Choosing a building material for your future home is not an easy task. The challenge is finding one that combines strength and good insulation performance. This article will cover projects two-story houses from foam blocks. It is this material that many builders and customers love. What does he have positive sides and what needs to be considered when designing?
Disadvantages of a foam block house
Foam blocks are very popular. And this is no accident, because they have a lot of plus. These include:
- low thermal conductivity;
- light weight;
- high speed of wall construction;
- ease of processing;
- the ability to give any shape;
- affordable price;
- significant service life;
- ease of self-styling;
- savings in construction.
Foam blocks are an innovative material that has been used in Europe for many years. His hallmark is the internal structure. In ordinary bricks, it is dense, which increases its thermal conductivity. Foam blocks are made by creating a solution inside a solution a large number bubbles. For this, special additives are used that emit carbon dioxide during reaction with water. After the gases evaporate from the bubbles, they are filled with air. A certain kind of air damper is created, which prevents the transfer of heat to the outside and the flow of cold air from the outside. The structure also explains the low weight of one block. Despite its size, an adult can easily lift it.
In this case, the load on the musculoskeletal system during construction works significantly lower than other types of material. Without the use of additional belts, you can safely erect a two-story building from foam blocks. At the same time, you do not need a grinder or other types of electric saws to process them. Everything can be done with an ordinary hacksaw. Fitting the blocks is a pleasure. A standard foam block can have a size of 30 × 30 × 60 cm. This significantly speeds up the construction of walls, compared to brick. Such a building material has a relatively low cost, if we take into account its properties. In order to sensibly weigh everything when choosing, you need to know about the disadvantages of foam blocks. Among them are the following:
- hygroscopicity;
- the complexity of transportation;
- the need for external finishing;
- the need for additional insulation;
- fragility.
Due to their porous structure, foam blocks absorb moisture well. If the stone is wet, then it completely loses its insulating properties and becomes unusable. In cases where it undergoes constant freezing and thawing processes, then it can very easily burst. That is why, after construction, it is necessary to proceed with the insulation of the building and its external decoration. When laying and plastering, it is also important to use special adhesives. One of their properties should be the ability to keep moisture out of the blocks. Be very careful when transporting. Blocks can crumble or crack on rough roads.
Step by step design
Before construction, a project of a future dwelling is necessarily created. Projects of two-story houses from foam blocks can be typical or individual. The second can be drawn up independently, but this does not exclude the need to consult with professionals.
Territory
The first step in the design will be to determine the area that can be allocated for building a house. Some projects of houses from foam blocks up to 150 m 2 can be easily placed on a small suburban area. The project must specifically indicate which territory is determined for construction, and which for gardening and horticultural work. Failure to comply with these requirements may result in a fine. By the shape of the site, you can roughly determine the size of the house. It is also worth choosing how exactly it will be located. It is better if the windows of the living room, hall and other main premises of the project will face south. Also, if one of the roof slopes is located on the south side, then it will be possible to mount solar panels.
It is worth considering how exactly the approach to the house from the road will be carried out. It is necessary to take into account how it will be most convenient to pull up communications to the structure. When connecting the gas main, it is sometimes allowed to use the supply pipes that the neighbors have. An important aspect of the design will be the protection of the territory. It should be clearly visible from all windows.
Foundation
In order to correctly determine what type of foundation to add to the project of a foam block house, you need to find out in the relevant services at what level groundwater... In addition, it is necessary to find out to what depth freezing occurs in winter and whether there is heaving soils... If it became known that the groundwater is less than 2 meters, then the ideal option would be a bulk slab foundation... At the same time, it is important to carry out its high-quality reinforcement so that it can withstand the weight of the structure. When the depth of the groundwater exceeds 3 meters, then you can freely equip an ordinary strip deepened foundation.
For houses made of foam blocks, it is not recommended to use columnar or pile foundations... This is due to the need for a monolithic support. Since the blocks themselves do not have sufficient strength, they cannot support the weight of a two-story building. It is better to consult with professionals who will tell you the best foundation sizes for a specific project of a foam block house.
Advice! If you want to build a basement or cellar under a two-story house made of foam blocks, you need to take care of the basement level insulation and the construction of an insulated blind area.
Walls
Building walls from foam blocks requires some skill, which is acquired in the course of the work. The main condition will be the observance of the horizontal and vertical level of the foam block wall during masonry and the dimensions according to the project. Due to the large size of the foam blocks, flaws will be visible immediately and it is more difficult to fix them than for brick wall... To simplify the task, beacons are used. Their role can be played by a stretched twine, which is rearranged as the foam blocks are installed. For corners, special racks are used, which can be made from rolled profiles. For laying foam blocks, special glue is used. It must be applied in a thin layer so that cold bridges do not form. Also, a metal mesh is periodically placed in the aisles, which increases the strength of the foam blocks. A video about foam block walls is below.
Roof
A roof for a two-storey building made of foam blocks can be built of any configuration and included in the project. A gable roof will not have a presentable appearance, so it is better to opt for a gable, hip or broken roof. When using the latter in your project at home from foam blocks, it will also be possible to build an attic, which will be used for guests or children. For the rafter system, it is worth choosing high quality wood. It should be well dried so that it will not be led over time. Calculation of the roof of a house made of foam blocks is one of the most difficult tasks in the project, therefore, in this regard, it is also better to consult with a professional in their field.
As a flooring that will be used for a house made of foam blocks, metal tiles or corrugated board are often chosen. If you have enough funds, there is the advantage of installing soft tiles, which will give a foam block house a special look. The roof of a house made of foam blocks needs insulation, which is taken into account in the project. With proper waterproofing, you can use stone wool... It has some vapor permeability, so moisture will not accumulate in the attic space. It will be mandatory to install an ebb system that will collect rainwater into tanks or diverted from the foundation of the house from foam blocks.
Finishing
As finishing materials for a foam block house, you can use various ready-made panels. You can add siding or a block house to the project, but it is imperative to mount insulation under them. Penoplex or mineral wool can be used, but at the same time it must be laid between waterproofing membranes. An excellent solution would be to use vinyl panels with insulation. The use of tiles or natural stone is also allowed, but the total weight of a building made of foam blocks increases, for which the foundation may not be designed. When decorating a foam block house with facing bricks, it is necessary to maintain a ventilation gap of 5 cm. This will allow moisture not to linger on the foam blocks and not destroy them.
Additional facilities
As an additional structure in the project of a foam block house, you can lay a garage. Its location according to the project can be under the foam block house itself or next to it. In this case, it is worth deciding which roof will be used on it. Its walls can also be erected from foam blocks. The roof can be made single-pitched, end-to-end to the main building from foam blocks. This will reduce costs and allow access to the garage directly from the house. At the same time, in the project, you can lay a foundation adjacent to the house. Projects of houses from foam blocks with a garage are very popular due to the availability of personal transport.
Examples of finished projects
Above is a project of a two-storey foam block house, there is no garage on this project. According to the project, the first and second floors of the house are almost identical. Each has its own bathroom, a bedroom for one person and a wardrobe. On the second floor of this project of a foam block house, the area, which on the first is used as a kitchen and living room, is divided into two bedrooms. Such a project implies the possibility of living a large family or a family that loves to host guests. The entrance to the second floor is provided from the hallway, so a minimum of usable space is lost. The overall dimensions of the project are 9x9 meters.
Next project two-story house from foam blocks has large dimensions compared to the previous one. This project provides for the presence of a terrace, where it is pleasant to spend time with the family, as well as a balcony above the bay window. It will be very easy to equip a light office in the bay window. There will be plenty of natural light throughout the day. The second floor has more spacious rooms, which were used as bedrooms according to the project.
The third sample represents projects of houses from foam blocks with a garage. As you can see, the latter adjoins directly to the main building, which simplifies its maintenance. In the backyard of the project there is a large terrace where you can place a barbecue and other accessories. A separate room is intended for the boiler, so a solid fuel can be used without much difficulty. The second floor has three bedrooms and two bathrooms. This will allow you to comfortably accommodate guests for a long time.
Summary
As you can see, projects of houses made of foam blocks remain in demand and are often used in construction. With the right approach, such a dwelling can be built in a year with a full finish or even faster. An important requirement is strict adherence to exact instructions and the purchase of quality building materials.
Recently, it has become very popular to build a house "with your own hands". This is not only beneficial, but also pleasant: it gives one more reason to be proud of yourself. And lovers of mysticism claim that such a house will have a special positive aura. But let's leave the lyrics. There are quite real advantages - you decide how to arrange the rooms in the house and, of course, you will save a lot on labor.
Foam blocks have a number of advantages over other building materials. The combination of the following characteristics makes this material universal:
- Strength.
- Environmental safety, non-toxic.
- Large dimensions for faster wall erection.
- If necessary, the material can be easily cut with a hacksaw.
- If you are considering a complex project involving combined use building materials, the foam block will come in handy, because it is easily combined with most types of building materials.
- Due to its porous structure, foam concrete has the ability to "breathe" while retaining heat. You will not freeze in winter and all year round your house will be filled with light, not stagnant air.
- Soundproofing qualities.
- Fire safety.
- Ease. Due to its low density, the material is not very heavy. This means you don't have to sweat for weeks trying to establish a heavy-duty foundation.
Project development
You should start with a plan for placing the house on the site. Determine the sunniest and most shady sides. It should be borne in mind that by providing large windows on the side of the sun, you will provide several rooms with increased illumination and warmth. Based on what financial capabilities you have, think over the dimensions of the future home. The 9x9 design is the typical, most popular option. Such dimensions make it possible to conveniently arrange rooms on the first and second floors. Below is an example of a ground floor plan.
This plan provides for the location (in the given sequence, from south to north) of a boiler room, a bathroom, a hall and a hallway or vestibule in the west wing of the first floor. The right wing is one huge room, with a conditional division (without a wall in the center) into a kitchen-dining room (southern part) and a living room (western part of the room).
In an individual project, you can include everything that your imagination craves - an attached garage, a functional basement where you can place a workshop, Personal Area, a hobby room or a whole gym. Nowadays, attics on the second floor have become very fashionable. For those who do not know, the attic is something like a residential attic, built in houses with a mansard roof. Similar to those residential structures that we are used to seeing in Hollywood films, which often show a family living in a two-story house, where the attic is almost always a teenager's room. You don't need these clichés, so you can arrange anything in the attic - a billiard room, a library, a trophy room, a room for storing a collection, if you are fond of collecting something.
In the picture below you will find another version of the first floor project, more detailed, with the elaboration of some interior elements, household items, furniture.
When developing a project, consider a few nuances:
- It is best to consult a professional architect from time to time while showing him your drawings.
- It is imperative to analyze the composition of the soil, determine the depth at which the groundwater is located; It would be nice to even ask specialists to conduct a geological examination.
- If the type of soil on your site is defined as heaving , think over the moment of warming the foundation. The soil has the peculiarity of expanding at too low temperatures, thus pressure will be applied to the foundation, which can cause cracks in the foundation and even the subsequent destruction of its individual segments.
Stages of project development
1. Calculate the thickness of the walls. Building codes it is assumed that a masonry of 10 millimeters can withstand a mass of 10 tons. Determine the weight of roofing materials, floors. Since foam concrete has high thermal insulation properties, walls 300 millimeters thick will be enough for your comfort. Walls like this won't give way brickwork in strength and at the same time surpass it in terms of heat retention.
2. Get your family council together. Let everyone express their wishes for how many rooms they want to see in the new house and how they would like to arrange them. Try not to offend anyone, while taking into account the practical points: the rooms of the elderly should be on the ground floor, if you have a large family, it would not hurt to have two bathrooms, etc. Find a modern computer program on design. Having figured it out, how should you not only simplify the process of drawing up a project and calculating all the necessary quantities (the number of building materials, overall parameters, etc.), but you will also be able to arrange a real walk around your future home, having examined in detail every millimeter of what you have developed and created artificial intelligence three-dimensional space. This way you can find out if your idea will really create a comfortable home. In the picture below, you will see an example of a virtual ground floor project.
3. Carefully consider the location of windows and doorways. Be sure to mark them on the project drawing. Turn on your fantasy. Try to imagine how lighted the rooms will be, how comfortable it will be to move around them.
4. Very important point- stairs to the second floor. It can be straight or curved. The latter option will save space, which is important. It is advisable that the steps are not too high. There were mistakes that made it difficult for a young man to climb the stairs to the second floor without using his hands.
5. Select the type of roofing material. Do not forget - most of the heat leaves the house through the roof; take care of its multilayer insulation.
6. The floors must be warm. For this, you can use both traditional, familiar methods, and innovative methods, including safe electric heating.
Finishing planning
There are many options, it all depends on your financial capabilities. Often siding, tiles or facing bricks are chosen for the exterior decoration of the facade. Recently, facade plaster has been very popular. This material creates additional heat and sound insulation for the house. In interior decoration, the range of possible materials is infinitely wide - from drywall to tiles. Here you should focus on your personal taste, as well as on practicality and aesthetic appeal. Below is another version of the project and a photo. finished house.
Engineering Communication
Your project should take into account the convenient location of the water supply system, sewerage system, electricity and gas supply, ventilation ducts, in general, all the elements of communications necessary in the home of a modern person.
Landscape
The last stage is development landscape design your site. Decide on the location of utility structures. You can build a gazebo, a bathhouse, a building for livestock, define a plot for a vegetable garden and a garden. Do not forget to comply with fire and health safety standards.
Video - designing a two-story house
The growing need for housing leads to the fact that many families are settling near large cities. They acquire land for own construction or they buy ready-made houses in cottage villages. In this case, houses built - of artificially created concrete with a large-cell structure - became profitable and practical.
Project preparation
The construction of a house begins with the preparation of a project, which includes architectural and design solutions of planners and owners. A photo of houses from foam blocks will help you with this.
The main materials of the project are:
- drawings with a view of the building, made from different angles;
- schematic plans for the development of the entire territory;
- layouts of all floors of the building;
- the total area of the building, the area and number of living rooms and auxiliary premises, the presence of windows and doors, stairs;
- basic materials for foundations, walls, partitions, roofs, floors;
- engineering solutions and wiring.
Projects of two-story houses from foam blocks
An advanced modern material for wall construction, which can be of different sizes, provided that it is light in weight. Practice shows that the most popular are projects of two-story houses from foam blocks. This is due to:
- aesthetics of the design;
- saving land area;
- compactness;
- practicality and comfort.
project of a two-story house made of foam blocks
In the project of two-storey houses made of foam blocks, most often there is a kitchen, living room and utility rooms on the ground floor, and several bedrooms on the second floor. If desired, such a project can be changed or redone. The project of a two-story house made of foam blocks is economical. An effective option is the construction of walls from foam blocks, which are approximately 375-400 mm thick. This includes the thickness of the block, an air ventilation layer of 3-4 cm, capable of removing moisture from the pores. To guarantee thermal conductivity and, aesthetics and practicality, the house is faced with bricks. Between the cladding layer and the blocks, if desired, a layer of insulation is laid. Such capital structure will serve more than one generation of residents.
A more economical option is the construction of load-bearing walls made of foam concrete with a further coating of facade plaster. In this case, mineral wool or another type of insulation can serve as a heater. Photos of houses made of foam blocks with brick or plaster facing are available on the construction portal on the Internet.
Looking at the numerous photos of houses made of foam blocks, you involuntarily fall in love with beautiful and spectacular buildings made of aerated concrete. Houses of 2 floors are especially beautiful and surprisingly compact. On a small square there is a building of an unusual shape with a terrace, spiers, and lanterns. Such arrangement gives the house an amazing and original look. Downstairs there is a parking cover. One-story foam block houses, faced with silicate brick... In this case, without knowing the composition of the walls, it can be assumed that the structure was erected from a different material.
The practicality of aerated concrete houses
Aerated concrete houses are considered very warm and comfortable. Foam concrete is a non-combustible material that can be processed without restrictions. It can be sawn, drilled, milled, made arches, cut holes for sockets, electrical wiring, pipes. This material has durability, in many of its characteristics, it resembles wood. The foam is very lightweight and won't even sink in water. Therefore, the walls of houses made of foam concrete have lightness that does not require massive and heavy foundations. Due to the cellular structure, houses of their foam blocks absorb noise well and retain heat. The main practicality of aerated concrete is its speed of construction.
When the site does not please with spaciousness and ideal landscape, but you want to put a large house made of foam concrete on it, you will have to abandon low buildings in favor of two-story buildings. In terms of construction, they are a little more complicated and often come at a higher price, but it is much more convenient to live in them with your family. Suitable project at home you can choose among many typical options for foam blocks or order individual development... The main thing is to make a competent calculation of the materials.
To determine whether it is worth building from foam concrete blocks at all two-storey house, you will have to consider such a project taking into account several parameters:
- Convenience and comfort.
Some family members may not be able to climb stairs. But the fact that everyone living here will have their own personal space is a definite plus. There will be a place on the site itself for the design and construction of auxiliary buildings from the same foam blocks.
- Conducting construction work.
If you have chosen lightweight foam concrete blocks as the main material, there will be no particular difficulties. They do not need an expensive and powerful foundation, and the masonry will grow very quickly. The marking of the territory for such a project will not take much time, and it will be quite easy to find or prepare a relatively flat piece of land.
A serious disadvantage is the need for the device of interfloor ceilings. And taking into account the fact that uneven loads are contraindicated for a house made of foam blocks, the construction technology will be further complicated by the presence of armored belts at each level. On the other hand, your project will halve the roof area, which means the amount of work and material costs. However, this plus will immediately negate the need for a reliable ladder (or even more than one).
- Possibilities of planning.
A two-story house built from a foam block is easier to divide into residential and auxiliary sectors. In addition, there are many more opportunities for creating convenient layout- without long corridors and intricate passages. In the design process, it is better to immediately "relocate" the main part of services to the lower level (for example, a boiler room and a utility block) in order to simplify the communication system as much as possible. The only problem is that you will need an additional bathroom on the second floor, so here you will have to sacrifice several squares of usable space.
Description of projects from foam blocks
Project number 1.
A large house made of foam concrete of a complex layout with an attic and a garage with total area 220 m 2. Several interesting solutions have been implemented in this project. For example, in the far corner on the ground floor level, there is a 16 m2 terrace, covered by a ceiling and a balcony at the top. In addition to the main entrance, there is also a black one - from it you can get into a 5x9 m garage through a mini-boiler room.
On the plan of the first level of a foam block house, the area was divided among themselves by the common areas:
- The kitchen-dining room is almost 24 square meters in size, from where there is a single exit to the terrace.
- Living room with a second light and a staircase leading to the attic.
The entrance group is also conveniently planned: from the porch you can immediately get into a spacious hallway of 11 m 2, and from there go to the garage (also made of foam blocks), the staircase hall, which unites the living room and dining room, or to the toilet located next to the entrance to the two-story house.
In the attic there is a full-fledged four-room apartment - perhaps without a kitchen. The staircase and the opening of the second light (glazed outside to the very roof) actually divided the residential floor into two blocks. In the right wing there are 12 squares for children absolutely identical in size, on the left there is a bedroom with a wardrobe niche (22 + 5 m 2) and another room that the owners can use as an office or a creative workshop. In the center, however, there was only a corridor uniting both wings with two identical bathrooms of 5 m 2 each. An additional door in the middle of the aisle makes it possible to divide the attic floor made of a foam block with an area of 67 squares into two equal halves: "adult" and "children's".
Project number 2.
Another project of a house with an attic, but more compact. There are 90 squares for housing and ancillary services, but in addition to them there is a small terrace in the backyard of 11 m2 and a garage made of foam blocks of 19 m2. m. The first floor has a similar layout to the option discussed above, except that the living room got half of the total area.
The scheme of the entrance lobby has also changed slightly. Here, the vestibule at the porch really plays the role of a cold air cutter, which is very useful if a two-story house made of foam concrete is being built in the northern region. The door from the garage also leads here. Only through this block, according to the project, you can get into the central hall with all the transitions to the adjacent rooms: the kitchen-dining room and the living room with a rise to the second floor.
The attic accommodates only two bedrooms with an area of 9.3 and 17.4 m 2, as well as one bathroom of 5.7 m 2. Moreover, all rooms are located along the side walls made of foam blocks, so that in each there will be inclined ceilings formed by the slopes of the roof. Above the garage, after the design, there is not much free space, which can only be adapted to the attic.
Project number 3.
The project of a two-story house, built from foam block, with a long and narrow veranda in the backyard has its own flavor. Here, the largest room on the first level, the living room, is complemented by a glazed bay window. Outside, above it, there is a balcony with an exit from the upper bedroom.
A rather complicated at first glance plan of the entrance block will suit those who prefer to come and leave the house without disturbing the household. From the porch, it is easy to immediately get into the vestibule, and then into the common hall, from where the transitions lead to the stairs, to the utility room, toilet or kitchen. From here you can also go to the large living room or living room next to it.
In the under-roof space of the cottage made of foam blocks, as a result of successful design, there was a place for two bedrooms and a rather large bathroom under a pitched roof of 13.7 m 2. You can get here from the L-shaped corridor, which unites the staircase hall on the plan and exits from both rooms.
What does the construction cost depend on?
The most expensive elements houses made of foam blocks are the foundation and the box itself. The base needs a special approach, since it must "work" correctly on those soils that are on the site, and at the same time do not allow them to affect load-bearing walls... This will be one of the varieties monolithic foundation: tape or plate. The first option is suitable for “calm” soil, which does not sag under load and is not subject to winter heaving. In all other cases, a slab foundation is needed - it is more expensive, but provides a rigid foundation for fragile foam blocks.
It will not be cheap if the customer wants to acquire a basement on a site with a high level of hot water or weak soils. In this case, it will be necessary to develop a project of a combined foundation with a recessed slab and a tape brought to the surface along the entire contour. In addition, it will turn out to be so powerful that it will be possible to put not just a two-story house made of foam blocks over it, but at least a Khrushchev.
Such costs will not be justified by the presence of an additional basement underground, so it is better to put up with it and move everything that you wanted to place in the cellar to the side extension.
About half of all funds will go to the box: the purchase of materials, masonry with reinforcement and subsequent turnkey finishing. Foam concrete blocks will definitely need to be sheathed outside so that they are not saturated with moisture, and at the same time lay insulation under the hinged facade. In general, the cost of a finished house with finishing according to typical project will amount to at least 20 thousand rubles. per square. But the more complex the architecture and the layout of the rooms, the more expensive the building will be.
Turnkey construction of foam concrete with all communications connected will increase costs up to 30,000 rubles / m2, and further growth of prices will depend only on the selected finishing materials.
