And the quality of kids house is really amazing!

Factory-made timber frame structures

A timber frame house suits private home projects where precise production, energy performance and predictable on-site assembly matter. ZTC works from a client or architect project, develops the structural solution, manufactures the panels and assembles the structure. See timber frame house cost, timber house price and timber frame vs masonry for related topics, or browse completed ZTC projects.

Frequently asked questions

Answers about timber frame house price, construction process, warranty, foundations and energy performance.

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.

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 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).

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.

Closed panel specifications

Three closed panel levels, one fabric first system

Every panel leaves our factory insulated, with a wind barrier on the outside and a vapour control layer on the inside, so only the top edge needs wrapping for transport.

The U-values below apply to walls only.
