The place I might put wardrobes has the power sockets and phone connection behind it, so I'd want to have the wardrobes slightly out from the walls (like 5cm). Would that be OK? They'd be things like IKEA Pax or John Lewis Mix-It wardrobes, probably not the really tall ones though. I could stick little wedges under the front if needed to tip them back a bit? They'd be on carpet, if that matters.
If they do need to be attached, I don't know what I'd use. I don't know what the interior walls are made of. The brief survey thing (it's a new build) said that the walls are modern concrete frame with brick cavity infill, but I don't know if that's just the exterior. One set of wardrobes would go on a wall that is totally interior to me, and the other on the wall between two flats, which isn't totally exterior either I guess. I don't know what sort of fixings I'd need to get (I would hire someone to actually do it of course, not wanting to mess anything up!).
Also, I've heard less good things about the sliding door wardrobes, as the sliding bit can go wrong. I also prefer the look of hinged doors, but I might have to go with sliding for space. How much room, realistically, would you need between wardrobe and the bed? The wardrobes are generally 60cm deep, and 50cm wide, which should mean the door is also about 50cm, so that is 1m 10cm, plus the room you need for standing and bending to get stuff in and out. I guess you can sort of stand in between the doors once they're open, so maybe 30cm of clearance is enough? It's a small room and I need to get as much storage in as possible!
