ZTC built my house in 2012, and they have done some reclamation work in two periods since then. Only positive experiences with ZTC! Good quality of workmanship and customer support.

Foundation choice depends on soil, geology and the project. ZTC manufactures and assembles timber structures but does not build foundations.

Timber frame structures are relatively light, so strip or pile foundations are often suitable. The choice depends on ground conditions, topography and the architectural design. Read about timber frame houses and timber house prices.

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

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.
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.

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.
