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 Marlow?
In Marlow, a porch typically costs £7,250–£18,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the South East run about 12% above the UK average, and the figures for Marlow are adjusted to reflect that. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £7,250–£18,000 |
| Higher specification | £18,000–£22,500 |
The biggest cost drivers are:
- Brick matching
- Size and roof style
- Whether building regulations apply
- Moving meters, drains or the doorbell and lighting
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a porch in Marlow?
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.
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.
