What the council will look at in Worthing
Worthing Borough Council will judge a family home against the council’s Local Plan and any guidance it has adopted on garden development and annexes. Some councils spell out how closely an annexe must relate to the main house, such as sharing the drive, garden or parking, and what turns a building into a separate home instead. We read the current policies for your address before design starts, because a scheme drawn to suit the wrong test wastes time and money. Where the position is unclear, the council’s pre-application advice can be worth its fee.
The next steps, locally
From first call to keys, a family home in Worthing follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to Worthing 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.
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.
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
- Planning is the council’s decision, and an annexe is not a way round the rules that apply to a new house.
- A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
- CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.
Worthing: questions to ask
Is CIL payable on a family home in Worthing?
Only if Worthing 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.
How much garden do I need for a family home in Worthing?
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 Worthing 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.
Can I reclaim VAT on a family annexe in Worthing?
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.
Who owns an annexe built in my Worthing 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.
