Who a porch extension suits
- 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.
Extensions in and around Herne Bay
We cover Herne Bay and the postcode districts CT6. We also work in nearby Whitstable (5 miles), Canterbury (7 miles), Faversham (11 miles), Margate (11 miles).
For homes towards Essex, Southend-on-Sea is around 21 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Planning and approvals in Herne Bay
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.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
