GMB were commisioned to build this new luxury 4,500 sq ft building in Horsham. Work commenced in January 2018 and the project is now well on target to be completed in November 2018 despite the awful wet weather we experienced early this year.

New build in Wineham Lane, Nr Henfield.

This was a four bedroom house we built with an office outbuilding and an oak framed double garage. It is a sustainable home and very modern inside. It contains lots of big windows so the house is very light inside and in the roof there is a large master bedroom with walk in wardrobe and en-suite.
