What decides whether a site in South Glamorgan works
Character of the street
New homes need to suit the building line, height and spacing of the street.
Neighbours' amenity
Overlooking, loss of light and outlook are the issues planners weigh most often.
Trees
Protected trees or trees in a conservation area can limit what fits.
The Planning (Wales) Act 2026 received Royal Assent on 27 April 2026 and is being brought into force in stages, consolidating Welsh planning law into a single Welsh framework.
In parts of Wales where Welsh is widely spoken, councils may consider the effect of new housing on the Welsh language when preparing plans and deciding applications.
