We have a 2-bed semi in an ok area and can't afford to move. With DC2 on the way we've started looking into the possibility of extending to get a third bedroom and a kitchen you could actually swing a cat in. So a 2 storey job, going out where our garage currently is on the side of our house iyswim.
What's a ballpark cost for this sort of thing, and how disruptive is it? Can we still live here while it's being done? Also, the plan would be to add value to the house, so say investing 30k to extend but increase value by double that, allowing us to move in the future.
Any words of wisdom gratefully received
