The growing popularity of Basement Conversions

With house prices in many areas of the South of England at record levels, despite ongoing concerns with Brexit and Covid, and prohibitive moving costs, many homeowners are exploring the idea of building basements to increase valuable square footage and boost their property's value. Stamp duty land tax, estate agent fees and conveyancing fees means families are giving basement excavation and basement construction serious consideration. 

McGrath Civils have recently worked on basement excavation and construction projects in Oxford and Brighton, for clients adding valuable square footage to their properties and creating beautiful family spaces, including open plan kitchen diners, games rooms, cinema rooms and offices.

Our specialist basement services include:
