Building in a large rear garden in Wandsworth

A home at the bottom of a Wandsworth 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 the London Borough of Wandsworth 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.

Wandsworth: light, access and policy

Every application for a new home in a Wandsworth back garden is decided by the London Borough of Wandsworth, which weighs it against the council’s Local Plan, 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.

This section is worked out for the latitude of Wandsworth: around 39° 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.

The next steps, locally

Here’s what happens after you get in touch about a garden in Wandsworth. We look at maps, the title plan and nearby planning history, then call you to talk it through. If the plot looks viable we visit, measure up and check access, levels and trees. You then get a plain summary of what could fit and the routes open to you, with no obligation to take any of them.

  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.
  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • A shorter garden changes how your own house feels to live in and may affect what it is worth.

Wandsworth: questions to ask

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

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 Wandsworth back garden?

The London Borough of Wandsworth decides, using the council’s Local Plan, 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.

Does it cost anything to have my Wandsworth 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.

Will my neighbours in Wandsworth 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.
