How we can help

  • Dormer, mansard and rooflight conversions
  • Structure, stairs and weatherproofing
  • Loft bedrooms, studies and bathrooms

How pricing works

Price is set by the roof form, the structure the new floor needs, the stairs and any bathroom. A dormer, a mansard and a rooflight scheme are different scopes. The written scope separates structure, weatherproofing and fit-out and notes which parts depend on consents.

Your next step

Send the postcode and photographs from the loft hatch and of the roof from the street. If you can measure it safely, add the height from loft floor to ridge. Say which drawings or consents you hold. We will confirm availability and whether a survey is needed before quoting.

Loft conversions in Hampstead, tested against roof and consent

A loft conversion in Hampstead depends on the roof you already have. Pitch, height, structure and the condition of coverings, parapets and chimneys all shape what is possible. In a converted house or a block, the roof may not belong to the flat below it at all. Some roofs have been altered before. We start with a measured survey and a look at the existing structure, so the design responds to evidence rather than an assumed standard layout.

Consent for a loft conversion needs care. If a house is in a conservation area, a roof extension will generally need planning permission rather than relying on permitted development. Camden’s Article 4 schedules should also be checked for the property, and listed status confirmed. Building Regulations cover structure, stairs and fire safety as a separate matter. Steel beams bearing on a party wall can engage the Party Wall etc. Act. Every point is settled for the exact address before design is fixed.

Loft work in Hampstead brings scaffold, long timbers and steel to what is often an occupied house. Slopes, narrow routes and controlled parking affect the scaffold footprint, loading and any licence or parking suspension, which is checked with the relevant authority. Materials may need to come up through the house or over the roof. We plan that route early, protect stairs and landings, and keep dust away from the rooms below.

Tell us what the new space is for, such as a bedroom, study or bathroom, and how much headroom matters to you. Share any drawings, earlier consents and photographs of the loft and roof. For a flat, include the freeholder’s details. Hampstead Renovations then prepares the scope with you, covering design stages, approvals, structure and finishes. The written scope shows what depends on consent, and our own team carries out the build once it is agreed.

Which loft conversions suit your Hampstead roof?

A rooflight conversion keeps the existing roof shape, so the loft needs enough height under the ridge to work as a room. A dormer, mansard or hip-to-gable adds headroom and floor area by changing the roof. Measure floor to ridge where it is safe, and note where the chimneys run.

The stair to the new room takes space from the floor below, so note which landing or bedroom it could use. New steel beams set into a shared wall can bring in party wall notices. The structure may need a site visit, not just photographs.

Consents depend on the exact address. Camden’s design guide says a street-facing rooflight in the Hampstead Conservation Area needs planning permission. Permitted development for a dormer or hip-to-gable does not apply to flats or to houses in a conservation area. The conversion also needs Building Regulations approval.
