Building plots in large rear gardens in South Glamorgan

Where several long gardens sit side by side in South Glamorgan, owners sometimes get a better scheme by working together than by going it alone. One shared drive can serve new homes across two or three gardens, leaving each existing house with more of its garden and fewer cars passing its windows.

That isn’t the only way forward. A single long garden with a good access can work on its own, and some owners would rather keep the land and have a home built for a relative. We assess your plot first, then talk through selling, partnering with neighbours or building, so you can decide with the facts in front of you.

How councils in South Glamorgan look at it

Old titles can hold surprises, and gardens in South Glamorgan are no exception. A restrictive covenant may limit building, a mortgage lender must agree to release the plot, and a strip of land you don’t own can sit between your garden and the lane behind it. Trees in a conservation area or under a Tree Preservation Order need consent or notice before any work. We read the title documents as part of the appraisal, so problems come to light before you spend money on design rather than after it.

Planning authorities covering South Glamorgan include Cardiff Council, Vale of Glamorgan Council.

How it works

  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. Planning application

    We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.

  5. 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.

Questions about large rear gardens in South Glamorgan

Do you look at large rear gardens in South Glamorgan?

Yes. We cover the whole of South Glamorgan, as part of our coverage across England and Wales. Send us your address and a few details about your garden, and we’ll carry out a free desktop appraisal before suggesting a site visit.

What fire and drainage rules apply to garden homes in South Glamorgan?

Every new home must allow for sprinklers, which every new home in Wales must have. On drainage, expect approval from the SuDS Approval Body (SAB) before building starts. Both can affect where a home sits in a long garden and how the drive is laid out, so we check them early rather than after the design is drawn.

Do I have to sell, or will you build on my land in South Glamorgan?

Either works. On the selling side there’s an outright sale, a sale subject to planning, an option, or a planning promotion on bigger or combined gardens. On the building side, you keep the land and we take a new home from design through planning to handover. A free appraisal comes first.

Can you build a new home in my garden in South Glamorgan for me to keep?

Yes. Through our design and build route we survey your plot, design a new home with you, apply for planning and, once permission is granted, build it. You keep the land and the new home, to sell, let or use for family. You get a written quote after design and survey, and any earlier guide price is a guide only.
