Homes in London
Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.
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.
- Design to match the house
- Tiled, slate or lead roof
- Plastering and flooring ready finish
What will a porch cost?

| Open canopy over the door | £2,500 to £5,000 |
| Brick porch with tiled roof | £6,000 to £10,000 |

How is a porch approved in Carshalton?
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 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 Carshalton 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.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
