Build a home for family in your garden in Cwmbran

A new home for family in your Cwmbran 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 Torfaen County Borough Council, approval under the Building Regulations as they apply in Wales 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.

What the council will look at in Cwmbran

A measured survey is where a family home in Cwmbran stops being an idea and becomes a plan. We record boundaries, levels, trees, drains and the windows of your house and the houses next door, then test where the new building can sit. With the spring equinox sun standing near 38° at midday here, a 5 m eaves line throws a noon shadow close to 6.3 m; drawing that onto the survey shows which positions keep light in the main rooms of both homes. Torfaen County Borough Council will expect to see the same evidence with the application.

This section is worked out for the latitude of Cwmbran: around 38° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

The next steps, locally

Getting started in Cwmbran 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. 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 as they apply in Wales 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

  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • 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.

Cwmbran: questions to ask

Who owns an annexe built in my Cwmbran 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 build a separate house in my Cwmbran garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Torfaen County Borough 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.

Will an annexe in Cwmbran put up my council tax?

It might. Annexes can be banded separately, but exemptions exist for annexes lived in by certain dependent relatives, and in some cases a discount applies where family live there or the annexe is used as part of the main home. Who qualifies depends on the relative’s circumstances and how the annexe is used. Torfaen County Borough Council’s council tax team can tell you how the rules apply to your household.

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

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 Torfaen County 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.
