What goes into a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Design, planning drawings and structural calculations
- Party wall process with both neighbours if needed
- Glazing, insulation, plastering and electrics
How much should I budget for a wraparound extension?
Indicative costs for wraparound extensions. London and the South East usually sit towards the top of each range.
| Wraparound extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,400 to £3,800 per m² |
| Good specification | £3,800 to £4,250 per m² |
| High specification | £4,250 to £4,700 per m² |
How is a wraparound extension approved in Penrith?
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 wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development. Most need householder planning permission, which usually takes around eight weeks once validated.
What can change the price or programme?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- An open-plan space this size needs a heating plan, often underfloor heating.
From first call to completion

Wraparound extensions: common questions
How long does a wraparound take?
Around 12 to 18 weeks on site after approvals.
Glazed roof or solid roof?
A mix usually works best: solid roof with rooflights over the kitchen and a glazed section over the dining area.
Can you visit a house in Penrith 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.
