What you get in South Glamorgan
Self-builder or developer
Some infill plots suit individual self-builders, while others suit a developer building several homes. We explain who is likely to want your plot and what that means for the deal.
Party walls and boundaries
Building on or near a shared boundary can trigger party wall procedures in England and Wales. Clear boundaries on the title plan help avoid disputes with neighbours later on.
Neighbours' light and privacy
Window positions, outlook and daylight to neighbouring homes are tested in planning. We look at how a design could protect them, because this often decides whether infill is approved.
Village infill policies
Some rural policies allow limited infilling within villages even where wider development is restricted. We check whether your plot falls within the exact wording of those rules.
Planning and land rules in South Glamorgan
Permission in Principle is not available in Wales, so the usual first step for land near South Glamorgan is an outline planning application, with reserved matters to follow, or a full application. Councils allocate housing sites through their Local Development Plan, and landowners can put land forward as a candidate site when a plan is prepared or reviewed. If your land is not allocated, an option or promotion agreement lets a partner take on the cost of promoting it.
In Wales, infill is judged against the Local Development Plan, which may define settlement boundaries or allow small rural infill sites under its own criteria. A single new home may still need approval from the SuDS approving body, depending on the construction area. Party wall procedures apply, as in England, and buyers pay Land Transaction Tax.

Your questions answered for South Glamorgan
How small can a plot be for a new house?
There is no single minimum. It depends on the width of the frontage, the size of neighbouring plots, space standards for the new home, garden and parking requirements, and how the design fits the street. A narrow plot may still work for a terraced design that continues an existing row.
Do my neighbours have a say if I sell an infill plot?
You do not need their permission to sell, but they will be notified when a planning application is made and can comment on it. Early, courteous contact often helps, especially if party walls, shared drives or boundary features such as hedges and fences are involved.
Is it easier to get planning permission for infill?
Often, because infill makes use of land within a settlement. But councils still refuse infill that harms the character of the street, neighbours' amenity or highway safety. In some rural areas, infill policies are tightly defined, so it pays to check the exact policy wording for your area.
Can I sell the side garden of my end-of-terrace house?
Often, yes, where the side garden is wide enough for a new home that continues the terrace or stands as a separate detached house. Consider the impact on your own home, parking and garden, and whether your mortgage lender will agree to release the land.
Is South Glamorgan an area you cover for land?
Yes, we cover land across South Glamorgan, including Barry, Penarth and Cardiff. Where a site suits us we can buy it directly, or set up an option or promotion agreement. On promotion there is nothing to pay upfront.
