Wintering beams. Bad idea?

[joakim_j]

For various reasons, I won't be able to build as much this year as I had planned, but since the building permit is ready, I still want to start. It will be difficult enough to get it done within five years anyway. What needs to be built is an extension to my house, about 75 square meters with a basement, one floor, and an unfinished (but convertible) attic. I plan to do almost everything myself, if nothing else compelled by the economic situation.

At the very least, I plan to cast the foundation and basement walls (thermomur). They won't be damaged by standing outside over a winter, and I'll fill the underfloor heating loops with propylene glycol.

But I'm a bit eager to also try to get the intermediate floor in place. The idea is to build the intermediate floor and then construct a temporary roof with a tarp over the winter, which will stand until spring. Then, walls and a roof will be added in 2024.

Is it a bad idea? Could the wood be damaged by standing over the winter without heating? Spontaneously, I think it's no worse than a carport or shed or anything else unheated, and that works.

It will be hard enough to finish within five years anyway. What is to be built is an extension to my house, about 75 sqm with a basement, one floor, and an unfinished (but finishable attic). I plan to do almost everything myself, if nothing else compelled by the economic situation.

At the very least, I plan to pour the slab and the basement walls (thermomur). They won't be damaged by standing outside over a winter, I fill the underfloor heating loops with propylene glycol.

But I'm a bit tempted to also try to get the intermediate floor in place. The idea is to build the intermediate floor and then in winter throw together a temporary roof with a tarp on it, which can stand until spring. Then get the walls and roof up in 2024.

Is it a bad idea? Could the timber be damaged by standing over winter without heating? Spontaneously, I think it's no worse than a carport or shed or anything else that's unheated, and that works.

If it's just timber, there shouldn't be any problems, as long as any moisture can dry out before you enclose it anyway.

Yes, when I write "bjälklag" I naturally only mean the beams themselves, so no chipboard or anything else.
