Rules that apply in Carmarthen

In Wales, a new hard surface in front of a house is permitted development only if it is porous or drains to a permeable area within the property; repairing or replacing up to 5 m² of existing hardstanding is allowed without meeting that condition. Separately, since January 2019, construction covering 100 m² or more that affects drainage generally needs approval from the council's SuDS Approving Body (SAB) before work starts, even where planning permission is not needed. Larger drives, shared surfaces and car parks often reach that threshold. If the job needs a dropped kerb, the council as highway authority approves it before any work on the footway.

What the price covers

A front garden conversion turns lawn or planting into a parking space: the ground is excavated, a stone sub-base laid, tarmac surfaced on top, and a lowered kerb arranged so a car can cross the pavement legally.

Check the space: length, width and gate posts for a car
Highway authority dropped kerb application guided or handled for you
Lawn, hedge roots and topsoil removed
Sub-base and two tarmac courses, or porous asphalt
A planted strip kept where it helps drainage and looks
