If you have enough garden amenity, building an extension can be a great way to add space and value to your home. According to the Offi ce for National Statistics, a typical 20m2 extension would increase the market worth of a property in England or Wales by an average of £47,260. The examples featured here offer a good indication of what you can expect to pay for different types of extension constructed to a fairly standard level of quality, using a main contractor.
