Block paved driveway extensions in Seaham: the local picture
Seaham is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
Former colliery ground and clay soils occur across the North East, so the survey checks for soft spots before the sub-base depth is set.

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.
- 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
- New edging, kerbs or a low retaining edge where the lawn is cut back
- Old edge restraint taken out and the new paving toothed into the old pattern
What the survey covers
- Block range, thickness, colour and pattern to suit the house
- Access for a mini-digger, skip or grab lorry
- Where rain will go: falls, lawn, border, channel or soakaway
- Whether front-garden planning rules apply
- The kerb: is it already dropped, and is it wide enough?
Rules for front drives in Seaham
Seaham 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.
