VAT and delivery arrangements
Ireland: VAT for business customers
For eligible supplies to VAT-registered business customers in Ireland, the customer accounts for Irish VAT under the reverse-charge rules. The applicable treatment depends on the supply, installation arrangement and the customer’s VAT status, and is confirmed in the quotation and invoice. Private customers do not qualify for this business reverse-charge treatment.
Irish Revenue guidanceUK: customs and import arrangements
Deliveries from Latvia to Great Britain (England, Scotland and Wales) require export and import customs declarations because the UK is outside the EU. The importer of record, customs clearance arrangements and responsibility for import VAT and any applicable duty are agreed for the project before dispatch. Northern Ireland follows a different goods regime; we confirm the relevant arrangements for each Northern Ireland project.

Why Choose ZTC
Fixed Contract Price
The contract price is the final price for the complete ZTC scope and specification agreed in your contract. We deliver all of that agreed work for that price, with no material surcharges or escalation clauses, unless you change the agreed scope or design after the technical design freeze. Any requested changes and their price are agreed in writing before the additional work begins.
Speed to Weather-Tight
Structural on-site assembly in 3–5 days per floor. Your project reaches weather-tight in weeks, not months and interior works start earlier, saving time and cost.

Selected Projects
Latvia — Developer project
Industrial Facility Facade with CLT and Infill Panels
Industrial Facade with Insulated CLT Infill Panels ZTC manufactured and installed insulated infill panels for the front facade of an industrial building. The panels combined an insulated external envelope with a 60 mm CLT interior face and were delivered ready for installation onto the building’s steel frame. Panel production took place alongside the erection of the steel structure, shortening the overall construction programme. Installation required no scaffolding, reducing site equipment needs and work on site. The exposed CLT provides a durable timber surface that can be refurbished when required, making it a practical choice for an industrial interior. The insulated panel build-up supports the building’s thermal performance, while the timber stores biogenic carbon. This project demonstrates how prefabricated timber infill panels can integrate with steel structures to deliver an efficient building envelope for larger industrial facilities.

Norway — Developer project
Modern Prefab Timber Housing Village with Fjord Views
This modern residential village consists of 8 two-story prefabricated timber frame houses, beautifully integrated into the surrounding nature and tailored to maximize the stunning nearby fjord views.
Norway — Developer project
7 private homes in Norway
A private house village consisting of 7 two-story private houses in Norway.
Norway — Developer project
4 two-story apartment buildings in Norway
The project includes two buildings of different designs – two buildings with a floor area of 470 m2 each and two buildings with an area of 630 m2. The roof structure of the buildings is made of wooden trusses. The supporting structure of the balcony is made of glued beams. Horizontal boards are used for the facade decoration. The wall panels are delivered with windows already installed in the factory.
Switzerland — Developer project
Three-story residential building project in Switzerland
The project was executed under challenging conditions, as there was virtually no construction site and no space for material storage, which required precise delivery planning. The building rests on a steel load-bearing frame, which allowed for the creation of spacious, open-plan interiors free of restrictive support structures. The exterior walls feature a plaster finish, while tile roofing was used. The staircase steps were manufactured from CLT. To reduce on-site labor intensity and the number of subcontractors, the panels were delivered with windows and electrical boxes already pre-installed at the factory.
Sweden — Developer project
20 Prefabricated Homes in the Stockholm Archipelago
These houses were built on an island near Stockholm. Despite complex logistics and COVID-19 restrictions, 16 houses were completed within 6 months, while the remaining 4 were prepared for delivery in the following season, in accordance with the client’s request. By utilizing Swedish-style construction methods and off-site exterior finishing, we ensured rapid on-site assembly. The quality of the project is confirmed by the Blower Door test, where the achieved air permeability of 0.12 L/s/m² is five times better than the regulatory requirement (0.60 L/s/m²), demonstrating our ability to maintain the highest quality standards even in large-scale projects.
What Our Clients Say
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.
