Hello,
we are currently finalizing all options with the home builder. The standard walls have single plasterboard, and insulation around wet areas. We will choose insulation everywhere, as well as OSB in most places, but not in areas that feel a bit underutilized like the highest wall in the living room with a ridge/lean-to roof and inside the walk-in closet and such. Does it feel penny-wise, pound-foolish?
Question two: how is it to mount things on walls with single plasterboard + OSB, do you just use gypsum/wood screws, and can you safely skip searching for a stud for heavy items like wall-mounted TVs and wall cabinets, etc.?

Foolishly frugal, well what's the savings?
In the closet, I've found OSB quite useful; all the ELFA gadgets with accessories are rock-solid here!
Yes, just screw it in. However, I've also used kortlat for kitchen cabinets, bathroom cabinets, etc. If you have enough screws, the stuff is awesome! It would take a lot for the OSB board to collapse (and bring down the whole wall), right

Nah, oh heck, do you think it's penny wise and pound foolish?? Gee whiz.... why is that? It will be tons of extra square meters to have OSB everywhere.... sigh, I don't want to be a penny pincher, the savings are based on the fact that the carpenters are supposed to do this
why is it bad not to have OSB way up above the sofa?

Sorry, but that's exactly where I would want to see OSB!Pedda_P said:
Sure, you (the carpenters) put up noggings for today's kitchen/bathroom dimensions, but what happens when you or someone else wants to change/renovate? Then the dimensions have to match
I was "saved" by OSB in the bathroom myself - I had forgotten to put up noggings for the (heavy) shower walls. Luckily, OSB was behind, it's holding up perfectly today!
Good!
Cost has such a dull ring to it, we call it an investment for the future
You will find great use for OSB when things need to be set up in the house later. That it then gives a more "solid" feel to the house isn't wrong either. I don't have a single crack/deformation in my painted walls/ceilings after 1.5 years. The damages that exist are the children's doing
