What to know in Dorset
Under the National Planning Policy Framework (NPPF), councils weigh the character of an area and the effect on neighbours when deciding whether a home can go in a garden, and the council’s Local Plan usually adds local detail. For a family home in Dorset, that means the design has to suit its surroundings as well as the relative moving in. Single-storey buildings, careful window placement and boundary planting often help. Many councils use separation distances of around 21 metres between facing back windows, but your council’s own guide decides.
Planning authorities covering Dorset include BCP Council, Dorset Council.
How it works
Free plot appraisal
We look at your plot, access and the planning picture from the desk, talk through who will live in the new home, and visit if it looks viable. There’s no cost and no obligation.
Annexe or separate home
We set out both routes for your plot, covering what each means for planning, ownership, council tax, CIL and VAT, so you can decide with your family and advisers before design starts.
Survey and design
A measured survey, then a design built around the person moving in: step-free routes, a ground-floor bedroom if needed and privacy for both households. You get a written quote after design and survey.
Planning and approvals
We prepare and submit the planning application and manage it with the council, which makes the decision. Before work starts, approval under the Building Regulations is in place and any CIL exemption has been claimed.
Build and handover
We build while you carry on living next door, with access, deliveries and working hours agreed up front. At handover you get the completion certificate and the paperwork you’ll need for council tax, lenders and any VAT claim.

Questions about family home in your garden in Dorset
Do councils in Dorset allow annexes for elderly parents?
They can, where the annexe is clearly linked to the main house and the plot can take it without harming neighbours or the character of the area. Each council decides its own applications against its local policies, so what is acceptable on one street may not be on another. Councils covering Dorset include BCP Council and Dorset Council.
Do you build family homes across all of Dorset?
Yes, we cover garden plots throughout Dorset, including in and around Bournemouth, Poole, Weymouth and Christchurch. Every enquiry starts with a free desktop appraisal of the plot and the planning context, and we arrange a site visit if the scheme looks viable. Design, planning and build follow only if you decide to go ahead.
How long does planning take for an annexe in Dorset?
Usually a few months from a valid application, though it varies between councils and with how many changes are needed. Applications that draw objections or need extra reports take longer. Pre-application advice adds time at the start but often saves it later by flagging problems before you apply.
Do you buy garden plots in Dorset?
Yes. We buy suitable garden plots across Dorset directly, with or without planning permission, always subject to survey, title and contract. We also offer sales subject to planning, options, planning promotion and joint ventures. Which route fits depends on your plot, so the starting point is a free, no-obligation appraisal.
