Mansard loft conversions in Gravesend

We take on mansard loft conversions in Gravesend as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Gravesend

Gravesend is about 14 miles north-west of Maidstone. We also cover Grays (3 miles to the north-west), Strood and South Ockendon.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

What does a mansard loft conversion involve?

A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.

  • Roof removal and new mansard frame
  • Staircase, insulation and fit-out
  • En-suite, electrics and fire safety

Planning and building rules in Gravesend

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.

Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.

What can affect a mansard loft conversion?

  • A mansard nearly always involves party walls on both sides of a terrace.
  • Council design guides often require natural slate and lead.

How does the project run?

  1. Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
