Covering Isleworth
Our coverage around Isleworth (TW7) also includes Hounslow (1 miles to the south-west) and Heston.
Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
What do you get with a porch?
A porch is a small enclosed entrance built in front of the front door, giving somewhere for coats and shoes and a buffer against draughts. Many porches are small enough to be built without a planning application.
- Foundations and matching brickwork
- Lighting and power
- Plastering and flooring ready finish
How much should I budget for a porch?
Indicative costs for porches. London and the South East usually sit towards the top of each range.
| Porches | Guide price incl. VAT |
|---|---|
| Open canopy over the door | £2,500 to £5,000 |
| Brick porch with tiled roof | £6,000 to £10,000 |
| Larger porch or front extension | £10,000 to £16,000 |
Planning and building rules in Isleworth
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 porch is permitted development if its footprint is no more than 3 m² measured externally, no part is higher than 3 m, and no part is within 2 m of a boundary with a road or footpath. Larger porches need planning permission.
What can affect a porch?
- Keeping the original front door between house and porch can keep a porch exempt from building regulations.
- The roof pitch should echo the main roof or bay window.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

How long does it take?
One to three weeks on site.
Can a porch include a toilet?
Yes, but it becomes a front extension, which usually needs planning permission and building regulations approval.
Can you visit a house in Isleworth 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.
