How councils in West Glamorgan look at it
Under Planning Policy Wales (PPW), 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 Development Plan (LDP) usually adds local detail. For a family home in West Glamorgan, 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 West Glamorgan include City and County of Swansea, Neath Port Talbot County Borough Council.
How it works
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.
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.
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.
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.
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 West Glamorgan
Do you build family homes across all of West Glamorgan?
Yes, we cover garden plots throughout West Glamorgan, including in and around Swansea, Neath, Port Talbot and Gorseinon. Every enquiry starts with a free desktop appraisal of the plot and the planning context, and we arrange a site visit if the scheme looks viable. Design, planning and build follow only if you decide to go ahead.
Can I build a separate home for my child in West Glamorgan?
Yes, where the plot is big enough to function as an independent home and the council grants permission. It needs its own access, garden, parking and bin store, and must not unduly harm neighbours’ privacy or light. Once approved, the plot can be given its own title, so your child can own it and, if they need to, mortgage it.
How long does planning take for an annexe in West Glamorgan?
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.
Can neighbours in West Glamorgan combine their gardens?
Yes. Putting two or more adjoining back gardens together can allow one shared access and a better layout than separate plots. Each owner keeps their house. The owners usually sign a collaboration agreement, with an equalisation clause so that value is shared fairly even though only one garden provides the access. Each household should take its own legal advice.
