Building in a large rear garden in Brighton

If you have a long rear garden in Brighton, the first question is usually the obvious one: is there really room for a house down there? The honest answer comes from measuring, not guessing. Separation from existing back windows, garden space for both homes and a drive that works for cars, bins and emergency access all have to fit.

Once we know what could realistically go there, you pick the route that suits you. Some owners prefer a clean sale of the plot, with or without planning. Others want the new home itself, for a parent, a grown-up child or to let. We handle the design and the planning application either way.

What the council will look at in Brighton

Look along your road and the roads behind it. If homes in Brighton or in Hove, Shoreham-by-Sea and Peacehaven already stand behind the original houses, that shows the council the pattern exists locally, although it never makes a new permission certain. Where back gardens are unbroken, a first home behind the street faces closer scrutiny.

How much weight that carries is set out in the council’s Local Plan and in any design guide adopted by Brighton and Hove City Council. We read both before drawing anything, so your scheme answers the questions the planning officer is likely to ask.

This section is worked out for the latitude of Brighton: 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 Brighton

Send us your address in Brighton and a rough idea of what you’d like. We check the planning history around you and the policies Brighton and Hove City 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

  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.
  • A shorter garden changes how your own house feels to live in and may affect what it is worth.
  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.

Brighton: questions to ask

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

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.

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

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 Brighton and Hove City Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Does it cost anything to have my Brighton 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.

How do I find out if my Brighton 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.
