One of the questions we get asked a lot is how much a single-storey rear extension costs.
The honest answer is, it depends on the size, the layout, the amount of structural work involved, and the finish you want.
Every home is different, so it is always worth getting proper advice rather than relying on rough figures online.
If you are thinking about extending and want to know what might be possible, just drop us a message.
