House Extension Costs

An extension to your house can be a easier option to moving for gaining more living space, but how much will it cost for types of extension of different sizes?The table below gives examples of the range of prices we have had submitted. As a rough idea you can typically say that it will cost £1000 per m² or  93 per ft² including basic plumbing and electrician work. This price is per unit area of internal floor space and so a 5x4m single floor extension will have a total floor area of 20m² and a double storey will have 40m².
