Covering Littlehampton

We work in Littlehampton (BN17) and the places around it, including Bognor Regis, Worthing and Chichester.

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 is included in a side return extension in Littlehampton?

A side return extension builds over the narrow passage that runs beside the back of many Victorian and Edwardian terraced houses, widening the kitchen or dining room by a metre or two. It is usually combined with a glazed or part-glazed roof so the deeper room still gets daylight.

  • Party wall notices and surveyor liaison
  • Underfloor heating ready screed if wanted
  • Plastering and making good to the old house

Do you need permission for a side return extension in Littlehampton?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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.

What can change the price or programme?

  • Glazed roofs need careful detailing against the neighbour’s wall.
  • Many terraces sit in conservation areas, where side extensions need planning permission.

What are the steps?

  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.

Side return extensions: common questions

Does a side return need planning permission?

In England it can be permitted development if it is single storey, no higher than 4 m and no wider than half the original house. Conservation areas are the main exception.

Will I need a party wall agreement?

Most likely, because the new wall usually sits on or near the boundary. We serve the notices and work with your neighbour’s surveyor if one is appointed.

Who deals with the council for a project in Littlehampton?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
