The local picture in Rhondda
Take a walk round the junctions near you, in Rhondda and in Mountain Ash, Aberdare and Pontypridd. Side gardens that already have a house on them show the kind of thing the council has accepted before, although each new application stands on its own and is judged under today’s policy. A corner that is still open will draw closer attention.
Those local tests are written into the council’s Local Development Plan (LDP) and any design guidance Rhondda Cynon Taf County Borough Council has adopted. Reading both before we draw means the scheme already answers the points an officer is likely to raise.
How we’d take it forward in Rhondda
Give us your Rhondda address and a sense of what you’re hoping for. Our desktop review covers the policies Rhondda Cynon Taf County Borough Council works to, recent applications on nearby side and corner plots, and anything in your title that might restrict building. A clear result leads to a visit when it suits you, after which we explain each route and what it would mean in practice.
Free plot appraisal
We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.
Read the street
We measure the plot and record the building line, the gaps between houses, roof heights, materials and boundary walls, then check where a new drive could go and what drivers would be able to see from it.
Choose your route
Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.
Sale or build
For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.
Worth checking early
- A new drive close to a junction may not be acceptable to the highway authority, which can force a different layout.
- The council decides, and neighbours are consulted; a sensible design can still be refused or need changes.
- Corners kept open by design can be harder to build on than they look; character can matter more than space.
Questions about garden plots in Rhondda
Could I sell just my side garden in Rhondda and stay put?
Yes. Legally it’s a transfer of part: HM Land Registry gives the side plot a title of its own, while your house keeps the rest. A mortgage lender has to consent to releasing the plot from its charge. Where the plot suits, we buy with or without planning, subject to survey, title and contract.
Can I attach a new home to my house in Rhondda?
Yes, where it suits the street, for example on the end of a semi-detached pair. It needs planning permission as a separate home, fire and sound separation under Building Regulations, and possibly a party wall agreement. We check whether attached or detached fits your road better.
Can you build a home beside my house in Rhondda for my family?
Yes. A home next door can give a parent or grown-up child their own front door while keeping them close. You keep the land; we draw the house, apply for permission, build it and arrange the structural warranty or other cover lenders accept. The written quote comes after design and survey.
Is my Rhondda side garden wide enough for a new house?
It depends on how wide homes are in your street, the gaps between them, whether the new home would be attached or detached and what the council’s design guidance says. There’s no single minimum width. We measure your plot and the street as part of a free appraisal.
