Building in a large rear garden in Tonbridge

There are two broad ways to use spare land at the back of a house in Tonbridge. The first is to sell it: outright, subject to planning, through an option, or alongside your neighbours. The second is to keep it and have a new home designed, approved and built on it for you.

Which suits you depends on how much risk and involvement you want, and on what the plot can realistically take. A single bungalow, a two-storey home, or a pair sharing one drive across two gardens are all possible on the right site. We look at yours first, free of charge, and explain the trade-offs.

What the council will look at in Tonbridge

The right layout for a long Tonbridge 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 Tonbridge and Malling Borough Council’s likely concerns, then show you which are realistic and which aren’t worth pursuing.

Noon sun in Tonbridge on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.2 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.

The next steps, locally

Here’s what happens after you get in touch about a garden in Tonbridge. 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

  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.

Questions about garden plots in Tonbridge

Will my neighbours in Tonbridge 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 you build a home for my family in my garden in Tonbridge?

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 Tonbridge?

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 Tonbridge and Malling Borough Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Does it cost anything to have my Tonbridge 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.
