For anyone looking to extend their home rather than move I would recommend Plus Rooms. They have recently completed a side return and kitchen extension for us, along with some other internal works to our house. Their price was competitive, they completed the build on time and oversaw the project effectively. With any large project complications and the unforseen will arise, but they have been prompt and responsive in their handling of any issues we have had. If you are considering building an extension do ask them to quote for you.
