Building in a large rear garden in Rhondda

If you have a long rear garden in Rhondda, the first question is usually the obvious one: is there really room for a house down there? The honest answer comes from measuring, not guessing. Separation from existing back windows, garden space for both homes and a drive that works for cars, bins and emergency access all have to fit.

Once we know what could realistically go there, you pick the route that suits you. Some owners prefer a clean sale of the plot, with or without planning. Others want the new home itself, for a parent, a grown-up child or to let. We handle the design and the planning application either way.

What the council will look at in Rhondda

Every application for a new home in a Rhondda back garden is decided by Rhondda Cynon Taf County Borough Council, which weighs it against the council’s Local Development Plan (LDP), national policy and any local design guidance it has adopted. Those documents often set out separation distances, minimum garden sizes and how homes behind the street should relate to it.

We read the relevant policies for your address before suggesting a layout, and where it helps we ask the council for pre-application advice. That way the scheme you see reflects what is likely to be acceptable locally, not a generic drawing.

How we’d take it forward in Rhondda

Once you’ve had the free appraisal, nothing moves without your say-so. For a sale, terms are agreed in writing before you sign anything. For a build, design and survey come first and the quote follows. In both cases the planning application goes to Rhondda Cynon Taf County Borough Council, which consults your neighbours before deciding. Small schemes often take a few months from submission, and surveys or design changes can add more.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. Choose your route

    You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • A shorter garden changes how your own house feels to live in and may affect what it is worth.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.

Rhondda: questions to ask

How do I find out if my Rhondda garden is big enough for a house?

Ask for a free garden plot appraisal. We measure depth and the width of the way in, check what lies behind, look at levels, trees and drainage, and compare your garden with your council’s separation and garden-size guidance. Size alone rarely settles it, because access and neighbours’ privacy matter just as much.

Does it cost anything to have my Rhondda garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.

Who decides planning for a home in a Rhondda back garden?

Rhondda Cynon Taf County Borough Council decides, using the council’s Local Development Plan (LDP), national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

Can you build a home for my family in my garden in Rhondda?

Yes. If you keep the land, we can design the home, apply for planning permission, build it once permission is granted and arrange the structural warranty lenders usually expect. You receive a written quote after design and survey. If the home is for a relative who will share your kitchen and front door, an annexe may suit better.
