Covering Enfield
We work in Enfield (EN1, EN2) and the places around it, including Edmonton, Tottenham and Wood Green.
Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
What goes into a single-storey extension?
A single-storey extension adds one level of new floor space to the back or side of a house, usually to open up a kitchen, dining or family room. It is the most common way to gain space without moving, and many can be built without a planning application.
- Foundations, drainage and structural steel
- Brickwork, roof, glazing and insulation
- First-fix and second-fix electrics, plastering and making good
How much does a single-storey extension cost in Enfield?
Guide prices for single-storey extensions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| Single-storey extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £2,600 to £3,000 per m² |
| Good specification | £3,000 to £3,500 per m² |

What approvals does a single-storey extension need in England?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
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?
- Building on or near a shared boundary usually means serving a party wall notice in England and Wales.
- Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
Can we stay in the house during the build?
Usually yes. We keep the existing house closed off from the works until the knock-through near the end, and agree a temporary kitchen set-up with you if the kitchen is affected.
Will the brick match?
We source the closest available match for colour, size and texture and agree a sample panel with you before laying.
Can you visit a house in Enfield 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.
