Combine back gardens with your neighbours in Hillingdon

If your back garden in Hillingdon is long but has no way in from the road, your neighbours may hold the answer. Combining the far ends of adjoining gardens creates one site with one shared access, which can turn several unusable strips into a scheme the London Borough of Hillingdon can properly consider.

Each owner keeps their house and a garden for it. A collaboration agreement sets out how the proceeds are shared, including an agreed extra for the garden that gives the access, and every owner has their own solicitor. Our appraisal of the combined land is free.

Before you decide in Hillingdon

Before we suggest a combined scheme for homes in HA4, UB3, UB4 and UB8, we read what the council’s Local Plan says about garden land, design and parking, and we look at past decisions on similar sites nearby. Those tell us how the council has treated backland schemes before.

If policy points against building behind the houses, combining gardens won’t change that, and we’ll say so. If it supports well-designed schemes with proper access, a combined site is often the best way to meet that standard.

What happens next in Hillingdon

The steps for neighbours in Hillingdon 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

  • Tax depends on each owner’s circumstances, so each should take advice from a tax adviser.
  • If the garden providing the access drops out before signing, the whole scheme may not work.
  • Several owners have to agree, so a combined scheme usually takes longer to set up than a single plot.

Your questions, answered for Hillingdon

How many neighbours in Hillingdon 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.

Do we each need a solicitor for a combined scheme in Hillingdon?

Yes. Each owner has different interests, a different title and possibly a mortgage, so each needs independent advice. On option and promotion agreements we cover each owner’s reasonable legal fees up to the cap agreed in the heads of terms.

Does each Hillingdon 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.

Who gets more if one garden in Hillingdon provides the access?

Usually the owner of the access garden receives an extra agreed share, because their land makes the scheme possible and their house is most affected by passing cars. The exact method is agreed by everyone in the collaboration agreement before planning starts.
