Building in a large rear garden in Lewisham

A home at the bottom of a Lewisham 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 Lewisham 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.

Lewisham: light, access and policy

The right layout for a long Lewisham garden depends on depth, width and light. With the noon sun only about 15° up in December, a two-storey home placed close to a neighbour’s boundary can darken their garden for much of the winter. A single-storey home, or rooms in the roof with carefully placed roof lights, often sits more comfortably.

Wider plots sometimes take two homes, and two long gardens side by side can share a single drive. We test each option against the London Borough of Lewisham’s likely concerns, then show you which are realistic and which aren’t worth pursuing.

Noon sun in Lewisham on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

From first call to decision

Once you’ve had the free appraisal, nothing moves without your say-so. For a sale, terms are agreed in writing before you sign anything. For a build, design and survey come first and the quote follows. In both cases the planning application goes to the London Borough of Lewisham, which consults your neighbours before deciding. Small schemes often take a few months from submission, and surveys or design changes can add more.

  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.

Worth checking early

  • Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.

Your questions, answered for Lewisham

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

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.

How do I find out if my Lewisham 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.

Does it cost anything to have my Lewisham 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 I sell the end of my garden in Lewisham and keep my house?

Yes. The plot is sold as a transfer of part and gets its own title at HM Land Registry. If your house is mortgaged, your lender must agree to release the plot. We can buy suitable plots with or without planning, always subject to survey, title and contract.
