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.
How much does a porch cost in Norfolk?
In Norfolk, a porch typically costs £7,000–£17,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). That range is adjusted for the East of England, where domestic building work typically costs around 6% above the national average. Design, structural calculations and council fees are extra.

|---|---|
| From a 3 m² porch to a small front extension | £7,000–£17,000 |
| Higher specification | £17,000–£21,000 |

- Front door specification

Do you need planning permission for a porch in Norfolk?
Whether you need planning permission depends on your house and its location 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

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.
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.
