Ļoti profesionāls un ieinteresēts darbs no ZTC puses, lai maksimāli izpildītu klienta vēlmes mājas būvniecībā, ieguldot laiku visu detaļu precizēšanā, kā rezultātā pašas būvniecības laikā neko nevajadzēja koriģēt un ir tapusi patiesi kvalitatīva māja. Atzinīgus vārdus par mājas būvniecības kvalitāti saņēmām no visiem speciālistiem, ar kuriem sadarbojāmies vēlāk - liekot logus un durvis, jumta segumu un apdari. Paldies par paveikto un varam tikai ieteikt citiem izmantot ZTC pakalpojums māju būvniecībā! Pateicībā, Irēna un Janeks

Factory-made timber frame structures

ZTC develops the structural design from the client's or architect's plans, manufactures the panels and assembles the house structure. Factory production helps control precision and plan assembly, while the energy performance design is tailored to the house.

What ZTC provides and what is planned separately

ZTC provides

  • Timber structural design based on the client's or architect's plans.
  • Panel manufacturing in the 4,500 m² factory in Latvia.
  • A CE-marked system with ETA-21/0014 European Technical Assessment.
  • 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.

ZTC structures and manufacturing

Experience since 1991

ZTC was founded in 1991 and has completed more than 400 projects across 14 European countries.

Factory production in Latvia

We produce panels in a 4,500 m² factory with capacity for 30,000 m² of panels per year.

Precise CNC processing

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

Certified system

Timber panel houses carry CE marking and ETA-21/0014 European Technical Assessment.

Energy performance

Depending on the construction, a U-value of approximately 0.12 to 0.15 W/m²K and n50 < 0.6 are possible.

Frequently asked questions

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

From EUR 430/m² excluding VAT. The starting price covers an insulated, weather-protected timber frame panel package (shell), using the Comfort specification for a rectangular house with a simple layout and at least 150 m² of gross area. The EUR 430 and EUR 500/m² starting prices apply only from 150 m² gross area, subject to the conditions of the respective solution. Smaller houses require an individual quotation.

From EUR 430/m² excluding VAT. The starting price covers an insulated, weather-protected timber frame panel package (shell), using the Comfort specification for a rectangular house with a simple layout and at least 150 m² of gross area. The price is calculated using gross area measured along the exterior perimeter of the building. This is not the heated or usable internal area. We agree the area calculation and specification in the project quotation. The exterior-complete house is quoted individually. The stated starting prices of EUR 430 and EUR 500/m² excluding VAT are achievable only for houses with at least 150 m² of gross area and the specification and shape required for the respective starting price. Houses below 150 m² require an individual quotation; the starting rate cannot simply be multiplied by a smaller house area. For example, we do not offer panel production and assembly for a 100 m² house at EUR 43,000 excluding VAT based on the EUR 430/m² starting price.

Budget separately for foundations, plinth, interior finishing, building services, project documentation, crane hire, scaffolding, fencing and worker accommodation where needed. Delivery and assembly are included.

Both packages exclude foundations and plinth, interior finishing including plasterboard installation, electrical installation, heating, water and drainage, and ventilation. Also budget for architectural design, approvals, necessary surveys, external utilities and commissioning. 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.

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).

The wall U-value is calculated for the individual project using all wall layers, material properties and structural junctions. Comfort, Premium and Lux differ in frame, insulation and barrier construction; the panel specification name alone does not determine a guaranteed U-value.

The n50 value describes the airtightness of the whole building. The target is set in the design and the achieved result is verified by a building airtightness test. Joints, windows, doors and assembly quality also affect the result; the panel specification alone does not guarantee a particular n50 value.

Yes, ZTC structures can be adapted for A+ energy performance class. The result depends not only on wall insulation but also on building form, windows, orientation, airtightness, ventilation and heating systems.

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.

A preliminary energy assessment is carried out during the design stage before construction and the building authority process. It helps determine whether additional insulation or other technical measures are needed.

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

Choosing panel specification and house completion level

The starting price covers an insulated, weather-protected panel package (shell) in the Comfort specification. The house must be rectangular with a simple layout and at least 150 m² of gross area.

Comfort has a 195 × 45 mm frame with mineral wool. Premium uses a 245 × 45 mm frame with wood fibre or cellulose and a 22 mm wood fibre windproof board. Lux has a 340 × 45 mm frame with wood fibre or cellulose and a 40 mm STEICO THERM layer. Compare all included and excluded layers on the timber frame panel page.

You can choose the panel package or an exterior-complete house with facade finish, windows, external doors and roof covering. Neither includes interior finishing or building services. The cost page explains completion levels, delivery and the costs you need to cover separately.
