Before you decide in Sutton
Overlooking decides many garden schemes in Sutton. With the noon sun at about 39° in late March, when a 5 m eaves line casts shade around 6.3 m deep, and with back windows facing in several directions, space matters.
On a combined site there’s room to turn the new homes, use single-storey elements near boundaries, and keep upstairs windows away from neighbours. Many councils use separation guides of around 21 metres between facing back windows, and around 12 to 15 metres from a back window to a blank side wall. The London Borough of Sutton’s own guide decides.
The next steps, locally
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 Sutton.
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.
Agree how value is shared
Heads of terms set out the route, each owner’s share, any extra for the garden providing the access, what happens if someone drops out, and the cap on each owner’s reasonable legal fees where it applies.
Completion and shares paid
When the site is sold with planning, or bought by us as agreed, each owner transfers their part, and the proceeds are divided through the solicitors exactly as the collaboration agreement sets out.
Worth checking early
- Several owners have to agree, so a combined scheme usually takes longer to set up than a single plot.
- If the garden providing the access drops out before signing, the whole scheme may not work.
- Tax depends on each owner’s circumstances, so each should take advice from a tax adviser.
Sutton: questions to ask
Does each Sutton 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 Sutton 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.
Can neighbours in Sutton 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 Sutton decides any planning application on its merits.
What if one neighbour in Sutton 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.
