Google review

We are Premium Living AS in Norway and built two houses with this company. We were very satisfied. We sold the last project 2 years ago when I write this review, and the first house was built 4 years ago. With both houses, the production, planning and timing all went smooth and well organised. Right now, all three buyers are pleased, and we haven't received a single complaint about flaws or even blemishes. Even during the Covid lockdowns there was no doubt that our investments and cooperation with ZTC were solid. We recommend, and anyone that has questions can ask ZTC for our reference.

How factory preparation helps on site

We prepare much of a timber panel house's structure in the factory with CNC processing precision of ±1 mm. There, we control insulation and membrane installation and prepare panels for the assembly sequence. Read about timber frame houses or compare timber frame house costs.

What ZTC provides for panel houses and what is planned separately

ZTC provides

  • Timber panel design based on the client's or architect's plans.
  • Panel production in the 4,500 m² factory in Latvia with up to 30,000 m² of panels per year.
  • CNC processing with ±1 mm precision and a CE-marked system with ETA-21/0014.
  • The price includes panel delivery, assembly and worker transport to the site across Europe, Scandinavia and the United Kingdom. The client provides accommodation for workers where needed and pays site costs: crane hire, scaffolding and site fencing. Delivery sequence, site access and assembly arrangements are agreed in the project quotation.

Planned separately

  • ZTC does not prepare architectural drawings.
  • ZTC does not build foundations.
  • Both packages exclude foundations and plinth, interior finishing including plasterboard installation, electrical installation, heating, water and drainage, and ventilation.

Precise CNC processing

We process structural elements with CNC precision of ±1 mm.

On-site assembly

Panel assembly on site is typically around 3 to 5 days per floor.

Certified system

Manufactured timber panel houses carry CE marking and ETA-21/0014.

Frequently asked questions

Questions about panel technology, construction process, warranty and payment.

Comfort panels use mineral wool within the frame. Premium and Lux use wood fibre or cellulose insulation; Premium adds a 22 mm wood fibre windproof board, while Lux adds a 40 mm STEICO THERM wood fibre layer. Additional 45 mm internal insulation and plasterboard are excluded from these packages. For Comfort, Premium and Lux, roof panel insulation is 50 mm thicker than the insulation in the corresponding external wall.

Panels are connected with long screws or special timber connectors. A wind barrier is used externally, a vapour control layer internally, and membranes are carefully taped across the building.

Airborne sound insulation in timber houses can be very good, especially with cellulose or wood fibre. Impact sound in intermediate floors should be addressed with appropriate floor and ceiling solutions.

For houses up to around 3 storeys, timber frame is often more economical. CLT may suit load-bearing structures, hybrid solutions or where exposed solid timber walls are desired.

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 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. Foundations and plinth are excluded from both the panel package and exterior-complete house price. The designer selects a foundation solution using ground investigation and the building loads; the client arranges its construction.

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).

Panel production, delivery and assembly

We agree the panel specification and structural design before manufacturing. Before delivery, we confirm the assembly sequence and site access. This helps divide the work between the panel manufacturer and the other contractors.

The package includes load-bearing and non-load-bearing internal walls, each with a timber frame and 12 mm OSB on one side. The other side remains open for subsequent work.

Compare Comfort, Premium and Lux panel layers. The cost page explains the conditions for the EUR 430/m² starting price excluding VAT and the additional scope of the exterior-complete package.
