Short answer. A house-building budget has several groups: preparation (surveys, design, connections), construction (foundation, walls, roof, windows, facade), building services and interior finishes, plus landscaping and a contingency. RigaBuild’s indicative starting prices are from €1,400/m² for private house construction and from €1,800/m² for full-cycle construction (valid on 30 October 2026, excluding VAT, labour only). Materials are a separate part of the estimate. The cost of a specific house can only be calculated once the design, the scope and the completion level have been agreed.
Key points
- A price per m² is only comparable if you know which area and which work it covers.
- The completion level — weathertight shell, grey finish or full finish — changes the total substantially.
- Building services and the heating system are among the largest and most variable items.
- A contingency for unforeseen work and changes is a required part of the budget.
What a house budget is made of
| Cost group | What it includes | What drives the amount |
|---|---|---|
| Preparation | Surveys, design, documents in BIS, connection conditions | Design complexity, plot conditions |
| Foundation | Earthworks, foundation, waterproofing, drainage | Soil, foundation type, insulation |
| Structure | Walls or frame, floors, stairs | Material, storeys, spans |
| Roof and windows | Roof structure and covering, windows, external doors | Shape, covering, number and type of windows |
| Facade and insulation | Insulation, finish, plinth | System, area, junctions |
| Building services | Heating, water, drainage, electrics, ventilation | Heat source, automation, connections |
| Interiors and finishes | Floors, walls, ceilings, bathrooms, kitchen | Completion level and quality of materials |
| Landscaping | Driveway, terrace, fence, rainwater | Plot and preferences |
| Contingency | Unforeseen work and changes | Design readiness, number of changes |
The plot itself is usually outside the construction budget, but it affects many items — connections, foundation and access.
The diagram places the cost groups on a house: 1 — foundation, 2 — walls and facade, 3 — roof, 4 — building services, 5 — interior finishes. It does not show the proportions between groups.
What a price per m² really means
A price per square metre is a useful orientation but can mislead unless it is clear:
- which area is used — total, heated or footprint;
- which work is included — construction only, or also services and finishes;
- what is excluded — materials, design, connections, landscaping.
Two estimates with the same price per m² can cover very different scopes. That is why they should be compared line by line, as shown in our renovation estimate example.
Completion levels
| Level | What is usually complete | What remains for the client |
|---|---|---|
| Weathertight shell | Foundation, walls, roof, windows and external doors | Services, facade finish, interiors |
| Grey finish | Plus basic services and rough interior work | Finishes, sanitaryware, kitchen, floor coverings |
| Full finish | Plus finishes and equipment within the agreed scope | Furniture, landscaping (if not included) |
Builders draw the lines between levels differently, so they must be described in the contract and the estimate.
What changes the budget most
- Area and shape. A compact house with a simple roof costs less than a complex one with many corners and roof planes.
- Structure and materials. Wall material, floors and facade system change both materials and labour.
- Foundation and soil. Weak soil or a high water table increases foundation costs — see house foundation costs.
- Building services. Heat source, underfloor heating, ventilation with heat recovery and automation.
- Who buys the materials. Materials can be bought by the client or by RigaBuild. RigaBuild can offer better prices through trade discounts, but that does not mean every item will always be cheaper. See who buys renovation materials for how to decide.
- Changes during construction. Every decision changed after work has started affects the budget and the schedule.
Contingency and changes
Even a well-prepared project meets unforeseen work: ground conditions, connection requirements, material availability or changes requested by the client. Size the contingency according to how complete the design is — the more detailed the design, the fewer unknowns. All changes should be agreed in writing with their effect on price and time, as described in change orders and extra work.
Planning the budget step by step
- Define the idea: area, storeys, completion level.
- Check the plot and connections.
- Commission surveys and the design.
- Get a line-by-line estimate with a clear scope.
- Agree who buys materials and when.
- Put the contingency and change procedure into the contract.
- Track the budget by stage — foundation, shell, roof, services, finishes.
The order of stages is set out in stages of building a house in Riga.
Before planning the budget, check the plot (what to check before buying) and compare builders’ offers against the same scope of work (choosing a house builder).
Common mistakes
- Comparing prices per m² without defining the area and scope.
- Budgeting without a design and surveys.
- Leaving out services and connection costs.
- Not keeping a contingency.
- Changing decisions during construction without a written agreement.
Checklist before asking for a quote
- □ Design, or at least plans, sections and material choices.
- □ Total and heated floor area.
- □ Desired completion level.
- □ Heating and ventilation approach.
- □ Who buys the materials.
- □ Landscaping work, if it should be included.
Frequently asked questions
How much does a 150 m² house cost to build?
An exact figure can only be calculated from the design, scope and completion level. For the same area the total can vary widely depending on structure, services and finishes.
Does the price per m² include materials?
RigaBuild’s published starting prices cover labour. Materials are a separate part of the estimate, and what is included is specified in the estimate.
Which items cost the most?
Usually the structure, roof and windows, building services and finishes. Their share differs from house to house.
Can I order only part of the work?
Yes, individual construction stages can be assessed as a separate scope if they can be clearly separated.
