Hello,

I’d like to put up a picture shelf above my bed (IKEA MOSSLANDA). I was going to use rawl plugs in the plasterboard, but with it being above our heads I’d sleep better knowing it’s fixed in to a stronger material.

I’ve drilled in to the breeze blocks on other walls in my house to put up curtain rails, but never in a shared wall. I’m thinking i’d tape my drill bit at 80mm, so I’d have at least 10mm extra beyond the tip of the 5x70 screw. This would mean drilling 50mm in to the breezeblock.

Is there a standard thickness for breezeblocks/party walls? It’s a 1990s semi-detached house. I don’t want to drill through in to my neighbour’s bedroom!
