The types of loft conversion that APT Build

ATTIC FLOOR EXPANSION

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

DORMER LOFT CONVERSION

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.

ROOF LIGHT CONVERSION

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.

HIP TO GABLE

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.

TRUSS LOFTS

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.

ROOF LIFT/ ADDIONAL FLOOR

If you need a loft conversion, and your existing attic space doesn’t have the headroom, then a roof lift is the answer. APT Can either perform a roof lift where we raise the ridge line of your existing roof, or we can constructing a whole new floor. These types of structural changes are subject to Planning Permission.

Reviews
APT remodelled my entire house to an excellent finish. They added a rear and side double storey extension. They were fantastic I am extremely happy with the result. They stuck to the time frame we agreed and were very helpful with ideas. Angus the site manager was hard working. I have recommended APT to some of my friends who are looking to do similar projects. We will be having our loft done at some point so we will for sure use APT again. Loft Conversion Build
