Hello,
I'm planning on having a single storey extension built onto the rear of my house. It will be 6m x 4m in size with a flat roof. For a bit more light and interest I would like a rectangular roof lantern too.
I am interested to get an idea of the cost associated with this work. It will be used as a kitchen - but I will do the kitchen myself so I am trying to get an idea of the cost to build the shell, wire it and plaster board / skim it (excluding the kitchen). I have read that £1,200 pe m2 is about right, but is that for a finished room?
It should be an easy job - the extension will take up half the existing patio area (which is level) and access is easy. One of the 6m walls already exists as the brick built garage runs down the side of the patio already. One of the 4m walls will be formed by the rear wall of the house so in simple terms I need to build the remaining two walls and put a roof on it.
I assume the exsting garage wall may need underpinning if I use it as to support the roof structure of the new extension.
Is 1,200 per m2 about right? In my mind I had a budget of £30,000 for the structure but I wonder if this is actually a bit high...
Thanks guys - I know you can't provide an accurate figure but a guide would be great. I'm on Surrey / Hampshire border if that makes a difference.
