This extension has been fitted with a cantilever roof system enabling our bi fold doors to slide in two directions with the addition of a removable corner post. Our floating corner post system means that the whole aperture can open up leaving no obstruction between the room and the garden. Created using a RAL colour 7015 (slate grey) and a marine grade finish ( due to proximity of the doors to the Solent ), these doors are fitted with a recessed track to achieve a virtual flush finish.
