Build a home for family in your garden in Gorseinon

A new home for family in your Gorseinon 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 the City and County of Swansea, 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.

The local picture in Gorseinon

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 the City and County of Swansea 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 Development Plan (LDP) as a new house. For a family in SA4, we help set that out clearly from the start.

Noon sun in Gorseinon 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.

From first call to decision

From first call to keys, a family home in Gorseinon follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to the City and County of Swansea; approval under the Building Regulations as they apply in Wales and any CIL exemption claimed before work starts; then the build, with you living next door throughout. You receive a written quote after design and survey, and we keep the household updated at each stage.

  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

  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.

Gorseinon: questions to ask

Can you design a home in Gorseinon for a relative who uses a wheelchair?

Yes. The design can include a level approach and threshold, turning space in each room, a wet room, wider doors and worktops at a usable height. Where the City and County of Swansea requires a particular access standard through planning, the design meets it; otherwise it’s your choice how far to go. Input from your relative’s occupational therapist is well worth having.

Is CIL payable on a family home in Gorseinon?

Only if the City and County of Swansea 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.

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

Possibly, if the plot can work as a home in its own right. The City and County of Swansea 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.

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

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 the City and County of Swansea 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.
