Building in a large rear garden in Colwyn Bay

There are two broad ways to use spare land at the back of a house in Colwyn Bay. The first is to sell it: outright, subject to planning, through an option, or alongside your neighbours. The second is to keep it and have a new home designed, approved and built on it for you.

Which suits you depends on how much risk and involvement you want, and on what the plot can realistically take. A single bungalow, a two-storey home, or a pair sharing one drive across two gardens are all possible on the right site. We look at yours first, free of charge, and explain the trade-offs.

How it plays out in Colwyn Bay

Access is where many garden schemes succeed or fail, in Colwyn Bay as anywhere. A drive squeezed past the side of a house has to be wide enough for cars, give drivers a clear view as they pull out, and keep noise and headlights from bothering the people next door. A new or wider dropped kerb also needs the highway authority’s consent.

Homes in LL28 and LL29 with a garage or a wide side passage often start ahead here. Where the gap is tight, a smaller home, a shared drive with a neighbour or access from a lane behind may still work. Because Conwy County Borough Council will look closely at the detail, we design the access before the house.

Noon sun in Colwyn Bay 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 Colwyn Bay

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 Conwy County Borough 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. Measure and test the layout

    We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.

  3. 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.

  4. 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.

Worth checking early

  • 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.
  • A covenant, a mortgage, a public sewer or a protected tree can slow a scheme down or stop it altogether.

Colwyn Bay: questions to ask

Who decides planning for a home in a Colwyn Bay back garden?

Conwy County Borough Council decides, using the council’s Local Development Plan (LDP), national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.

Can I build a house in my back garden in Colwyn Bay?

Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Conwy County Borough Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.

Can you build a home for my family in my garden in Colwyn Bay?

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.

How long does planning take for a garden home in Colwyn Bay?

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.
