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 foundations or piles are often suitable. The specific solution is determined by ground conditions, topography and the architect project. See timber frame houses and timber house price.
Google reviews highlight ZTC’s precision, organised process and professional communication.

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.
