Hip to Gable Loft Conversion

Hip to gable conversions are increasing in popularity as they offer a more seamless look than the “boxy” appearance and contrasting angular design of a dormer loft conversion. Hip to gable conversions are great for maximising the space of properties with three sloping sides – i.e.- hipped roofs, perfect for a master bedroom or en-suite addition.

Hip to Gable conversions are suited to semi-detached and detached properties which more often have hipped roofs which would be extended outwards and connected to a new vertical wall creating a triangular face called the gable end.

Due to the required extension of the roof line to form the new gable end, planning permission may be required. Local Builder London’s team of architectural designers and builders have mastered the construction of hip to gable conversions for properties in and across London, Greater London and the Home Counties – our proven track record means you can be truly confident in our consultation and quality of build. You can expect a conversion which seamlessly blends in with the style of your property and refreshes both its look and value.

  • A hip to gable loft conversion is a type of conversion that can only be executed in a property which has a hipped roof – a roof with more than two sloping sides.
  • Unlike dormer loft conversions, these are more likely to require planning permission as they require considerably significant structural changes to the roof line.
  • It also offers more space than a hip-ended or side dormer because it extends all the way to the outer wall of the house.
