What to know before a replacement block drive in Dorchester
In and around Dorchester, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
The South West is wetter than the east of England, so falls and drainage are planned before the pattern is chosen.

What is included?
Replacing an old drive with block paving means breaking out the existing tarmac, concrete or gravel, checking what is underneath, and then building a block drive on a sound base. Many older tarmac and concrete drives have cracked, sunk or broken up, which is why this is such a common way into block paving.
- Levels set below the damp-proof course with falls away from the house
- New edging, sub-base where needed, and the block drive
- Drainage added where the old drive sent water to the house or road
- Assessment of the old base: keep, top up or replace
- Break-out of the old surface with waste removal and skip or grab lorry
What the survey covers
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Edges against lawns, beds, walls and neighbours
- Whether front-garden planning rules apply
- Ground conditions under the old surface and how deep the sub-base must be
- Trees and roots near the drive
Rules for front drives in Dorchester
Dorchester 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.
