it's still up there this morning, so shouldn't be a problem

the hole for the french doors is 1800mm, the lintel is 2100mm so that is 150mm each side

righthooker yes i'll be doing the brickwork myself. i don't expect it will be brilliant for a first go, so have no problem posting the after pics up for you to 'laugh at'. it's only an outhouse, so i'm not too bothered what it looks like. will probably be putting a trellis up on that side anyway
