We want to build a brick 'lean to' 1 storey extension to the side of the house. It'd be a max of 2.4 m by 2.4 m, have a sloping tiled roof and be 'open' inside to the underside of the roof with 1 or 2 velux windows; a normal double paned window to the front, and a single doorway opening into the house.
Will obviously need electrics but no plumbing etc.
Can anyone give me a vague idea about whether I'm looking at £5000 or £10000? Isn't there a cost per square meter thing?
