What is a porch?
A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.

Do you need planning permission for a porch in Horsham?
Here is how the rules work for a porch in England. In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is over 3 metres high and it is at least 2 metres from a boundary next to a road.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
On a typical porch we handle:
- Roof and guttering
- Front door and windows

- Plastering and decoration
- Design to match the house
- Foundations and brickwork
How long does it take?
Expect 2 to 4 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.

Meters belong to the supplier or network operator. We coordinate their move as part of the job, which can add time.
Will it match my house?
We source matching bricks and tiles where possible, or suggest a deliberate contrast.
