Building in a large rear garden in Dorchester

If you have a long rear garden in Dorchester, 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.

The local picture in Dorchester

Wherever your home sits within DT1, the street around it shapes what’s possible. Some roads already have houses built behind the originals, while elsewhere the gardens stay unbroken from end to end. Councils read that pattern when judging a new home, so we look at your surroundings as well as your plot.

The same applies if you live just outside Dorchester, in nearby places such as Weymouth, Portland and Poole. The first step doesn’t change: a free look at depth, access, levels and what a new home would mean for the people next door.

Noon sun in Dorchester on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.1 m. In December the sun is only about 16° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Dorchester

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

  • 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.

Your questions, answered for Dorchester

Will my neighbours in Dorchester 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.

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

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.

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

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.

Does it cost anything to have my Dorchester 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.
