Building plots in large rear gardens in Gwynedd

A garden that once suited a young family can feel like a lot of lawn to mow later on. For owners in Gwynedd with a long rear garden, the far end might be put to better use as a building plot, though only a proper look at the site can say whether that’s realistic.

Backland Development was set up recently, as part of the S&K Group, to help homeowners turn spare garden land into new homes. You choose how involved you want to be. Sell the plot and stay where you are, or keep the land while we create a new home there for family, to let or to sell.

How councils in Gwynedd look at it

Old titles can hold surprises, and gardens in Gwynedd 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 Gwynedd include Gwynedd Council, Isle of Anglesey County 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 Gwynedd

What fire and drainage rules apply to garden homes in Gwynedd?

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.

Which councils decide garden plot applications in Gwynedd?

Applications go to the local planning authority for your address. Across Gwynedd, the authorities include Gwynedd Council and Isle of Anglesey County Council. Each works to its own development plan and design guidance, so the tests for a rear garden home can differ from one council to the next. We check the right ones for your plot.

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

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.

How much is a garden plot in Gwynedd worth?

It depends on location, size, access, title and, above all, planning. Two similar gardens in the same street can be worth very different amounts if one has easy access and the other doesn’t. We don’t quote figures before we’ve looked at a plot properly; the free appraisal is the way to find out.
