How Much For a House Extension

How much you'll spend on extension services in southfields and surrounding areas like Barnets and SW18 depend on the type of home extension design you need. Side return house extensions are cheaper than single-storey extensions. If you want wraparound or double-storey extensions, you will also have to spend more than you would in a single-storey design. Other things that determine cost include your taste, the planning authority, property type, and the scale of your dream home.
