Building on a corner plot or side garden in Caernarfon

There are two ways to turn a side or corner plot in Caernarfon into a new home. You can sell the land, keeping your house and letting the buyer handle planning and building. Or you can hold on to the land while we design and build the home, which you then keep, let or sell.

Both depend on the same groundwork: a home that respects the street, a safe drive, and enough garden and parking left for your own house. We check that first in a free garden plot appraisal, then help you weigh up the routes against what you want from the land.

What the council will look at in Caernarfon

Take a walk round the junctions near you, in Caernarfon and in Llangefni, Bangor and Bethesda. Side gardens that already have a house on them show the kind of thing the council has accepted before, although each new application stands on its own and is judged under today’s policy. A corner that is still open will draw closer attention.

Those local tests are written into the council’s Local Development Plan (LDP) and any design guidance Gwynedd Council has adopted. Reading both before we draw means the scheme already answers the points an officer is likely to raise.

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.

How we’d take it forward in Caernarfon

You stay in control after the appraisal. Selling means heads of terms in writing, read by your solicitor, before anything is signed. Building means survey and design ahead of a written quote. Whichever you choose, Gwynedd Council receives the application and asks your neighbours for comments, and a decision on a single home often takes a few months, longer if the design needs amending.

  1. Free plot appraisal

    We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.

  2. Choose your route

    Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.

  3. Design and planning

    We draw a home that sits in the street rather than fighting it, usually take pre-application advice, and submit the application. The council consults neighbours and decides; small schemes often take a few months.

  4. Sale or build

    For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.

Worth checking early

  • Losing a side garden or drive changes how your house works day to day, from parking to getting bins round the back.
  • Attaching a home to yours brings party wall, fire and sound separation work, and changes the feel of your own house.
  • A new drive close to a junction may not be acceptable to the highway authority, which can force a different layout.

Caernarfon: questions to ask

Is there a fee for checking my side plot in Caernarfon?

There’s no fee. The appraisal is free and you’re under no obligation. We work from maps, the title and a phone call first, and only visit if the plot seems worth it. Nothing binds you until you’ve picked a route and read the written terms.

Is my Caernarfon side garden wide enough for a new house?

It depends on how wide homes are in your street, the gaps between them, whether the new home would be attached or detached and what the council’s design guidance says. There’s no single minimum width. We measure your plot and the street as part of a free appraisal.

Which body approves a new home on a side plot in Caernarfon?

The planning decision belongs to Gwynedd Council. It checks the proposal against the council’s Local Development Plan (LDP), national policy and its own design guidance, and asks neighbours and the highway authority for their views first. Our role is to prepare and submit a strong application; approval or refusal is the council’s call alone.

Will a new drive near the corner be allowed in Caernarfon?

Only if drivers would have a clear enough view of the road and the junction stays safe. The highway authority comments on this and controls new dropped kerbs. Drives very close to a corner are often resisted, so we check the position on site before designing.
