Build a home for family in your garden in Caernarfon

Bringing an elderly parent to live beside you in Caernarfon often feels like the obvious answer, until you look at what the house can offer. A spare room up a flight of stairs rarely suits someone whose mobility is failing. A purpose-built single-storey home in the garden can.

We offer design and build of garden homes for family across Gwynedd, with no steps to climb, a bedroom at ground level and a walk-in shower built in from day one. Planning goes through Gwynedd Council, and we prepare and manage the application for you. Start with a free plot appraisal and we’ll tell you honestly whether your garden looks suitable.

What shapes a plot in Caernarfon

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 Caernarfon is about 37° above the horizon, so a two-storey eaves line around 5 m high casts a shadow of roughly 6.7 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 13°, so we test winter light on both homes, and on next-door gardens, before the layout is fixed.

Noon sun in Caernarfon on 21 March sits about 37° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.7 m. In December the sun is only about 13° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Caernarfon

The next step is a conversation, by phone or through the form, about your garden in Caernarfon 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.

  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. 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.

Worth checking early

  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Questions about garden plots in Caernarfon

Is CIL payable on a family home in Caernarfon?

Only if Gwynedd 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 Caernarfon?

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.

Who owns an annexe built in my Caernarfon 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.

Will an annexe in Caernarfon 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. Gwynedd Council’s council tax team can tell you how the rules apply to your household.
