What the council will look at in Bury St Edmunds
Access usually decides what a Bury St Edmunds garden can take. An annexe can often share your drive because it is used with the house, but a separate home needs an access West Suffolk Council will accept for a dwelling in its own right, with room for cars, bin collection and emergency vehicles. We cover homes in Bury St Edmunds and around Mildenhall, Thetford and Stowmarket, and on every plot we measure the drive width, the view along the road where the access joins it, and how far bins would need to travel, before anyone draws a plan.
How we’d take it forward in Bury St Edmunds
The next step is a conversation, by phone or through the form, about your garden in Bury St Edmunds and who the new home is for. We check access, title, the main planning constraints and any CIL position for your address, then tell you whether an annexe, a separate home or neither looks realistic. If neither does, we’ll say so and explain why.
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
- Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
- VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
- CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.
Your questions, answered for Bury St Edmunds
Can I reclaim VAT on a family annexe in Bury St Edmunds?
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 Bury St Edmunds 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 Bury St Edmunds 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 West Suffolk 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.
Do I need planning permission for a granny annexe in Bury St Edmunds?
Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. West Suffolk 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.
