Planning a driveway extension in Seaford
In and around Seaford, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
Chalk, clay and sandy ground all occur across the South East, so the dig and sub-base depth are set on the survey rather than assumed.
How much does a driveway extension cost in Seaford?
Guide price in Seaford: £95–£160 per m² including VAT, which puts a 15 m² extension at about £1,700–£2,800. These are South East guide figures; the survey confirms the real price before you commit.

What is included?
A driveway extension adds paving to an existing drive, usually to fit a second car by taking in part of the front lawn, or to lengthen a drive towards the house or garage. The new section is built on its own sub-base and tied into the old paving so the two act as one surface.
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Matching options: same range, re-mixing old and new, or a planned contrast
- Check of the existing drive: block range, thickness, levels and condition
- Dig-out and sub-base for the new area
- Joint sand, compaction and a clean-down of the old section
Before we price your driveway extension
- Whether front-garden planning rules apply
- Edges against lawns, beds, walls and neighbours
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Where rain will go: falls, lawn, border, channel or soakaway
- Steps, thresholds and door heights
Planning and kerb rules in Seaford
Seaford is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
