Its basically about the cost factor of which we are totally unaware. I am planning an extension and my requirements are to build a bedroom and a small lounge which is going to be attached with the main house. As far as space goes our area has ample land but before proceeding I need to have a clear idea on the costs involved for this. This also covers the charges of materials, plumbing and the planning part. Can you help me?

House extensions vary greatly in cost, however, as a general rule in London, one may estimate at around £2,000 per square metre.
