How it plays out in Prescot
A measured survey is where a family home in Prescot 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. Knowsley Metropolitan Borough Council will expect to see the same evidence with the application.
The next steps, locally
From first call to keys, a family home in Prescot follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to Knowsley Metropolitan Borough Council; approval under the Building Regulations and any CIL exemption claimed before work starts; then the build, with you living next door throughout. You receive a written quote after design and survey, and we keep the household updated at each stage.
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.
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.
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 is in place and any CIL exemption has been claimed.
Worth checking early
- Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
- An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
- A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
Prescot: questions to ask
Who owns an annexe built in my Prescot 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.
Can you design a home in Prescot 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 Knowsley Metropolitan 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 reclaim VAT on a family annexe in Prescot?
Often not. HMRC’s guidance gives an annexe that can’t be used or sold separately from the main house as an example of work that can’t be zero-rated, and the DIY housebuilders refund scheme asks the same question. A separate dwelling is usually treated differently. Take advice from a tax adviser before you settle the planning route, because the wording of the permission matters.
Do I need planning permission for a granny annexe in Prescot?
Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Knowsley Metropolitan Borough Council will treat it as accommodation linked to your home and will usually add a condition so it can’t be let or sold separately. A garden building used only as a home office or gym is a different matter, but sleeping and cooking take it beyond those allowances.
