Timber house price depends on the project

A closed panel shell starts from €500/m² + VAT at 150 m² or more. For 100 m² to less than 150 m², the base shell rate is €575/m² + VAT. These rates assume Comfort panels and a simple rectangular house.

Rates use the gross external floor area across all storeys. The shell includes insulated external wall and roof panels, internal walls, transport and assembly by our crew. The externally finished package adds facade cladding, windows, external doors and roof covering. Foundations, interior finishes, building services and site costs are excluded. Quotes are in EUR; GBP equivalents are indicative. The final price and scope depend on your drawings, specification and site conditions.

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

Grey-stage finishing usually means plasterboard is installed, while painting and floor coverings remain to be completed.

Interior finishing, including fitting plasterboard, is not included in either the ZTC shell or the externally finished package. Arrange this work with your local contractors. The quotation defines the exact division of work; “externally finished” describes the outside of the house, not the interior.

White-stage finishing usually means plasterboard is filled and painted and floor coverings are installed.

This interior finishing is not included in either the ZTC shell or the externally finished package. Your local contractors or project team arrange the interior fit-out and building services. Agree the completion standard and responsibilities in the project specification.

Standard wall U-values are Comfort 0.167, Premium 0.136 and Lux 0.100 W/m²K.

The specified U-value depends on the complete wall build-up agreed for the project, including layers installed on site. Whole-building energy performance also depends on windows, junctions, airtightness and building services. Your design team coordinates these with the project’s energy assessor.

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.

The final EPC rating depends on the complete building specification and is determined by an accredited assessor for the project.

Insulation, windows, airtightness, heating, ventilation and renewables all affect the result. The project’s accredited assessor determines the final EPC rating from the full specification. ZTC panels can support the agreed energy target, but a structural package alone cannot guarantee an EPC rating. Your design team should coordinate the full specification with the assessor.

Energy calculations are prepared during the design stage, before the panel specifications are finalised, and updated for the completed building.

The client or design team appoints a qualified assessor. Agree responsibility early so the calculations can guide the insulation, windows, airtightness, heating, ventilation and any renewables before manufacture.

Yes. ZTC manufactures timber frame panels in Latvia and provides transport and on-site assembly in the UK according to the agreed project scope. Your local architect or project team is responsible for architectural drawings, approvals, foundations and site readiness. The offer sets out the exact division of work.
