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 goes into 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 South Benfleet?

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 should South Benfleet homeowners check first?

  • Most side returns touch a shared boundary, so the Party Wall etc. Act 1996 usually applies in England and Wales.
  • Access is often through the house, so we plan deliveries and protect floors.
