Building in a large rear garden in Nelson, Gwent

A home at the bottom of a Nelson garden is backland development: building on land behind existing houses that has little or no street frontage of its own. It differs from infill, where a home fills a gap in the street, and it gets a closer look because of privacy and access.

That closer look is why a free appraisal comes first. We check depth, levels, trees, drainage and the title, sketch a realistic layout and explain what Caerphilly County Borough Council is likely to focus on. Then you decide whether to sell the land outright, sell it subject to planning, or have a new home built for you.

Nelson, Gwent: light, access and policy

Overshadowing is often the deciding issue in a long garden. At midday on 21 March the sun in Nelson stands about 38° above the horizon, so a typical two-storey eaves line throws a shadow of roughly 6.3 m. In midwinter the noon sun is only about 15° up and shadows stretch around three times as far.

That’s why the gap between a new home and neighbouring gardens matters, and why a lower roof, or a home set further from the boundary, can make a scheme acceptable. We check the shadows on your actual plot rather than relying on rules of thumb.

How we’d take it forward in Nelson, Gwent

Send us your address in Nelson and a rough idea of what you’d like. We check the planning history around you and the policies Caerphilly County Borough 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. 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.

  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

  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • 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.

Your questions, answered for Nelson, Gwent

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

Caerphilly 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.

How long does planning take for a garden home in Nelson?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.

Will my neighbours in Nelson get a say?

Yes. The council consults neighbours on planning applications, and they can comment or object. Their comments are weighed alongside policy, but objections alone don’t decide the outcome. A layout that respects privacy, light and access usually gives neighbours less to worry about, so we design with them in mind.

Does it cost anything to have my Nelson 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.
