Homes in the East of England

Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.

What is a side return extension?

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.

  • Glazed or solid roof with rooflights
  • Drainage and new gully positions
  • Underfloor heating ready screed if wanted

How is a side return extension approved in Bedfordshire?

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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.

What can change the price or programme?

  • Access is often through the house, so we plan deliveries and protect floors.
  • Glazed roofs need careful detailing against the neighbour’s wall.

From first call to completion

Your questions answered

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.

How long does a side return take?

About 10 to 14 weeks on site.

Can you visit a house in Bedfordshire 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.
