Planning and approvals in Gravesend
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).
When a porch extension makes sense
- Busy hallways with no storage
- Front doors that open straight into a living room
- Homes wanting better kerb appeal
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
