Question 1

What is a prefab house?

Accepted Answer

It is a building system in which factory-made panels and structural elements are assembled on site. The walls are usually sandwich panels with an insulating core.

Question 2

How long does it take to build a prefab house?

Accepted Answer

Generally between 2 and 8 weeks. The time depends on the size of the project, whether the foundation is ready, and the weather.

Question 3

Are prefab houses earthquake resistant?

Accepted Answer

Being light, a prefab house attracts low earthquake forces. As long as the structure and its connections to the foundation are properly calculated and assembled, it resists seismic loads well.

Question 4

What is the lifespan of prefab houses?

Accepted Answer

An average lifespan of 40-60 years can be expected. Regular maintenance of the facade, roof and panel joints extends it.

Question 5

Are prefab houses cold in winter?

Accepted Answer

Not if the panel insulation is chosen for winter use and the joints are airtight. It then stays cool in summer and warm in winter.

Question 6

How are prefab house prices determined?

Accepted Answer

Floor area, number of floors, panel quality and thickness, architectural design and any extras set the price. The foundation and utility connections also add to the total.

Question 7

Is a permit required for a prefab house?

Accepted Answer

Yes. A prefab house counts as a permanent building, and on zoned land a building permit must be obtained from the municipality.

Question 8

Can a prefab house be built on any land?

Accepted Answer

No. The plot's zoning must allow building. Agricultural land and plots near the shore can have extra restrictions, so the first step is always a zoning status enquiry.

Question 9

Can a prefab house be relocated?

Accepted Answer

Yes. It can be dismantled and rebuilt elsewhere, but dismantling, transport and a new foundation all add cost.

Question 10

Is a prefab house or light steel house better?

Accepted Answer

Prefab houses are cheaper and quicker to build. Light steel houses last longer, are more durable and allow more design freedom. For a summer house prefab usually makes sense; for year-round living, steel is usually the better choice.

Question 11

How is plumbing done in prefab houses?

Accepted Answer

Electrical and plumbing runs are planned in the design and installed during assembly, inside the panels or through channels left for them.

Question 12

Does a prefab house require maintenance?

Accepted Answer

Yes. The exterior, roof and panel joints in particular should be checked once a year. Near the sea, the facade paint needs renewing more often.
