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.

In Portishead, a porch typically costs £6,750–£16,500 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate).

Do you need planning permission for a porch in Portishead?
Before anything is built in Portishead, we confirm which approvals apply 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

Questions about porches in Portishead
Do I need planning permission for a porch?
In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is higher than 3 metres and it is at least 2 metres from any boundary next to a road. Larger porches need an application.
Can you move the gas or electric meter?
Meters belong to the supplier or network operator. We coordinate their move as part of the job, which can add time.
Does a porch need building regulations?
In England and Wales a ground-level porch under 30 square metres is usually exempt if the front door stays in place and the glazing meets safety standards. In Scotland the exemption is much smaller (around 8 square metres, with no new opening into the house). If the front door is removed, approval is needed. We check this for your design.
