The local picture in Burry Port
Daylight matters twice over when the new home is for a relative who spends much of the day indoors. At noon on 21 March the sun in Burry Port is about 38° above the horizon, so a two-storey eaves line around 5 m high casts a shadow of roughly 6.3 m. A single-storey annexe with eaves at half that height casts one about half as long, which is one reason low buildings often sit more easily in a garden. By late December the midday sun climbs only about 15°, so we test winter light on both homes, and on next-door gardens, before the layout is fixed.
How we’d take it forward in Burry Port
The next step is a conversation, by phone or through the form, about your garden in Burry Port and who the new home is for. We check access, title, the main planning constraints and any CIL position for your address, then tell you whether an annexe, a separate home or neither looks realistic. If neither does, we’ll say so and explain why.
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.
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.
- Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
- An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
Your questions, answered for Burry Port
Who owns an annexe built in my Burry Port 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.
Is CIL payable on a family home in Burry Port?
Only if Carmarthenshire County 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.
Can I build a separate house in my Burry Port garden for my son or daughter?
Possibly, if the plot can work as a home in its own right. Carmarthenshire County 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.
How much garden do I need for a family home in Burry Port?
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 Carmarthenshire County 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.
