We have built a great reputation through Mansfield and Ashfield for constructing superb extensions to existing properties. An extension that is planned, fully designed and well-thought out and can make a huge difference to your home, providing much-needed extra space – especially if you don’t want to move house but have outgrown your current property.

Extensions also add value to your house. An extra bedroom, an additional bathroom or simply maximising your living space can make the resale value of your property sky rocket. It really is a great investment, especially if you ask the experts to undertake the work.

Ask us about the extension projects we have completed in the past. We are very proud of the extensions we have built for our previous customers and would be happy to show you images of the finished work.

Kayley Day

Just had Tom for a building project. We added a lot more work than originally planned and ended up removing walls and boxing in an open staircase. He has been brilliant. Nothing was too much trouble. Just waiting for plastering to dry out which is looking as smooth as a baby’s bum. So I can honestly say we are extremely pleased with everything.
