Most end-of-terrace, semi-detached and detached houses have traditionally been built with a hipped style roof. This is where the roof slopes in at the side and will restrict the loft space. By changing the roof slope from a hip to a gable end, where the wall is built up vertically, we can extend the roof across to its full width and with the addition of a rear dormer, the loft space is fully extended.

On occasion, our clients request that both sloping sides of the roof for a detached house be straightened (a ‘double hip to gable’). Whether you require this type of attic conversion depends on your property and style of roof, but this has the added benefit of creating a much larger attic space. Hip to gable conversions can also be used to extend an existing loft conversion, and this has the advantage of creating additional room, such as an en-suite bathroom or walk-in wardrobe or dressing room.

Although this involves a major structural change to a roof, in many cases, planning permission isn’t required for a hip-to-gable loft conversion; however, this is not always the case, particularly if the building lies in a protected zone such as a conservation area. At Tangram Projects, we submit planning applications as and when required and provide regular updates for our clients.
