What the council will look at in Merton
Before we suggest a combined scheme for homes in CR4, SM4, SW19 and SW20, 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.
How we’d take it forward in Merton
Once the group is interested, we meet the owners, together or one by one, and set out the routes and how equalisation would work. Heads of terms follow. Each owner’s own solicitor reviews the collaboration agreement and the sale, option or promotion documents, and lenders are asked to consent early. Then the single application goes to the London Borough of Merton.
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.
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.
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.
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
- If the garden providing the access drops out before signing, the whole scheme may not work.
- Every owner’s mortgage lender, title and covenants have to be dealt with, and one problem can hold up everyone.
- Several owners have to agree, so a combined scheme usually takes longer to set up than a single plot.
Questions about garden plots in Merton
What if one neighbour in Merton changes their mind?
Before signing, they can simply step back, and we see whether the scheme still works without their garden. After signing, the agreements decide what happens, and they usually bind whoever owns the house next. Your solicitor will check those clauses carefully.
How many neighbours in Merton 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 Merton?
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.
Who gets more if one garden in Merton 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.
