Hello,
I also think that such a project is unlikely to be truly worthwhile.
Since we have just experienced the installation and interior finishing of a timber frame prefab house, we know quite well how complex the whole thing is.
Dismantling the basic elements of the roof and walls should not be a problem, but:
- Sanitary installation
- Electrical installation
- Heating installation
- Cladding of walls and ceilings
- Screed
- Wallpaper
- Flooring
- Interior doors
- Fireplace
- ...
are all elements that, after the house is erected, like in a solidly built house, are installed and, in one way or another, connected to the building.
Leaving aside the fact that it would be an extremely complex "puzzle" to dismantle and reassemble everything cleanly, I think many parts would be damaged or even destroyed during the construction work.
Thus, costly replacement procurement would already be necessary.
The required labor time and the resulting labor costs would probably be, roughly estimated, about twice as high as for conventional assembly of a prefab house – basically once dismantling and once assembling...
Transport over the not exactly short distance would also be a significant cost factor – aside from the fact that special semi-trailers should be used for transport, which are not exactly found on every corner.
There are also costs for the foundation slab and/or basement...
I would also not necessarily take the houses in a model home park as a basis for calculation – these houses often do not have all the connections necessary for normal habitation installed, starting with usually missing sanitary installations to often very limited electrical installations etc...
Long story short – I will now take a big risk: I cannot imagine that this project can be economically sensible to carry out.
Regards,
Dirk
