Building in a large rear garden in Southampton

A home at the bottom of a Southampton 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 Southampton City 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.

What the council will look at in Southampton

The right layout for a long Southampton garden depends on depth, width and light. With the noon sun only about 16° 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 Southampton City Council’s likely concerns, then show you which are realistic and which aren’t worth pursuing.

This section is worked out for the latitude of Southampton: around 39° of sun at midday in late March and about 16° 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.

What happens next in Southampton

An enquiry about a Southampton garden can start with a short call and a few photos of the garden and the side of the house. A desktop check follows, then a site visit if it’s worth one. If you choose to sell, we agree heads of terms and your solicitor takes it from there. If you choose to build, we move on to a measured survey and design, and a written quote follows.

  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. 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.

  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

  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
  • 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.

Your questions, answered for Southampton

How do I find out if my Southampton 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.

Can I build a house in my back garden in Southampton?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Southampton City Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Will my neighbours in Southampton 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.

Can I sell the end of my garden in Southampton 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.
