Hip to Gable Loft Conversions

These loft conversions can only be performed in semi-detached and detached houses, and are therefore quite rare in Central London. However, they are sometimes an option for end-of-terrace houses.

Hip to Gable conversions involve changing the shape of the roof, which means that it may require planning permission. Hipped roofs have angled sides, so the corners have been cut off both ends. Changing this to a Gabled roof involves extending the sides of the roof and ensuring that the sides are completely vertical, rather than angling inwards – this provides additional headroom and can be particularly useful if your staircase is built at the very end of your loft conversion.

Combined Loft Conversion Types

Unlike Velux or Dormer loft conversions, this loft conversion classification doesn’t refer to the addition of windows onto the roof. As a result, most Hip to Gable loft conversions are actually a blend of different loft conversion types, depending on whether you prefer to add Dormer windows or roofline windows to the design.


Planning Permission

Planning consent requirements depend on your area, your house type, and whether the house has already been altered. While many loft conversions can be completed as permitted developments, there is a limit on the number of permitted developments allowed per house, so if you have already added an extension onto your home or altered it in any other way you may require planning permission for your loft conversion.

However, Hip to Gable loft conversions do make extensive changes to the exterior of your house, so in built up areas and in conservation areas they may require planning permission. We work with a number of architectural partners to ensure that your designs fit your needs, and to sort through the bureaucracy surrounding loft conversions. Our architects will apply for planning permission on your behalf – if necessary – and ensure that your building work meets all of the requirements for your area.
