Greater London: the planning picture
Most garden plots in Greater London are reached in one of three ways: down a side drive beside the house, from a lane or road at the back, or across someone else’s land. An annexe can often share the existing drive, because it is used with the house. A separate dwelling needs a route in that the council will accept for an independent home, with room for cars to pass, bins to be collected and emergency vehicles to get close enough. If the route is shared with neighbours or crosses land you don’t own, the title needs checking early.

How it works
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.
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.

Questions about family home in your garden in Greater London
Can I build a separate home for my child in Greater London?
Yes, where the plot is big enough to function as an independent home and the council grants permission. It needs its own access, garden, parking and bin store, and must not unduly harm neighbours’ privacy or light. Once approved, the plot can be given its own title, so your child can own it and, if they need to, mortgage it.
How long does planning take for an annexe in Greater London?
Usually a few months from a valid application, though it varies between councils and with how many changes are needed. Applications that draw objections or need extra reports take longer. Pre-application advice adds time at the start but often saves it later by flagging problems before you apply.
Is CIL charged on family homes in Greater London?
Some councils charge the Community Infrastructure Levy and some don’t, so it depends where your house is. Where it applies, a self-build exemption and an exemption for residential annexes are available, but they must be claimed before work starts on site, together with a commencement notice. We check the position for your address during the free appraisal.
How long does planning take for a garden plot in Greater London?
The council usually has eight weeks from validation to decide a small application, though extensions are often agreed, and the whole process takes longer. Surveys, design work, pre-application advice and amendments all add time, and some ecology surveys can only be done at certain times of year. We’ll give you a realistic timetable for your plot rather than a promise.
