Build a home for family in your garden in Swindon

Bringing an elderly parent to live beside you in Swindon often feels like the obvious answer, until you look at what the house can offer. A spare room up a flight of stairs rarely suits someone whose mobility is failing. A purpose-built single-storey home in the garden can.

We offer design and build of garden homes for family across Wiltshire, with no steps to climb, a bedroom at ground level and a walk-in shower built in from day one. Planning goes through Swindon Borough Council, and we prepare and manage the application for you. Start with a free plot appraisal and we’ll tell you honestly whether your garden looks suitable.

How it plays out in Swindon

How the two households will live together shapes the planning case as much as the drawings do. If your parent will eat with you, share the garden and rely on you day to day, an annexe is the natural fit, and that is what Swindon Borough Council will expect the application to describe. If your son or daughter will run their own home, pay their own bills and perhaps sell up one day, it is a separate dwelling and will be assessed against the council’s Local Plan as a new house. For a family in SN1, SN2, SN3 and SN5, we help set that out clearly from the start.

Noon sun in Swindon on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 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.

How we’d take it forward in Swindon

Here’s what happens next for a family home in Swindon. You tell us about your plot and who the home is for, and we carry out a free desktop appraisal of access, space and the planning context. If it looks viable we visit, then set out the annexe and separate-home options. With your go-ahead we survey, design and give you a written quote, then prepare the application for Swindon Borough Council.

  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. 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.

  4. 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.

Worth checking early

  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.

Swindon: questions to ask

How much garden do I need for a family home in Swindon?

There’s no fixed figure. A single-storey annexe close to the house can work on a smaller plot than a separate dwelling, which needs its own garden, parking and access. What matters is whether Swindon Borough Council can be satisfied on privacy, daylight and the space left for both homes. The free appraisal gives you a first view based on your plot’s actual shape and access.

Who owns an annexe built in my Swindon garden?

You do. An annexe stays on the title of your house and usually carries a planning condition tying it to the main home, so it can’t be transferred to the relative living in it. If a family member is paying towards it, record what they’ve put in and what happens on a sale in a written agreement drawn up by a solicitor.

Can I reclaim VAT on a family annexe in Swindon?

Often not. HMRC’s guidance gives an annexe that can’t be used or sold separately from the main house as an example of work that can’t be zero-rated, and the DIY housebuilders refund scheme asks the same question. A separate dwelling is usually treated differently. Take advice from a tax adviser before you settle the planning route, because the wording of the permission matters.

Do I need planning permission for a granny annexe in Swindon?

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Swindon Borough Council will treat it as accommodation linked to your home and will usually add a condition so it can’t be let or sold separately. A garden building used only as a home office or gym is a different matter, but sleeping and cooking take it beyond those allowances.
