What driveway extensions and widening involves
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.
Any quote we prepare in Cardiff says which base route we recommend and why, with the depth, the resin and the aggregate written down. Housing in Cardiff ranges from Victorian terraces to post-war semis and newer estates, and drive sizes vary just as much.
In Cardiff we can price work such as overlaying sound tarmac on a two-car drive, replacing tired block paving with a permeable resin build and framing a golden blend with charcoal granite setts. More about driveway extensions and widening.

Planning in Cardiff
Wales has its own permitted development rules on the same principle: a front-garden hard surface should be porous or drain to a permeable area on the property. A fully permeable resin bound build, with a porous base under it, meets that test.
In Wales, new construction with drainage implications covering 100 m² or more can also need approval from the council's SuDS Approving Body (SAB). Most domestic drives are smaller than that, but larger drives and extensions are checked at survey.
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.
General information for Wales, not legal advice.
Weather and working days
South Wales is wetter than most of England, so a permeable build or a planned route for water is essential on every drive. If the weather turns on the day, we move the pour rather than risk a surface that will not cure.
