Question 1

What is a prefab timber frame house?

Accepted Answer

A prefab timber frame house is a building whose load-bearing timber frame and wall panels are manufactured in a factory and then transported and assembled on site. Factory production ensures precise dimensions, controlled quality, fast assembly and high energy efficiency.

Question 2

How are prefab timber frame houses manufactured?

Accepted Answer

We engineer the structure from the project drawings, then produce the timber frame and the wall, floor and roof panels in our factory using C24 graded timber, OSB sheathing, mineral wool insulation and membranes. The finished elements are delivered to the site and assembled into the complete house.

Question 3

What materials are used in your prefab timber frame houses?

Accepted Answer

We use C24 strength-graded coniferous structural timber for the frame, OSB panels for sheathing, Rockwool mineral wool for thermal and acoustic insulation, and vapour-control and waterproofing membranes. All materials are chosen for durability, energy efficiency and a healthy indoor climate.

Question 4

Do you use C24 structural timber?

Accepted Answer

Yes. The load-bearing frame is built from kiln-dried coniferous timber graded to strength class C24, which offers high load capacity and dimensional stability. The timber is treated to resist moisture and pests.

Question 5

Can you manufacture a prefab house based on my own architectural design?

Accepted Answer

Yes. We build custom houses from the client's own architectural project and prepare the full technical and production documentation for it. Each house is engineered individually to your drawings and requirements.

Question 6

How long does it take to manufacture and assemble a prefab house?

Accepted Answer

On average the whole process from design to assembly takes about 3–4 months. Technical documentation takes around 7 weeks, and on-site assembly of the frame typically takes 5–14 days depending on the size and complexity of the project.

Question 7

How much does a prefab timber frame house cost?

Accepted Answer

Prices start from 220€ per m². Every house is custom-engineered, so the final cost depends on the design, size, specification and finishing level. We provide an individual quote for each project, usually within 24 hours.

Question 8

How energy efficient are prefab timber frame houses?

Accepted Answer

Our houses reach A+ energy class. A timber frame with thick Rockwool mineral wool insulation, airtight membranes and high-performance windows minimises heat loss, keeping heating and cooling costs low and supporting passive-house level performance.

Question 9

How long does a prefab timber frame house last?

Accepted Answer

A properly built and maintained timber frame house lasts for generations — well over 100 years. Kiln-dried C24 timber, correct moisture protection, ventilation and quality membranes prevent decay and keep the structure sound long-term.

Question 10

Do timber frame houses suffer from moisture or mold problems?

Accepted Answer

No, when built correctly. We use kiln-dried timber, vapour-control and waterproofing membranes and a ventilated wall build-up that manages moisture and prevents condensation, protecting the structure from damp and mould throughout its service life.

Question 11

Are prefab timber frame houses fire resistant?

Accepted Answer

Yes. The wall build-up provides the required fire resistance: non-combustible Rockwool mineral wool (Euroclass A1) and gypsum board linings protect the timber frame and slow fire spread, meeting European fire-safety requirements.

Question 12

Can prefab timber frame houses withstand strong winds and earthquakes?

Accepted Answer

Yes. Our structures are engineered to Eurocode 5 (timber design) and Eurocode 8 (seismic design). Timber frame construction is lightweight yet strong and flexible, which makes it well suited to high winds and seismic loads.

Question 13

What certifications and quality standards do your houses meet?

Accepted Answer

Our houses meet European quality and construction standards. We hold CE marking, ETA (European Technical Assessment) and ISO certification, build with C24 strength-graded structural timber, and design our structures to Eurocode 5 and Eurocode 8.

Question 14

Which countries do you deliver prefab houses to?

Accepted Answer

We manufacture and deliver across Europe, including Italy, the Netherlands, France and Norway, as well as other European countries. Houses are produced at our factory and transported as ready elements for on-site assembly.

Question 15

Can I visit your factory or completed houses before ordering?

Accepted Answer

Yes. Factory visits to our plant near Olaine, Latvia are available by appointment (Monday to Friday, 09:00–17:00), and we can arrange to show completed projects and reference houses so you can see the construction quality and finish before placing an order.

Question 16

Why do you use 70×195 mm wall studs instead of standard 45 mm timber framing?

Accepted Answer

The 195 mm depth allows a thick continuous layer of mineral wool insulation inside the wall, giving far better thermal performance than a standard 45 mm frame. The larger cross-section also increases the structural strength and rigidity of the wall.

Question 17

What warranty do you provide for your prefab timber frame structures?

Accepted Answer

We provide a 10-year warranty on the house structure. The structural design, C24 timber and controlled factory production are intended to deliver a durable building that lasts well beyond the warranty period.

Question 18

How do your houses differ from Scandinavian and North American timber frame construction?

Accepted Answer

We combine deep, heavily insulated Scandinavian-style walls with precise factory prefabrication. Our 70×195 mm frame and thick mineral wool insulation give higher energy efficiency than the lighter 38–45 mm framing common in North American construction.
