Covering Mitcham
Mitcham sits 7 miles south of London, with Morden 1 miles to the west and Wimbledon 2 miles to the north-west.
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 does a porch involve?
We build porches in matching brick with a tiled or lead roof, a new composite or timber door, and lighting. If you want a wider entrance or a WC, we can design a larger front extension instead and handle the planning.
- Design to match the house
- Lighting and power
- Plastering and flooring ready finish
How much does a porch cost in Mitcham?
Guide prices for porches, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| 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 |
What approvals does a porch need in England?
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 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 should Mitcham homeowners check first?
- Keeping the original front door between house and porch can keep a porch exempt from building regulations.
- Gas meters and drains near the front door may need relocating.
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.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

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 Mitcham 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.
