Loft conversions in Eastbourne

Loft conversions for homes in Eastbourne and the surrounding parts of East Sussex, designed around your house and built by our teams under a single written contract.

Covering Eastbourne

We work in Eastbourne (BN21) and the places around it, including Hailsham, 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 do you get with a loft conversion?

We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.

  • Planning or lawful development certificate
  • Dormer or rooflights, insulation and plasterboard
  • En-suite, electrics, heating and fire safety upgrades

What will a loft conversion cost?

Typical ranges for loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Planning and building rules in Eastbourne

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.

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 loft conversion?

  • Head height under the ridge decides whether a conversion is practical.
  • Fire safety rules can mean new fire doors on the floors below.

What happens after I enquire?

  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. 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.

Your questions answered

Does a loft conversion need planning permission?

In England many are permitted development, within 40 m³ of extra volume on a terrace or 50 m³ on a semi or detached house. Conservation areas and flats need permission.

Can we live at home during a loft conversion?

Yes. Most of the work is done from scaffolding until the staircase goes in near the end.

Can you visit a house in Eastbourne to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
