Single-storey extensions in Bognor Regis

Planning single-storey extensions in Bognor Regis? We design and build them for houses across West Sussex, and we fix the price for the agreed specification in writing before any building work starts.

Covering Bognor Regis

Bognor Regis is about 31 miles south-west of Crawley. We also cover Chichester (6 miles to the north-west), Littlehampton and Worthing.

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 single-storey extension?

We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.

  • Planning or lawful development certificate where needed
  • Foundations, drainage and structural steel
  • Brickwork, roof, glazing and insulation

Do you need permission for a single-storey extension in Bognor Regis?

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 a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What can change the price or programme?

  • Drains under the footprint may need diverting or a build-over agreement with the water company.
  • Building on or near a shared boundary usually means serving a party wall notice in England and Wales.

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. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
