The attic can be transformed in an ultimately cozy livin space where family & friends can spend time together and have fun together.

South West London Attic Living Space


The dormer loft conversion we provide is an extension of the existing roof, that protrudes vertically from a downlard sloping roof. This creates additional floor space and head height within the loft area.



Because a roof light conversion is not considered to overlook neighbours properties, you don't usually have to apply for planning permission this cuts out alot of the planning paperwork. With this type of conversion Velux windows is the prime choice for slanted roof glazing.



APT's Hip to Gable extension expands the hip of your existing roof through to the Gable end. This type of loft conversion gives greater roof space and also enables a larger rear dormer to be constructed maximising your interior space. This style is most popular in semi-detached houses.

Once a Truss roof lofts has been converted, they usually offer a larger more spacious room than traditional gabled roofs, thus they add that much more ambient space around your loft.



If you need a loft conversion, and your existing attic space doesn’t have the headroom, then a roof lift is the answer. A roof lift raise conversion is where the ridge line of your existing roof is raised by constructing a new roof to the right height and pitch to increase the room height.
