Build a home for family in your garden in Hackney

If you have a long or wide garden in Hackney, there may be room for a home where a parent or grown-up child can live close by with their own front door. That might mean an annexe used with your house, or a home that stands alone with permission and paperwork of its own.

The London Borough of Hackney decides either way, so the first step is to find out what your plot can realistically carry. Our free plot appraisal covers access, space, privacy and the main planning constraints, and talks through who the home is for, before you spend any money on drawings.

Hackney: light, access and policy

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 the London Borough of Hackney 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 E2, E5, E8 and E9, we help set that out clearly from the start.

This section is worked out for the latitude of Hackney: around 38° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

What happens next in Hackney

Getting started in Hackney costs nothing. Send us a few photos of your garden and the way in, or simply call, and we’ll look at the plot from the desk and talk through your family’s plans. If there’s a realistic scheme, we arrange a site visit. Survey and design are quoted in writing before you commit, and the build price follows once the design is settled.

  1. 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.

  2. 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.

  3. 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.

  4. 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.
  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.
  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.

Hackney: questions to ask

How much garden do I need for a family home in Hackney?

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 the London Borough of Hackney 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.

Do I need planning permission for a granny annexe in Hackney?

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. The London Borough of Hackney 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.

Can I build a separate house in my Hackney garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. The London Borough of Hackney 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 I reclaim VAT on a family annexe in Hackney?

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.
