Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What goes into a hip-to-gable loft conversion?

A hip-to-gable loft conversion rebuilds the sloping side (the hip) of a semi-detached or detached house roof as a vertical gable wall, extending the ridge and creating enough space for a staircase and rooms. It is usually combined with a rear dormer.

  • Volume calculation and planning check
  • Extended ridge and roof structure
  • Rear dormer and roof coverings to match

Do you need permission for a hip-to-gable loft conversion in Archway?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m.

What can affect a hip-to-gable loft conversion?

  • Matching old clay tiles can be difficult; reclaimed tiles are often used.
  • Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
