Building in a large rear garden in Llanelli

If your back garden in Llanelli runs well past the patio and the lawn you actually use, the far end might be a building plot. Whether it is depends on four things: depth, a safe way in, what sits around it, and how a new home would affect the neighbours.

Backland Development looks at gardens like yours for free. If it looks workable, you can sell the plot and keep living in your house, or keep the land and have us design, get planning for and build a new home there. We’re a new brand within the S&K Group, and we’ll tell you straight if your garden isn’t a plot.

Llanelli: light, access and policy

Access is where many garden schemes succeed or fail, in Llanelli as anywhere. A drive squeezed past the side of a house has to be wide enough for cars, give drivers a clear view as they pull out, and keep noise and headlights from bothering the people next door. A new or wider dropped kerb also needs the highway authority’s consent.

Homes in SA15 with a garage or a wide side passage often start ahead here. Where the gap is tight, a smaller home, a shared drive with a neighbour or access from a lane behind may still work. Because Carmarthenshire County Council will look closely at the detail, we design the access before the house.

This section is worked out for the latitude of Llanelli: around 38° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

How we’d take it forward in Llanelli

Send us your address in Llanelli and a rough idea of what you’d like. We check the planning history around you and the policies Carmarthenshire County Council applies, and look for anything in the title that could get in the way. If the garden passes those checks, we arrange a visit at a time that suits you and explain each route in plain terms.

  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.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Questions about garden plots in Llanelli

Does it cost anything to have my Llanelli 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.

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

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.

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

Carmarthenshire County 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.

How do I find out if my Llanelli 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.
