The local picture in Wrexham
People living next door are consulted on every planning application, and across LL13 that applies to a family annexe just as much as to a new house. Their privacy, outlook and light carry real weight with Wrexham County Borough Council. A design that keeps upper windows away from adjoining gardens, uses obscure glazing where it has to, and leaves a planted margin along the boundary gives the council fewer reasons to refuse. A quiet word with the people either side before the application goes in is often worthwhile too.
From first call to decision
Here’s what happens next for a family home in Wrexham. 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 Wrexham County Borough Council.
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.
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.
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.
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
- An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
- CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.
- Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
Your questions, answered for Wrexham
Can you design a home in Wrexham 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 Wrexham 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.
Can I build a separate house in my Wrexham garden for my son or daughter?
Possibly, if the plot can work as a home in its own right. Wrexham 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.
Is CIL payable on a family home in Wrexham?
Only if Wrexham County Borough 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.
Who owns an annexe built in my Wrexham 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.
