HIP-TO-GABLE LOFT CONVERSION in LONDON
Explore the benefits of adding a hip-to-gable loft conversion to your London property.
1
What Is a Hip-to-Gable Loft Conversion?
A hipped roof has sloping sides that meet at a ridge — unlike a gable roof where the end wall rises vertically to the apex. On a semi-detached house, the hipped end is typically on the side that faces away from the adjoining property.
2
Which Properties Suit a Hip-to-Gable Conversion?
Hip-to-gable conversions are designed specifically for semi-detached and detached houses with hipped roofs — the property type that dominates Ealing's W5, large parts of Chiswick W4, and the broader Edwardian residential stock across West London. They're not applicable to mid-terrace properties, which typically have gable ends already.

Planning Considerations for Hip-to-Gable Conversions
Hip-to-gable conversions on semi-detached houses fall within permitted development in most cases, provided the total volume added doesn't exceed the 50 cubic metre limit that applies to semis. The gable wall itself is on the side of the property, not the rear, which means it's visible from the street on corner plots — this can bring it into greater planning scrutiny. Conservation area designations, which apply to significant parts of NW3, NW1 and parts of SW London, may also restrict the external changes permitted.

What Does a Hip-to-Gable Loft Conversion Cost in London?
Hip-to-gable conversions in London typically range from £50,000 to £80,000, reflecting the additional structural work involved in rebuilding the gable end compared to a standard dormer. When combined with a rear dormer - which is the norm - the project is more involved but the resulting space addition is substantially greater.
TYPES OF LOFT CONVERSIONS
Dormer Loft Conversion
A dormer is a structural extension that projects vertically from the existing roof slope, creating a box-shaped addition with a flat or pitched roof.
Hip-To-Gable Loft Conversion
A hipped roof has sloping sides that meet at a ridge — unlike a gable roof where the end wall rises vertically to the apex.
Mansard Loft Conversion
A mansard conversion involves replacing the existing rear roof slope with a near-vertical wall - typically at 72 degrees - topped by a shallow flat roof.
