Building prices for extension single storey
Total cost of project and m2 costs for having a single floor extension added to your home. The area of the house is usually specified by its internal floor area though sometimes it can be the external area. Also, pay attention in the detailed comments to what was and wasn't included in the build costs. A simple construction may be just a shell structure (basic plumbing, electrics and building work) whereas many people will specify the actual cost i.e. after you have put in all the fittings (e.g. new kitchen or bathroom/shower suite) furnished and decorated (including carpets or other type of flooring) the extension.

| I recently had an extension done by Building Fixers London. I am happy to say that I was very pleased with the reasonable price, standard of their work and their courtesy. In addition to the standard building, they had to reinforce the foundations before they could do the extension. They also fitted the kitchen from Magnet which they helped to source and also made some tailored units which we could not find anywhere. I had had other quotes. My extension was 4x3sqm and I paid £12600 for the extension and £3000 for the kitchen. This included painting and tiling, electrical and gas works. I would highly recommend them. By the way, the main builder is a woman! Tam.
