I am planning to build a "floating" platform that needs to be able to hold at least 200kg (440 lb), the problem is, I can't attach it to three walls, as there is an exit on the third wall. My question is: is this possible, or would it have to have a pillar on the unsupported corner? Here is a birds eye view with dimensionsDrawing badly scanned in Thanks, Ben

EDIT: It's basically a floating bed, strain wise.

Wouldn't need to have a pillar. Would need at least a diagonal brace securely mounted to the wall framing. Unless, that is, you can build a boxed platform rigid enough to carry that stress without flex.

I'd use 3-5 heavy duty brackets like this.You'd barely be able to see them under your platform, leaving it with a floating appearance. Leave the end one 20-40cm from the end to help hide it visually.

I've built several such surfaces with good results using 2-1/2" lag screws. The brackets should ideally reach about 2/3 the way to the front or could be extended with structural top rails.

This question comes along regularly in various forms. Here are a few.

  • Thanks, Do lag screws work in aerated concrete, or would I use some sort of heavy duty wall anchors? Also would this work? – Landless9913 Mar 13 '18 at 21:47
  • I haven't worked with aerated concrete, but I'd guess that anchor would work fine. You must use some sort of expanding anchor, as concrete screws alone wouldn't have enough bite. – isherwood Mar 14 '18 at 13:11

Anchor that corner to the ceiling with some cable and eye bolts.
