MAXIMISE THE PERMITTED VOLUME WITH A MASTER BEDROOM AND ENSUITE SHOWER ROOM: THE L-SHAPED DORMER
L-shaped dormers have become a popular way of utilising and maximising the available permitted allowances of 40 cubic metres for terraced houses and 50 cubic metres for semi-detached. Houses built in the Victorian or Edwardian periods with an outrigger or rear addition at the back up to first floor level lend themselves very well to this form of roof extension. They can result in a large master bedroom with ensuite and often providing enough space for two luxury bedrooms and a shared shower room.
