Hi, I am planning on building an extension to my house. I already have an extended kitchen. This is 5m by 4.5. I would like a bedroom and bathroom build directly above that. I also have space immediately to the side of this kitchen. 5.5m by 4.5m. I would like a double storey extension built there. This will consist of two outer walls as it will share a wall with kitchen and share a wall with existing house. Please can you give me a cost estimate as I need to see if I can afford to go ahead. Also can you please provide details of a few reasonably priced but good builders in Oldham. Thanks.
