Prefabricated Timber Homes, Designed Around Your Project

Prices are quoted in EUR. Request a project quote for the agreed specification and scope.

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

After project approval and contract signing, production can usually be scheduled within 1–3 months. Manufacturing starts from around 2 weeks, while an externally finished house is typically completed within 1–2 months depending on scope.

After project approval and contract signing, production can usually be scheduled within 1–3 months. Manufacturing requires at least around 2 weeks. On-site construction depends on the scope of work — an externally finished house is typically completed within 1–2 months. Overall, a house assembled on site is often ready in approximately 4–6 months.

ZTC does not prepare architectural drawings. The company works from a client or architect’s project and provides structural solutions, manufacturing and assembly.

ZTC does not prepare architectural plans. We work from a project prepared by the client or architect and provide engineering/structural design, manufacturing and assembly.

ZTC mainly builds individual projects and respects owners’ privacy. If a project is under construction, a visit may be arranged, and you are always welcome to visit the ZTC factory.

ZTC houses are designed for a service life of at least 50 years. The standard warranty is 3 years, but in some cases it may be possible to agree an extension to 5 years.

Houses are designed for a service life of at least 50 years. The standard structural warranty is 3 years. In some cases an extension to 5 years may be considered where supported by material suppliers.

ZTC does not build foundations. Foundation design and construction are the client’s responsibility and depend on ground conditions, but timber structures are lightweight so strip foundations or piles are often suitable.

ZTC does not build foundations — this remains the client’s responsibility. Strip foundations are commonly used, but piles are also possible. The choice depends on ground conditions. Timber structures are lightweight, so several foundation types may be suitable.

Payments are made in stages: 10% on contract signing, 35% before production, 40% before loading, 10% on completion at site and 5% after the handover certificate.

Payments are made in stages: 10% on contract signing, 35% before production starts (covered by ZTC advance payment guarantee), 40% when production is complete and the loading date is confirmed, 10% on completion at site and 5% after signing the handover certificate (the last two payments are covered by the client’s bank guarantee).

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

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.

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.
