Hi, I am thinking of building a floating desk along a wall on my flat.
I would really like it to be a floating desk along the entire wall which is around 3.5 meters.
I am thinking of using an oak countertop
65 or 72 cm deep and 28 or 38mm thick.
The weight for a 350x65x3.8cm counter too is about 55kg. It will only be supported on the 2 short sides and 1 long side along the walls.
My first question is:
Will this be strong enough to self support and not sag in the middle? And is the 28mm thick enough or will it need the 38mm?
Secondly regarding the actual attachment to the walls which are MDF with a timber frame. My idea is to have 2x6s along the 2 short and one long side directly bolted into the timber frame. Then the countertop would rest on that and be attached with pocket-hole screws or brackets
Would I need some shelf brackets as well? Especially to avoid sagging?
