Desborough: light, access and policy
A measured survey is where a family home in Desborough 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 38° at midday here, a 5 m eaves line throws a noon shadow close to 6.5 m; drawing that onto the survey shows which positions keep light in the main rooms of both homes. North Northamptonshire Council will expect to see the same evidence with the application.
How we’d take it forward in Desborough
The next step is a conversation, by phone or through the form, about your garden in Desborough 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.
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
- CIL exemptions are lost if work starts before the claim is made, and can be withdrawn if the home is sold or let within three years.
- An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
- VAT savings available on a separate dwelling often don’t apply to an annexe; take advice from a tax adviser before choosing.
Questions about garden plots in Desborough
Can I build a separate house in my Desborough garden for my son or daughter?
Possibly, if the plot can work as a home in its own right. North Northamptonshire 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 Desborough 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 North Northamptonshire 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 Desborough 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. North Northamptonshire Council’s council tax team can tell you how the rules apply to your household.
Do I need planning permission for a granny annexe in Desborough?
Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. North Northamptonshire 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.
