Building in a large rear garden in Caernarfon

Not every long garden in Caernarfon should be built on, and we’d rather tell you that early. A deep plot with a narrow side gap, a steep slope or a big protected tree may be better left as garden. Others have enough depth and a usable way in to take a well-placed new home.

Our free appraisal sorts one from the other. If yours works, you can part with the land while staying in your house, agree an option or a conditional sale, or keep it and have us design and build. If it doesn’t, you’ve lost nothing but a conversation.

The local picture in Caernarfon

Every application for a new home in a Caernarfon back garden is decided by Gwynedd Council, which weighs it against the council’s Local Development Plan (LDP), national policy and any local design guidance it has adopted. Those documents often set out separation distances, minimum garden sizes and how homes behind the street should relate to it.

We read the relevant policies for your address before suggesting a layout, and where it helps we ask the council for pre-application advice. That way the scheme you see reflects what is likely to be acceptable locally, not a generic drawing.

This section is worked out for the latitude of Caernarfon: around 37° of sun at midday in late March and about 13° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

What happens next in Caernarfon

Once you’ve had the free appraisal, nothing moves without your say-so. For a sale, terms are agreed in writing before you sign anything. For a build, design and survey come first and the quote follows. In both cases the planning application goes to Gwynedd Council, which consults your neighbours before deciding. Small schemes often take a few months from submission, and surveys or design changes can add more.

  1. Free plot appraisal

    We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.

  2. Choose your route

    You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.

  3. Planning application

    We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.

  4. Sale or build

    If you sell, your solicitor handles the transfer of part and your lender’s release of the plot. If you build, we give a written quote after design and survey, then build and hand over the new home.

Worth checking early

  • Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
  • Surveys and drawings cost money before any decision. On a subject-to-planning sale we normally fund them; on a build you do.
  • A shorter garden changes how your own house feels to live in and may affect what it is worth.

Your questions, answered for Caernarfon

How do I find out if my Caernarfon garden is big enough for a house?

Ask for a free garden plot appraisal. We measure depth and the width of the way in, check what lies behind, look at levels, trees and drainage, and compare your garden with your council’s separation and garden-size guidance. Size alone rarely settles it, because access and neighbours’ privacy matter just as much.

Can you build a home for my family in my garden in Caernarfon?

Yes. If you keep the land, we can design the home, apply for planning permission, build it once permission is granted and arrange the structural warranty lenders usually expect. You receive a written quote after design and survey. If the home is for a relative who will share your kitchen and front door, an annexe may suit better.

Does it cost anything to have my Caernarfon garden looked at?

No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.

How long does planning take for a garden home in Caernarfon?

It varies. Small schemes often take a few months from submission to decision, and longer if surveys, amendments or extra consultation are needed. Pre-application advice and early surveys add time at the start but can save time later. We won’t promise a date, because the council sets the pace.
