Combine back gardens with your neighbours in Harrow

A shared access road is often what makes backland homes possible in Harrow. Instead of several narrow drives, one properly designed road with good visibility at the pavement can serve every new home on the combined land, keep cars further from existing windows and give bin lorries and emergency vehicles the room they need.

The household providing that access gives up the most, so an equalisation agreement usually gives them an extra agreed share. Every owner keeps their house and an agreed garden, and the planning application to the London Borough of Harrow covers the whole site at once rather than plot by plot.

Harrow: light, access and policy

A combined site in Harrow goes to the London Borough of Harrow as one application, judged against the council’s Local Plan and national policy. The council will look at the scheme as a whole: whether one access is safe, whether the layout respects the pattern of the street and gardens around it, and whether every existing home keeps enough privacy, daylight and garden.

That’s a stronger position than several separate applications for single plots, each judged on its own and each with its own drive. It isn’t a guarantee, but it gives the council a scheme it can assess fairly.

What happens next in Harrow

The steps for neighbours in Harrow are: free appraisal, a meeting with the owners, heads of terms, signed agreements, one planning application, then completion and payment of each owner’s share. Setting up a group takes longer than a single plot, and timing depends on the owners, the lenders and the council, so we give ranges rather than promises.

  1. Free appraisal of the combined land

    We look at all the titles together, the possible access points, the surrounding homes and the planning policies that apply, then explain whether a combined scheme looks realistic and roughly what it might allow.

  2. Meet the neighbours

    We meet the owners together or separately, explain how the scheme and the routes work, and answer questions. We don’t approach your neighbours without your agreement, and nobody is committed at this stage.

  3. Collaboration agreement

    Each owner’s own solicitor reviews the documents, and everyone signs a collaboration agreement alongside the sale, option or promotion agreement. Mortgage lenders are asked to consent early, and the agreements are usually protected on each title.

  4. One planning application

    We prepare and submit a single application for the whole site, with one shared access and a layout designed around all the existing homes. The council decides it, and nobody can promise the result.

Worth checking early

  • The owner of the access garden will live beside a shared road, which is why that garden often receives an extra share.
  • If the garden providing the access drops out before signing, the whole scheme may not work.
  • Planning is still the council’s decision; a combined scheme is often stronger, but it can still be refused.

Questions about garden plots in Harrow

Can neighbours in Harrow combine their back gardens for new homes?

Yes, where the gardens adjoin and there’s a workable access. Each owner keeps their house, the land behind is planned as one site, and a collaboration agreement sets out how the value is shared. The London Borough of Harrow decides any planning application on its merits.

Does each Harrow owner keep their own house and garden?

Yes. Each owner keeps their house and an agreed garden for it. Only the land behind is transferred, as a transfer of part at HM Land Registry. New boundaries and fencing for each house are agreed as part of the design.

How many neighbours in Harrow need to take part?

As few as two can be enough. What matters is that the gardens taking part make a workable site and that one of them provides access to the road. We tell you which gardens are essential and which would simply improve the scheme.

Will the London Borough of Harrow prefer a combined scheme to single plots in Harrow?

It often gives the council a better scheme to assess, with one proper access and more space between homes. But every application is judged on its merits against the council’s Local Plan, and the decision is the council’s. We test the layout against its policies before applying.
