Building in a large rear garden in Weymouth

Before paying for drawings of a new home in your Weymouth garden, it helps to know whether the basics stack up. Can a car get in and turn? How far would the new home sit from your back windows and your neighbours’? Would your own house keep a decent garden and somewhere to park?

We answer those questions in a free garden plot appraisal, starting with maps, the title plan and nearby planning history, then a visit if the plot looks viable. You’ll come away knowing whether selling or building makes more sense for you, and what Dorset Council is likely to ask about.

What the council will look at in Weymouth

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

Noon sun in Weymouth 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.

The next steps, locally

Send us your address in Weymouth 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. 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

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

Weymouth: questions to ask

Who decides planning for a home in a Weymouth back garden?

Dorset Council decides, using the council’s Local Plan, national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

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

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 Dorset Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

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

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.

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

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.
