Question 1

How much does a timber house cost?

Accepted Answer

The price depends on floor area, architecture, energy performance and specification. Indicative figures: structural stage approximately €650–750/m² + VAT; externally finished house approximately €850–1,100/m² + VAT. A precise quote can be prepared once more detailed plans are submitted.

Question 2

What additional costs should be planned beyond the house price?

Accepted Answer

Beyond the house price, you should plan for architectural design, approvals, topographic survey, geology, energy certificate, foundations, external utilities, heating, ventilation, interior works and commissioning.

Question 3

What is grey-stage finishing?

Accepted Answer

Grey-stage finishing means plasterboard is installed on the walls, but paint and floor coverings are not yet applied. It is an intermediate finishing stage before full interior completion.

Question 4

What is white-stage finishing?

Accepted Answer

White-stage finishing means plasterboard is filled, sanded and painted, and floor coverings are installed. It represents a higher level of completion than grey-stage finishing.

Question 5

What is the wall U-value?

Accepted Answer

Depending on the construction, ZTC timber frame walls can achieve a U-value of approximately 0.12–0.15 W/m²K. Wall thickness is typically 250–400 mm. The exact solution is determined during design and energy assessment.

Question 6

What is the n50 value?

Accepted Answer

The n50 value describes building airtightness. In quality constructions it is possible to achieve n50 below 0.6, which is important for energy-efficient buildings.

Question 7

Is it possible to achieve A+ energy performance class?

Accepted Answer

Yes, ZTC structures can be adapted for A+ energy performance class. The result depends on insulation, thermal bridges, building airtightness, windows, orientation, ventilation and heating systems.

Question 8

When is the energy assessment carried out?

Accepted Answer

A preliminary energy assessment is carried out during the design stage before construction starts. It helps determine whether additional insulation or other technical measures are needed. After construction, a final assessment follows to confirm compliance.

Question 9

Is a timber house suitable for the Latvian climate?

Accepted Answer

Yes, timber structures are suitable for the Latvian climate when correctly designed, insulated and built. ZTC structures are adapted to each project’s energy performance requirements.
