Build a home for family in your garden in Colwyn Bay

For grown-up children in Colwyn Bay, the step to a first home can be a long one. If your garden is big enough, a small separate house on part of it could become theirs: with its own planning permission and title, it can be mortgaged in their name and sold when they move on.

That asks more of the plot than an annexe does, including its own garden, parking and an access Conwy County Borough Council will accept. We look at all of that in a free plot appraisal, then design and build the home if the scheme stacks up and you want to go ahead.

What the council will look at in Colwyn Bay

A measured survey is where a family home in Colwyn Bay stops being an idea and becomes a plan. We record boundaries, levels, trees, drains and the windows of your house and the houses next door, then test where the new building can sit. With the spring equinox sun standing near 37° at midday here, a 5 m eaves line throws a noon shadow close to 6.7 m; drawing that onto the survey shows which positions keep light in the main rooms of both homes. Conwy County Borough Council will expect to see the same evidence with the application.

What happens next in Colwyn Bay

Here’s what happens next for a family home in Colwyn Bay. You tell us about your plot and who the home is for, and we carry out a free desktop appraisal of access, space and the planning context. If it looks viable we visit, then set out the annexe and separate-home options. With your go-ahead we survey, design and give you a written quote, then prepare the application for Conwy County Borough Council.

  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. 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.

  3. 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.

  4. 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

  • 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.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Colwyn Bay: questions to ask

How long will building work disrupt my home in Colwyn Bay?

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.

Can I build a separate house in my Colwyn Bay garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Conwy County Borough 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.

Can you design a home in Colwyn Bay for a relative who uses a wheelchair?

Yes. The design can include a level approach and threshold, turning space in each room, a wet room, wider doors and worktops at a usable height. Where Conwy County Borough Council requires a particular access standard through planning, the design meets it; otherwise it’s your choice how far to go. Input from your relative’s occupational therapist is well worth having.

How much garden do I need for a family home in Colwyn Bay?

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 Conwy County Borough 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.
