I am looking to extend my house by adding a two storey side return.
Dimensions would be roughly 10m long by 4m wide. The space downstairs would
be a garage and kitchen extension, upstairs would be a bedroom and
en-suite. Anyone care to hazard a cost for this? Ballpark would be fine, or
even an average m2 price. Location is central Scotland.

my understanding is
£1000/m^2 for basic build (basic structure, walls, roof, floors)
£1500/m^2 for finished to a basic state
£2000/m^2 for finished and furnished.

less if you DIY, more if you want high spec materials
