Estimates and projects of houses. Calculation of the construction estimate. Calculation principles for budgeting

The choice of foam blocks for building a house testifies to the developer's reasonable savings. To assess the benefits of such a solution, you should first calculate a turnkey estimate. This will help you plan for future expenses and find out if there is enough savings for the construction in the family budget. In addition, a detailed listing of materials gives an objective picture of the upcoming construction and suggests ways to save money without damaging the house.

Finishing weighs almost 40% of the total construction budget. If large jobs take a long time, the finishing part, it is, is causing the budget. This obviously depends on the taste and financial capabilities of the owner. Plastering for false ceilings will be the next stage after large works. The result is a painting whose value depends on quality, type or color. It also differs from the exterior and interior of the house.

After that, there is a step to cover the ground. The owner can choose tiles, marble or parquet according to his means and his preferences. Then comes the plumbing fixtures. The next step concerns everything related to iron and carpentry. For example, steel structures affect fencing walls, balconies, garage doors, stair ramps, main door and window protection. In addition, the iron works depending on the thickness, structure and quality of the iron used. The joinery, on the other hand, is divided into two parts, the first of which relates to aluminum and the second to wood.

Estimating is done on the basis of the house project. As an example for self-calculation of materials, consider a small building made of foam blocks on a strip foundation, consisting of three rooms, a kitchen and a terrace.

Foundation estimate

Since foam concrete is a light material, when building a bath, summer kitchen or a small summer cottage, you can use screw piles. According to experts, a tape-type foundation is more suitable for building a house of 1-2 floors. It can be monolithic or prefabricated, buried or shallow. Such a foundation for a house looks quite laborious and costly, but it has a big plus. Strip foundation makes it possible to lay a basement or cellar under a foam block residential building.

In terms of kitchen equipment, the owner can either buy a turnkey kitchen or buy it in pieces. Don't forget the garden section in the villa example. Indeed, setting up a garden requires an investment in terms of grass, perhaps seeds, hedges, plants that can add to the value.

As far as the villa is concerned, the house also generates a significant investment for finishing details. However, it remains below the budget for finishing the villa and can be cut in half. For many, expenses are not necessary for a modern Moroccan home, like setting up a garden and setting up a terrace.

A monolithic base, difficult to manufacture and reliable in operation, is well suited for the sample. Sour cream construction works will contain all the costs of his device.

1. For a site with non-porous soil, choose a shallow foundation with a depth of 0.6 m. The trench must be dug 20 cm deeper to make a sand cushion.

Before laying the first stone, what is the cost? Some tips and tricks for estimating the total cost of your next construction. The price per square meter can vary significantly from one municipality to another. To this amount are added the fees of the architect, from 7 to 10% of the construction budget. They are payable in installments. Good to know: the contract is to fix the percentage and the pieces. The construction of a new house does not entail any notary costs, except for the purchase of land, the total cost is 15 to 20% of the purchase price and 25% in the case of a public sale. These include registration fees, administrative formalities, mortgage transcription and notary fees, as they will be responsible for registering your land in the cadastre. A standard finish will cost you less than a deluxe finish on the Council. Combine both by investing more in shared living spaces and saving on other spaces. Sustainable methods and materials are often more expensive but more beneficial in the long run. out of value. Decide if you only want to set up a garden when you have a budget.

No new construction, no land.
They can reach 10% in the Flemish region and 12.5% in Wallonia and Brussels.

You are going to build and you are digging ideas without being able to have a figure in front of each one.

For blocks measuring 600 × 300 × 200 mm, set the width of the base to 0.5 m.The foundation for the house will be poured into the formwork from the outside, so its final height is 0.6 + 0.4 = 1.0 m.

Our form will allow you to get an estimate of the cost of building your individual house... Either you haven't contacted a professional and don't have a quote yet: these pages will allow you to get a more or less rough estimate of your project and see if it's compatible with your budget. Either you have a quote, but before you sign, you want to check several options for your plan and your objects to make sure you have chosen the right one. However, you can easily get a better idea of your budget. ... In this case, the estimate will be more accurate: calculate the value of the house that you are evaluating using our form.

2. Determine the length of the tape:

(8 × 2) + (6 × 2) = 36 m, external walls;
8 + 6 = 14 m, internal partitions;
4+ (1.3 × 2) = 6.6 m, terrace.

The total length is 48.6 running meters.

3. Calculate the volume of concrete required for pouring monolithic foundation: 48.6 (tape length) × 1.0 (base height) × 0.5 (base width) = 24.3 m 3.

4. In the estimate for the construction, we list the components necessary for self-mixing (if you wish, you can order a ready-made prefabricated solution). Their number is determined based on the concrete grade M300. For 1 m 3 of the mixture you will need:

385 kg of M400 cement;
1080 kg of gravel / crushed stone;
705 kg of coarse sand;
200-220 liters of water.

To find out how much each material is required, we multiply the parameters of the standard tab by the fill volume:

385 × 24.3 = 9.367 tons of cement;
1080 × 24.3 = 26.244 tons of crushed stone;
705 × 247.3 = 17.132 tons of sand;
540 l water (depends on the moisture content of the components).

Buying the perfect land to build the perfect home is the dream of many. Choose the layout, the size of each room, the presence or absence of a mezzanine, the material for its creation, the presence or absence of a garden: practically living in a place made by one's own mind and partly by one's own hands. But how much would it cost to build a house from scratch?

What we offer is a short practical guide written by our editorial team in close contact with a qualified team. technical experts... A guide with which we will try to understand how to build a house in Italy.

5. We calculate the amount of sand for filling under the foundation of a house from foam blocks:

48.6 (tape length) × 0.5 (width) × 0.2 (pillow thickness) = 4.86 m 3. Round the result to 5 and in total we get 17.132 + 5 = 22.132 tons of sand.

6. When building monolithic base reinforcement is always needed. For our sample, we select a frame from two longitudinal rows, 2 rods each with a diameter of 12 mm. For transverse rows, a reinforcement with a cross section of 10 mm is required. With a spacing of jumpers of 0.5 m, the cross section of the frame is 30 × 0.65 m, the length of the rods is 0.35 m (horizontal) and 0.7 m (vertical). In total, one structure (ring) will need 0.35 × 2 + 0.7 × 2 = 2.1 m.In addition, for the joints on the jumpers, you need to provide tires 3 × 4 = 12 pcs. 1 m each.Total 12 meters or 2 rods of 6 m each.

How to build a house in Italy: what are all the decisions you have to make?

First of all, there is a choice: request a turnkey quote or when a company decides to build a house from scratch; or choose each professional and direct his own work, perhaps become manners. If the choice is to build a house, directing jobs as if we were some kind of impresario, the first research to be done is to explore the land.

But now we are more and more worried about the whole procedure

First of all, we must take possession of the building site. Buying land is just the first step. The second step is excavation, and it should cost from 15 thousand to 20 thousand euros. If after the first digging the specialists realize that the land is still unable to conduct the house, then another 20,000 euros will be required to consolidate the base.

7. Determine the total amount of reinforcement for the estimate for the construction of a house made of foam concrete: 48.6 × 4 + 12 = 206.4 m or 35 rods of 6 m with a diameter of 12 mm.

8. We calculate the number of rings for lintels: 48.6 / 0.5 + 1 = 98 sets or 35 rods of 6 m each.

9. For tying the reinforcement, use a soft steel wire at the rate of 0.5 m for each connection. For jumpers, you need 98 × 4 = 392 pcs, for tires 12 × 4 = 48 pcs, a total of 440 stitches × 0.5 m = 220 meters.

The roof instead requires another 1,000 euros. The costs that can be added to the possible costs are approximately € 000. Now it is time to realize, or to do the work. The electrical system costs about 13 thousand euros; a boiler and underfloor heating system cost about 28 thousand euros; Finally, water, gas and light compounds are about 3 thousand euros.

All materials and craftsmanship must be added to the cost of the architect who is involved in the project, coordination of works, certificates and tests, up to a modest figure of at least 30 thousand euros. The latter costs are the costs of finishes, but they depend on the materials chosen. In general, we can say that they cost at least 50,000 euros.

Estimate for foam concrete blocks for the construction of a box

In the project of a 6 × 8 house, we plan to lay load-bearing walls in half a block. For internal partitions, a quarter of a stone is sufficient.

These costs and expenses can vary greatly depending on whether the home owner is involved. If you plan to arrange a garden, paint inside the house, and do simple crafts, then the total price can also drop by 30%. However, this requires some practical skills, willingness and time to learn and collaborate.

How much does it cost to build a house? Borrowing amount, construction of this size can cost from 240,000 to 270,000 euros, excluding land. If the latter is not yours, but you have to buy it too, then you can easily get to the roof of 400 thousand euros. Obviously, we have to add furniture costs, which are at the discretion of those who enter. For young couples, there is also a double mobile bonus from.

0.06 m - the area of the spoon or the side of the foam block (200 × 300 = 60,000 mm);
0.18 m is the area of the bed or base of the block (300 × 600 = 180,000 mm).

1. In a house made of foam blocks, we choose a wall height of 2.8 m. It will require 14 elements in half a block. Taking into account the seam joints (14 pcs. 0.5 cm each), we get 2.87 m. In fact, the height of the walls inside the room will be 2.6-2.7 m (reduction due to the ceiling and screed).

More and more people are starting to solve their housing situation by starting to build a new family home. There are several reasons for this decision. Therefore, building a family home is definitely a very attractive alternative for everyone. Before you enter a building, think about what you can afford. After all, building a home is the most expensive thing you can do in your life. The poor financial plan failed to rebuild or exaggerate the construction performance.

Therefore, the question arises, how large are the financial costs that the builder should count on. A builder who plans to build a house for the amount indicated above should understand that his journey to the desired house leads only through a self-built building. You will be successful when your family and friends are helped by the building that is best equipped with the craftsmanship or construction machine. Substantial savings can be obtained by purchasing building materials with various sales and discounts and by transporting material on site.

(8 + 7.3 + 8 + 6 + 4 + 1.3) × 2.8 m = 96.88 m 2 - the area of the bearing walls.

For construction you will need: 96.88 / 0.06 (S spoon) = 1615 pcs of foam blocks in half a stone.

2. Determine the area of the internal partitions: (8 + 3 + 3) × 2.8 m = 39.2 m 2. For their construction, foam blocks in a quarter of an element are required: 39.2 / 0.18 (S bed) = 218 pieces.

3. In total, in the estimate for construction, we indicate the following number of foam concrete blocks: 1615 + 218 = 1833 pieces.

However, all the savings will come out once you find that unprofessional work and poor material choices have building flaws that you will need to remove. For this amount, you can imagine a house without basement floor with a living attic and a garage. Typical examples of homes in these price ranges are buildings in satellite cities. In many cases, these are development projects supported by a strong financial partner - a bank.

The result is an affordable home price that satisfies the design quality and many related services. If you want more than the standard from your home, you will need to invest over three million. In a more modest version, for example, the so-called two-generation house. The house is usually designed so that the ground floor has a kitchen, living room and necessary sanitary facilities. The second floor has bedrooms, rooms and an office. You can also enjoy the finest building materials and standard furnishings.

4. We find out the volume of dry glue for seams in load-bearing walls from the foam block. We have 14 horizontal (2.8 / 0.2 = 14) and 58 vertical (34.6 / 0.6 = 57.6 m) connections 0.005 m thick.

The total length of horizontal joints: 34.6 × 14 = 484.4 m, the amount of glue for it: 484.4 × 0.3 × 0.005 = 0.7266 m 3.
The length of the vertical seams is 58 × 2.87 = 166.64 m, respectively, the glue will go 166.64 × 0.3 × 0.005 = 0.24969 m 3.

The total consumption is 0.7266 + 0.2499 = 0.9765 m 3 or 1000 kg.

In this case, this is already non-standard housing in multi-storey buildings and often in conjunction with the homeowners' registered office. Residential buildings are built in attractive locations with good transport services. The owners boast not only traditional living spaces, but also a gym, swimming pool, sauna, library and workspace tailored to the owner's needs.

Housing is often accompanied by interesting architectural features. The builders' experience clearly indicates that when building a turnkey home, the most important choice is the construction company and independent construction supervision. This will save you a lot of anxiety and provide a lot of financial resources.

5. We calculate the glue for the construction of internal partitions with a total length of 14 m. We have 10 horizontal (2.8 / 0.3 = 9.3) and 24 vertical (14 / 0.6 = 23.4) seams.

Total length of connections: (14 × 10) + (24 × 2.8) = 207.2 m.

Adhesive volume for interior walls: 207.2 × 0.2 × 0.005 = 0.2072 m 3 or 270 kg.

6. Total consumption of dry adhesive mortar for a foam block house: 1000 + 270 = 1270 kg or 51 bags of 25 kg each.

When drawing up an estimate for the roof, it is better to involve specialists. This is a complex structure, which is difficult to build on your own. The opinion of professionals will also be needed when calculating the costs of plumbing, insulation and house cladding.

Basic construction costs table

By combining all the items of expenditure, we will receive an estimate for the construction of a house from turnkey foam blocks.

If the construction work is carried out independently, then greater accuracy in the calculations is not required. It is enough to take into account the main items of expenditure and find out the prices in force in the region.

How to save money on building a foam concrete house?

First of all, it will help to reduce the budget right choice dimensions of foam concrete blocks. In cold regions, the main task of construction is to keep the house warm. For these purposes, foam blocks of 600 × 300 × 200 mm are best suited. It is convenient to lay them in any way, varying the thickness of the box at home to the desired size. In this case, the number of blocks will always be as small as possible and without unnecessary costs.

To reduce the construction estimate for the cost of foam blocks and other materials, it is better to contact the manufacturer directly. Wholesale prices can be reduced by 5-15%. It is not worth saving by buying cheap foam concrete of dubious quality for construction. The additional cost to fix the uneven walls of the house will cover the difference and may even exceed the estimate.

The price of factory-made ready-made concrete looks more expensive than a home-made mortar for building a house. But saving on manual kneading can result in large losses of working time and unnecessary labor costs.

Calculating the approximate cost of building a foam concrete house, bookmark bulk materials you always have to do more. When unloading, sand, crushed stone or gravel usually crumbles and remains on the ground. Additional purchase and transportation increases the cost of the entire construction.

When choosing a mixture for laying blocks, it is advisable to give preference to adhesives for special purposes. Their price is definitely higher than that of cement mortar. But the consumption is an order of magnitude less. In addition, foam concrete masonry with glue retains heat much better.

When building a house from foam blocks with brick cladding, you can facilitate calculations using an on-line electronic calculator. When ordering an estimate for a turnkey foam block house, it is advisable to contact several contractors at once. The prices for services are different for everyone, so it is not difficult to choose an option that is acceptable in terms of cost and deadlines. If necessary, you can always amend the estimate for the house.
