Mansard loft conversions in Eastbourne

Homeowners in Eastbourne can get mansard loft conversions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Eastbourne

Eastbourne is about 19 miles east of Brighton. We also cover Hailsham (7 miles to the north), Seaford and Bexhill-on-Sea.

Homes in the South East

Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.

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
  • Slate cladding and lead-clad dormers
  • En-suite, electrics and fire safety

What approvals does a mansard loft conversion need in England?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

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

What should Eastbourne homeowners check first?

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

What are the steps?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
