Build a home for family in your garden in Westbury

A new home for family in your Westbury garden is built around one person’s needs, which makes the brief unlike other builds. Level paths from the car, a ground-floor bedroom with a shower room beside it, and enough distance from the main house for privacy matter more than an extra bedroom upstairs.

We take that brief through measured survey, design, planning with Wiltshire Council, approval under the Building Regulations and construction, with a written quote once design and survey are done. The first step is free: an appraisal of your plot, access and the planning picture, with a visit if it looks viable.

How it plays out in Westbury

Access usually decides what a Westbury garden can take. An annexe can often share your drive because it is used with the house, but a separate home needs an access Wiltshire Council will accept for a dwelling in its own right, with room for cars, bin collection and emergency vehicles. We cover homes in Westbury and around Warminster, Trowbridge and Frome, and on every plot we measure the drive width, the view along the road where the access joins it, and how far bins would need to travel, before anyone draws a plan.

Noon sun in Westbury on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.2 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.

What happens next in Westbury

Getting started in Westbury costs nothing. Send us a few photos of your garden and the way in, or simply call, and we’ll look at the plot from the desk and talk through your family’s plans. If there’s a realistic scheme, we arrange a site visit. Survey and design are quoted in writing before you commit, and the build price follows once the design is settled.

  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. 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.

  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

  • 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.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Your questions, answered for Westbury

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

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 Wiltshire 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.

Can I build a separate house in my Westbury garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Wiltshire Council will look at access, parking, garden space for both houses, privacy and the character of the street, as it would for any new house. If permission is granted, the plot can be transferred to your child with its own title, with your lender’s consent if the house is mortgaged.

Can I reclaim VAT on a family annexe in Westbury?

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.

Who owns an annexe built in my Westbury 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.
