Build a home for family in your garden in Bargoed

For grown-up children in Bargoed, the step to a first home can be a long one. If your garden is big enough, a small separate house on part of it could become theirs: with its own planning permission and title, it can be mortgaged in their name and sold when they move on.

That asks more of the plot than an annexe does, including its own garden, parking and an access Caerphilly County Borough Council will accept. We look at all of that in a free plot appraisal, then design and build the home if the scheme stacks up and you want to go ahead.

Before you decide in Bargoed

A measured survey is where a family home in Bargoed 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. Caerphilly County Borough Council will expect to see the same evidence with the application.

Noon sun in Bargoed 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.

The next steps, locally

Getting started in Bargoed 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. 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. 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.

Questions about garden plots in Bargoed

Can I reclaim VAT on a family annexe in Bargoed?

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.

Is CIL payable on a family home in Bargoed?

Only if Caerphilly County Borough Council has adopted the Community Infrastructure Levy, which its website will confirm, and we check it for you during the appraisal. Where it applies, self-build and residential annexe exemptions exist, but both must be claimed before work starts and can be withdrawn if the home is sold or let within three years of completion.

How long will building work disrupt my home in Bargoed?

A single garden home usually takes several months on site, with the noisiest work, such as groundworks, drainage and heavy deliveries, concentrated near the start. We agree working hours, access and parking with you up front, and with the people next door where it affects them, so your household knows what each week will look like.

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

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Caerphilly County 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.
