Build a home for family in your garden in Wiltshire

Living arrangements sit at the heart of any family build in Wiltshire. Who will move in, how much help they need, whether they will share meals with the main house, and what should happen when circumstances change all shape the design and the planning route.

The councils covering this part of England, among them Swindon Borough Council and Wiltshire Council, judge garden homes on access, privacy, daylight and the space left around both buildings. We prepare the application, manage it with the council and build the home once it is approved. The decision itself always sits with the council.

How councils in Wiltshire look at it

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 Wiltshire, 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 Wiltshire include Swindon Borough Council, Wiltshire Council.

How it works

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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 Wiltshire

Is CIL charged on family homes in Wiltshire?

Some councils charge the Community Infrastructure Levy and some don’t, so it depends where your house is. Where it applies, a self-build exemption and an exemption for residential annexes are available, but they must be claimed before work starts on site, together with a commencement notice. We check the position for your address during the free appraisal.

How long does planning take for an annexe in Wiltshire?

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.

What rules apply to a family home in Wiltshire?

National policy in England sets the framework through the National Planning Policy Framework (NPPF). Each council then applies its own Local Plan policies, along with the council’s design guide or supplementary planning document where relevant. The building must also meet the Building Regulations, and you need to plan for fire engine access (or other measures, often sprinklers, agreed with building control and the fire service where a fire engine can’t get close enough). If the home is for an older relative, it is worth designing to a higher access standard from the start.

Which council decides planning for a garden plot in Wiltshire?

The council for your address decides. The planning authorities covering Wiltshire include Swindon Borough Council and Wiltshire Council. Each judges applications against its own Local Plan and the National Planning Policy Framework (NPPF), together with its design guidance. We prepare and submit the application and deal with the council’s questions, but the decision is always the council’s, never ours.
