How it is built

Planning and kerb rules for Treharris

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. A vehicle crossing over the footway is a separate approval, from the council as highway authority.
