I've just had an extension done that was exactly the same dimensions as yours, with the addition of a single storey right the way along the back of the house as well. I put in the foundations / floor slab and got builders in to complete a water tight shell.
So bearing in mind that;
i) I had to have the garage section built.
ii) I had the single storey across the back.
iii) I had completed the foundations and floor slab
iV) I supplied and fitted the windows
total was £35,000 inc. I'd say that with the inclusion of a new boiler, plumbing and electricals you're going to be closer to noseall's figure.
As for timescales, it was quoted at 9 weeks, but took 13 due to some shockingly bad management of the subbies by the Builders.
I was thinking in around £40 - 45k completed.
Most others on here seem to think I have no chance tho....
Any advice?
