Is there an exact price for building a house?
There is no single price per square metre that applies to every house. Two projects with the same gross floor area may have substantially different budgets because of the building shape, structural system, number of floors, terrain, roof, windows, installations and finishing materials.
The price should therefore be determined after reviewing the design, quantities and site. An early estimate is useful for planning but should not be treated as a final offer. A professional offer explains what is included, which materials are planned and at what completion stage the building will be delivered.
Main completion stages
When comparing offers, first check whether they refer to the same completion stage. Terms such as rough construction, shell finish and turnkey are often used differently by different companies. The safest approach is to describe every activity in detail.
What the different stages usually include
| Stage | Usually includes | What remains |
|---|---|---|
| Rough construction | Excavation, foundations, load-bearing structure, slabs, masonry and roof structure according to the agreed scope. | Installations, windows, insulation, facade and all finishing works. |
| Closed shell | Rough construction, roof, exterior windows and basic protection from weather. | Installations, plaster, screeds, facade, flooring, painting and equipment. |
| Turnkey | Construction and finishing works ready for furnishing or occupancy according to the exact specification. | Furniture, appliances, landscaping and activities not explicitly included in the contract. |
Request a detailed specification with every offer. The stage name alone is not enough for a fair comparison.
Which factors have the greatest impact on cost?
- **Architecture and building shape** — A compact rectangular form is usually more economical than a design with many corners, projections, terraces and complex details.
- **Terrain and access** — Slope, soil, groundwater and access for heavy equipment affect excavation, foundations and logistics.
- **Structural system** — The amount of concrete, reinforcement, formwork and masonry depends on the design and loads, not only on area.
- **Roof** — A complex pitched roof with many valleys and dormers usually costs more than a simple gable roof or a properly designed flat roof.
- **Energy efficiency** — Windows, insulation, airtightness, heating and ventilation increase the initial investment but may reduce future operating costs.
- **Finishing material class** — Flooring, sanitary ware, doors, lighting and decorative solutions can change the final cost by tens of percent.
How to calculate a realistic starting budget
Start with the total amount available and separate costs outside the building work itself. The budget should include the plot, transaction costs, design, surveying, geology, fees, utility connections, supervision, temporary facilities and landscaping.
Then divide construction into stages and set priorities. The structure, waterproofing, roof and concealed installations are not suitable areas for savings without engineering assessment. Some decorative solutions can be simplified or completed later.
Example budget allocation
The allocation differs for every project, but the following model helps identify cost groups that are often overlooked. The percentages are not a price offer and must be adapted to the specific house.
| Cost group | What to allow for |
|---|---|
| Design and administration | Architecture, structure, installations, surveying, geology, approvals, fees and supervision. |
| Preparation and structure | Clearing, excavation, foundations, concrete, reinforcement, formwork, masonry and roof. |
| Building envelope | Windows, waterproofing, thermal insulation, facade and exterior details. |
| Installations and finishes | Electrical, plumbing, heating, plaster, screeds, flooring, painting, sanitary ware and doors. |
| External works and contingency | Landscaping, fence, access, drainage, utility connections and unforeseen work. |
How to compare two construction offers
Do not compare only the final amount. Check quantities, brands or technical specifications of materials, included transport, machinery, waste removal, scaffolding, temporary facilities and responsibility for deliveries. A low price may result from missing activities that will be added later.
Clarify how work will be accepted and pay against actually completed stages. When the design changes, there should be a written description of the additional work, price and impact on the deadline. This protects both the client and the contractor.
How ALEKSIEV-SA approaches pricing
To prepare a realistic offer, we first clarify the location, design, site condition and desired completion level. After an inspection and document review, activities are divided into stages so the client knows what is included and how the budget is formed.
This approach does not promise the same price for every project; it provides better predictability and control. The goal is to make important decisions before work begins, when changes are easier and less expensive.

Frequently asked questions
How much does house construction cost per square metre?
There is no universal price per square metre. It depends on the design, terrain, structure, materials and completion stage. A realistic figure is determined after design review and a defined scope.
What is usually not included in the construction price?
The plot, design, fees, utility connections, landscaping, fencing, furniture and unforeseen work are often calculated separately. Every offer should be reviewed in detail.
What increases the cost of a house the most?
Complex architecture, difficult terrain, large openings, a complex roof, high-end windows and systems and luxury finishes can significantly increase the budget.
Is a contingency needed in the budget?
Yes. A contingency helps with unforeseen conditions, changes and price fluctuations. Its size depends on design readiness and the risks of the specific project.
Can an exact offer be prepared from area alone?
No. Area is only one factor. An accurate offer requires a design, specification, site information and a clearly defined completion stage.
