house from expanded clay concrete blocks, contact only those specialists who have sufficient experience in this type of work.
Construction of a house from expanded clay concrete blocks
Main characteristics
The main components of expanded clay concrete blocks are cement, crushed expanded clay and sand. Depending on which fraction of expanded clay is in the composition, that is, on its size, the strength characteristics of the blocks change. The larger the expanded clay fraction, the lower the strength of the block and its thermal conductivity.
Four different fractions of expanded clay
On our website you can find contacts of construction companies that offer the service of building houses from expanded clay concrete blocks. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".
The existing sizes of expanded clay concrete blocks are provided for by the GOST 613399 standards, in which they are divided into two main groups, namely:
188x190x390 mm - elements intended for the construction of load-bearing wall structures;
188x90x390 mm - elements intended for the construction of partitions.
Expanded clay concrete block SB - 12 (188x90x390)
Considering expanded clay concrete blocks as a building material for partitions or load-bearing walls of a house, the dimensions must be chosen appropriate for the purpose.
Expanded clay blocks are divided into front and ordinary, full-bodied and with the presence of voids. The front ones are designed to create structures that do not need additional finishing, while the ordinary ones are additionally lined with finishing material.
The division of expanded clay concrete blocks into hollow and solid ones is carried out by the presence of cavities in their structure, the purpose of which is to reduce the weight of individual elements. In addition, holes in hollow blocks increase its thermal insulation properties, but reduce strength and reliability when exposed to loads. Solid block has no holes.

It should be borne in mind that the expanded clay block dimensions may not be accurate. The permissible deviation in width, height and length is a value equal to 10 to 20 mm.
Density and strength
When choosing a building material for the construction of load-bearing walls, it is necessary to pay attention to such characteristics as density and strength. The reliability of the finished structure depends on the latter, and its heat-saving and acoustic properties depend on the density. The density of the blocks is in the range from 500 to 1800 kg / m³, while the claydite-concrete blocks weight, respectively, change from 10 to 23 kg.
In turn, the strength varies from 3.5 to 20, which corresponds to static load values ranging from 35 to 250 kg/cm². These parameters ensure the duration of the operating period of at least 60 years.
Watch the video for a simple strength test of expanded clay concrete blocks:
Frost resistance and fire resistance
The frost resistance of the building material plays an important role in the durability of the structure. It is determined empirically, during the freezing and thawing of a claydite-concrete block completely soaked with water. Currently, GOST establishes 4 main grades that differ in frost resistance, namely: F25, F35, F50 and F75.
The larger the number after the letter designation, the more cycles of freezing and thawing the expanded clay block can withstand.
The fire resistance of expanded clay concrete blocks has the highest class. If the impact of open fire on the expanded clay concrete block does not exceed 7–10 hours, then nothing will happen to it.

Pros and cons of houses made of expanded clay concrete blocks
Houses made of expanded clay concrete blocks have their advantages and disadvantages. The main positive aspects of construction and finished structures include:
financial benefit. Expenses are significantly reduced due to the low cost of the material and work with it, and since the construction of expanded clay concrete is not heavy, a reinforced foundation is not required, this also saves money.
The process of laying expanded clay concrete blocks
Warm house. Thanks to the porous block filler - expanded clay, structures made of them hold heat well.
The walls of the house made of expanded clay concrete blocks are durable, freely withstand the load of floor slabs.
Houses made of high-quality expanded clay blocks are practically not subject to shrinkage, which prevents the formation of microcracks in the walls.
The building material is environmentally friendly, which means that the scrap walls do not emit any harmful substances.
Good sound insulation in the house.
Plaster fits well on walls made of expanded clay concrete blocks.
It should be noted that the porosity of expanded clay blocks is both a plus and a minus. The building material absorbs water well, and when frost sets in, moisture crystallizes and begins to destroy the structure of the block. Therefore, houses made of expanded clay concrete blocks should be protected from moisture with facing materials.
The disadvantages can also be called the occurrence of cold bridges, which can only be reduced by thermal insulation. Cold bridges occur in the seams between individual elements.
Also, the disadvantages include the size of the block of expanded clay concrete, or rather their limited choice - there are only two of them and they differ only in width - there is no way to choose the thickness of the walls of the house.

It is also worth noting that due to the fragility of the blocks, they are an unstable base for fixing dowels and other types of fasteners. Therefore, it is necessary to choose materials for interior and exterior finishing work, guided by this condition.
Expanded clay house: a new trend in modern construction
Low-rise buildings made using expanded clay concrete blocks can be safely called a new trend in modern construction. Using this material as the main one in the construction of external walls and internal partitions, the time for performing work, their cost is significantly reduced, and the heat supply of the finished building is also simplified.
House: the first floor of the front of expanded clay concrete blocks and an attic of timber
Thanks to all the advantages, turnkey construction of expanded clay concrete blocks is much more acceptable, which means that more families will be able to afford their own private home.
Thus, choosing claydite-concrete blocks as the main material for building your house, you can count not only on the operational timing of the work, but also on their fairly reasonable cost. And this can be called one of the most weighty arguments for those who decide to move from the hustle and bustle of a noisy city closer to nature.

Conclusion
Expanded clay concrete blocks as a building material are becoming more and more popular every year. If you want to save a little, contact a construction company, where they will offer you ready-made projects for houses made of expanded clay concrete blocks or draw up a unique project based on your wishes.
Expanded clay blocks, which have long conquered the Western construction market, find adherents in our country as well. The popularity is due to the fact that the source material for the manufacture of blocks has many advantages compared to brick, gas and foam concrete. The ratio of components in expanded clay concrete directly affects its density and performance.
Expanded clay concrete is a porous composite used in block or monolithic construction. Compared to other concretes, the material has a special composition. In addition to cement and sand, expanded clay is included in the mixture - foamed baked clay. In appearance, the filler resembles crushed stone, gravel or sand - it depends on the size of the fraction. Read more about the characteristics of expanded clay blocks and reviews of developers.
Here are the main properties of the composite:
- resistance to low and high temperatures;
- anticorrosive properties;
- resistance to chemically aggressive environments;
- small specific gravity.
Due to the universal qualities, the scope is quite wide. A feature of the material is the ability to adjust the composition of the expanded clay concrete mixture depending on the required density of finished blocks, panels or ceilings.
1. Construction of low-rise walls.
Blocks, panels are formed from lightweight concrete, poured into the formwork. With a density of 1000 kg / cubic meter, it can withstand loads of at least 7 MPa. To make a cubic meter of wall blocks, you need the following composition of expanded clay concrete mixture: Portland cement (grade 400) - 0.43 tons; sand - 0.32 t; expanded clay fraction from 5 to 10 mm - 0.8 m3; water - 250-400 l. A stronger material is obtained by using river or quartz sand. If part of it is replaced with expanded clay (particle size up to 5 mm), the strength is somewhat reduced, but the walls will better accumulate and retain heat. In order for expanded clay concrete blocks to have a density of 950 kg / m3, the expanded clay grade (bulk density indicator) must be at least M400-M500.
2. Making a screed.
The composition of the screed for residential buildings is approximately as follows: 2 parts of expanded clay plus 3 parts of sand plus 1 cement per 1 water. Such proportions provide sufficient strength of the concrete layer and its rapid hardening.
3. Production of floor slabs.
By casting, light products are obtained that are resistant to moisture, durable, and retain heat well. The only negative is the fragility of the material. It can be minimized by reinforcing, increasing the proportion of cement, and reducing the size of the expanded clay fraction. The ratio of components in the solution is selected as follows: 1 part of cement M400, 3-4 - sand, 4-5 - expanded clay, 1.5 - water, plasticizing additives - according to the instructions.
Under production conditions, it is necessary to adjust the proportions of expanded clay concrete due to the use of different fractions of the filler (gravel or crushed stone). If the composition is correctly set, the same brand of expanded clay concrete can be obtained, despite the different proportions of the ingredients. In this case, the ratio of cement and water can vary from ½ to 1/1.
Types and grades of expanded clay concrete
Among the main characteristics are grade M (strength, kg/cm2) and density D (kg/m3). These are complex indicators that depend on the composition of expanded clay concrete blocks (and other products) and the fractional content of the starting materials. Each brand is used for its intended purpose:
- M50 - for pouring load-bearing walls of intra-house partitions in residential buildings;
- M75 - for the manufacture of load-bearing structures in residential and industrial buildings using monolithic technology;
- M100 - for pouring screeds;
- M150 - for the production of blocks;
- M200 - for blocks and light floors;
- M300 - for road surfaces and bridges.
Depending on the density, 3 groups of expanded clay concrete are distinguished.
1. Sandless (coarsely porous). To get it, gravel, Portland cement and water are mixed. Sand is not included. The advantage of this material is its low price, it is used to form walls, floors, ceilings in low-rise construction.
2. Porous. For the manufacture of blocks, at the same time, 3 subspecies are distinguished with different levels of density:
- heat-insulating - D400-600, used for an additional layer of wall insulation;
- heat-insulating and structural - from D700 to D1400, it is used as a heater or for laying internal walls;
- wall (structural) - D1400-2000, for various engineering structures.
3. Tight. It is characterized by a high content of cement and combines the characteristics of sandless and porous options. The cost of dense expanded clay concrete is high; it is rarely used in private construction.
There is another classification of composite material - in terms of bulk density. Based on this criterion, the following types of expanded clay concrete are distinguished:
- heavy: its bulk density is 1200-1400 kg/m3, strength is 25 MPa;
- light: a cubic meter weighs 800-1000 kg / m3, natural expanded clay with a low specific gravity is introduced into the lightweight expanded clay concrete;
- especially light: the cube weighs from 600 to 1800 kg / m3, strength - from 7.5 to 40 MPa; artificially sintered expanded clay, agloporite, ash gravel, slag pumice are used as fillers for it.
Pros and cons
Developers often decide to purchase expanded clay blocks in an effort to reduce the overall cost of construction. But will the quality of the structure deteriorate in the long term? It is time to briefly list the advantages and disadvantages of the material under consideration. In addition to the affordable price of expanded clay concrete, its advantages include:
- good body-saving characteristics - due to this, it is possible to reduce the estimated thickness of the walls (compared to brick) and reduce the pressure on the foundation (ceilings);
- vapor permeability - thanks to it, the level of humidity in the premises is regulated;
- high rates of sound insulation and noise absorption;
- a sufficient level of strength - the walls of expanded clay concrete do not experience deformations, shrinkage is minimal;
- an increase in the pace of construction - if you buy light large-sized blocks, this will help to significantly speed up the masonry process;
- environmental friendliness.
The main disadvantage of the porous composite is its low moisture resistance, which requires waterproofing. External walls, laid out or cast from expanded clay concrete, cannot be left without a facing layer for a long time, otherwise the life of the house will decrease. The material has other disadvantages:
- the need for thermal insulation - if it is neglected, cold bridges are formed through which heat leaks;
- inability to use for laying the foundation, basement, garden paths;
- walls require the laying of a powerful strip foundation - despite the relatively small specific gravity, expanded clay concrete is heavier than similar building composites.
Rates
The cost for one cube of expanded clay concrete depends on the brand of material, density, performance of products (they are corpulent and hollow). Buying blocks in bulk from the manufacturer will be cheaper than a small amount through an intermediary. To purchase a quality product, it is advisable to familiarize yourself with the certificate of conformity (it confirms that the manufacturing technology has been followed), and then find out what the cost is.
| Brand/density | Class | Price, rub/m3 |
| M50/ D800 | At 3.5 | 3100 |
| M75/ D1000 | At 5.0 | 3150 |
| M100/ D1200 | At 7.5 | 3200 |
| M150/ D1400 | At 12.5 | 3400 |
| M200/ D1600 | At 15.0 | 3500 |
Recently, the building materials market has been developing very intensively. All construction technologies are being improved and new cheap materials are being introduced that are easy to install. Another representative of such innovations may be concrete with expanded clay base. In addition to high heat and sound insulation characteristics, such concrete is effective in use in earthquake-prone areas.
Environmentally friendly expanded clay, which was the basis of a new building material, has the structure of a frozen foam. The starting material of expanded clay is foamed clay, which is subsequently fired in special furnaces. The granules obtained in this way are able to withstand quite significant loads. Having such properties, expanded clay occupies a worthy place among inexpensive and effective foam aggregates. In terms of properties, expanded clay concrete is on a par with ordinary concrete, and even leads in terms of chemical and thermal insulation characteristics.
CONSTRUCTION FEATURES OF LEAKED CONCRETE.
According to its properties, expanded clay concrete can be used in any climatic conditions. The strength of expanded clay concrete is directly dependent on its density. The material is also universal with the possibility of erecting buildings from itself, both from blocks and in the form of a monolithic fill.
Technological characteristics of expanded clay concrete allow it to be divided according to:
- brand strength: it varies from 35 to 100 kg/cm2;
- density: and it varies from 700 to 1400 kg / cm3;
- Thermal conductivity efficiency: also varies from 0.2 to 0.5 kcal / hour.
- The presence of expanded clay in the material, due to its porosity, somewhat reduces the density of expanded clay concrete by 10 - 20%.
TYPES OF LEAF CONCRETE.
At modern construction sites, expanded clay concrete grades are used: from M100 to M300. Also, according to the density of expanded clay granules, expanded clay concrete is distinguished: dense, painted and sandless.
But the most popular among builders is sandless expanded clay concrete. It is used when pouring floors, erecting walls in low-rise buildings and ceilings.
Painted expanded clay concrete is used much less frequently. In turn, it is also divided into subspecies:
- constructive: mainly used in the construction of engineering structures (industrial buildings, bridges, and others). The use of expanded clay concrete elements in such structures allows savings due to the replacement of reinforced concrete elements first.
- heat-insulating: this subspecies acts as an additional insulating material as part of building envelopes and facade decoration.
- - heat-insulating and constructive: the representative of this subspecies is painted expanded clay concrete, from which wall blocks and panels are made.
The most expensive of all types of expanded clay concrete is considered "dense". The high cost is due to the inclusion of expensive cement in its composition. Structures from this type of expanded clay concrete have a specific application: basically, elements from this material are intended for the manufacture of structural elements that can withstand heavy loads, of a direct and vibrational nature.
SPHERES OF APPLICATION OF LEAKED CONCRETE.
The main place of application of expanded clay concrete is the construction of walls. In some countries, construction is carried out only from this material. Such concrete can withstand loads up to 7 MPa, with a density of a single-layer wall panel of 1000 kg/m3.
Where high heat and sound insulation of the screed is required, expanded clay concrete has proven itself perfectly. The use of expanded clay concrete for these works reduces the cost of the construction process and reduces the drying rate of the screed and, thereby, speeds up the construction completion schedule.
The architectural features of some buildings require the use of dense expanded clay concrete. But, since expanded clay concrete itself is, in fact, a rather fragile material, it is imperative to use reinforcing components as part of floor slabs.
The wide popularity of expanded clay concrete, both in the West and now in Russia, is associated with a number of expressive advantages of this material:
- resistance of the material to temperature changes;
- the ability to maintain a long period of properties given by the manufacturer;
- ease of transportation;
- resistance to corrosion, aggressive environments, high humidity and other adverse operating conditions.
ADVANTAGES OF APPLICATION OF LEAKED CONCRETE.
In comparison with concrete, expanded clay concrete has characteristic differences. So, the latter perfectly retains heat and is therefore used mainly in cold regions.
Also, expanded clay concrete allows you to significantly save on material. It, in comparison with concrete, is consumed two times less, gives less shrinkage and is noticeably lighter than the opponent.
Possessing porosity, expanded clay concrete allows walls made of it to regulate the level of humidity in the premises. The material is unpretentious in maintenance and has absorbed most of the positive properties of brick and wood.
If we compare expanded clay concrete with a brick, then it is appropriate to note that one block of the first one replaces 7 bricks and is twice as light as them combined. The speed of building a structure from expanded clay concrete increases by 4-5 times than from brick. The cost of manufacturing a block of expanded clay concrete is much less than the cost of manufacturing that volume of bricks.
You have decided to build a country house, and do you want to use expanded clay concrete blocks as a material? Then you are probably interested in questions about their cost, size and much more.
Time does not stand still, the range of "classic material comes from the sixties" has increased markedly in recent years. This happened due to the fact that manufacturers want to stand out from their competitors.
The main problem when searching for information is that 70% of advertising messages about the sale of expanded clay concrete blocks are published by so-called outbids. Most of them contain unreliable data and distort all information about wall blocks.
To help you understand all aspects of choosing this building material, we have written this article. Today you will learn what claydite concrete blocks are. Pros and cons, reviews, projects, sizes and prices - we tried to cover the topic from all sides and we hope that the information we have collected will be useful to you.
Sizes and prices of expanded clay concrete blocks
Wall blocks are used for masonry walls, and their key indicator is strength grade, because they bear the brunt of the burden. Wall blocks are divided into:
- four-slot(from 37 rubles apiece);
- corpulent(from 59 to 66 rubles apiece);
- two-hollow(from 40 to 45 rubles apiece);
- three-hollow(from 39 to 44 rubles apiece);
- multi-slit(from 35 to 57 rubles apiece);
- (from 119 to 149 rubles apiece);
- through(from 119 to 270 rubles apiece).
Expanded clay blocks
Purpose vertical voids(or slots) is to give the material mass, density and thermal conductivity. V corpulent There are no voids in the expanded clay block, so it is much heavier and stronger than its counterparts with through and non-through holes. This type of material is used in the construction extra strong walls all types of buildings (multi-storey garage or house).
Four-slot hollow wall blocks will be a good basis for a cottage-type building and any other three-dimensional buildings.
