Driveway extensions and widening across Devon
A driveway extension adds new hard-standing to an existing drive, usually by taking in part of the front garden, so more cars can park off the road. The new area needs its own excavation and base, and the whole drive is often resurfaced in resin so old and new match.
If the extension means cars will cross the pavement in a new place, the dropped kerb has to be widened or a new one added, and that needs consent from the highway authority (your council, or DfI Roads in Northern Ireland). We price the drive and help with the application, but the kerb work itself is carried out by that authority or its approved contractor.
In Plymouth we can price work such as adding a channel drain where a drive falls towards the garage, replacing tired block paving with a permeable resin build and framing a golden blend with charcoal granite setts.
Prices in Devon
For the South West, where typical costs are above the UK average, these are the ranges we would expect before seeing your property.
Driveway extensions and widening: £80–£130 per m².
For a 64 m² drive in Devon, built with a dig-out and new permeable base, expect roughly £5,150–£8,200 including VAT before any drainage or kerb work.
Planning in Devon
In England, a new or replaced hard surface of more than 5 m² in a front garden is permitted development only if it is porous, or if rainwater drains to a lawn, border or soakaway within the property. A fully permeable resin bound build, with a porous base under it, meets that test.
Permitted development rights apply to houses, not flats or maisonettes, and some conservation areas have Article 4 directions that remove them. Listed buildings can need consent if railings or historic walls are affected.
If cars will cross the pavement in a new place, or the crossing needs widening, consent is needed from your council as local highway authority before any kerb work.
Weather and working days
The South West gets more rain than the east of England, especially on higher ground, so permeability and falls matter on every drive. Spring to autumn offers the most laying days in Devon, but dry, mild winter days can work too.
Driveway extensions and widening in Devon: questions
Is the price fixed for Devon jobs?
Yes, once the scope and specification are agreed in writing. If hidden ground conditions turn up, we explain and agree any change with you before doing extra work.
Do I need planning permission in Devon?
In England, a new or replaced hard surface of more than 5 m² in a front garden is permitted development only if it is porous, or if rainwater drains to a lawn, border or soakaway within the property. A fully permeable resin bound build, with a porous base under it, meets that test.
Can you lay resin in Devon in winter?
On dry days with ground and air above about 5°C, yes. The South West gets more rain than the east of England, especially on higher ground, so permeability and falls matter on every drive.
