Hip-to-gable loft conversions in Notting Hill

Homeowners in Notting Hill can get hip-to-gable loft conversions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Notting Hill

We work in Notting Hill (W11) and the places around it, including Shepherd's Bush, Willesden and Fulham.

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?

Hipped roofs are common on 1930s semis and have little usable volume until the hip is squared off. We rebuild the gable in brick or block, extend the roof structure, form the rear dormer and finish the new floor, keeping the front roof slope looking as close to the original as possible.

  • Rear dormer and roof coverings to match
  • Staircase, insulation, plastering and electrics
  • En-suite and fire-protected escape route

How is a hip-to-gable loft conversion approved in Notting Hill?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

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 should I think about before starting?

  • Hip-to-gable volume counts towards the permitted development allowance.
  • Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.

How does the project run?

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
