How it plays out in Wymondham
How the two households will live together shapes the planning case as much as the drawings do. If your parent will eat with you, share the garden and rely on you day to day, an annexe is the natural fit, and that is what South Norfolk Council will expect the application to describe. If your son or daughter will run their own home, pay their own bills and perhaps sell up one day, it is a separate dwelling and will be assessed against the council’s Local Plan as a new house. For a family in NR18, we help set that out clearly from the start.
From first call to decision
From first call to keys, a family home in Wymondham follows a clear order. Free appraisal and site visit; measured survey and design around the person moving in; a planning application to South Norfolk 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
- A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
- 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.
Questions about garden plots in Wymondham
How much garden do I need for a family home in Wymondham?
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 South Norfolk 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 build a separate house in my Wymondham garden for my son or daughter?
Possibly, if the plot can work as a home in its own right. South Norfolk 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 Wymondham 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 South Norfolk 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.
Will an annexe in Wymondham put up my council tax?
It might. Annexes can be banded separately, but exemptions exist for annexes lived in by certain dependent relatives, and in some cases a discount applies where family live there or the annexe is used as part of the main home. Who qualifies depends on the relative’s circumstances and how the annexe is used. South Norfolk Council’s council tax team can tell you how the rules apply to your household.
