Before you decide in Lewisham
Overlooking decides many garden schemes in Lewisham. 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 Lewisham’s own guide decides.
How we’d take it forward in Lewisham
The steps for neighbours in Lewisham 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.
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.
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.
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.
- Every owner’s mortgage lender, title and covenants have to be dealt with, and one problem can hold up everyone.
- Tax depends on each owner’s circumstances, so each should take advice from a tax adviser.
Lewisham: questions to ask
How many neighbours in Lewisham 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.
Can neighbours in Lewisham 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 Lewisham decides any planning application on its merits.
Who pays for planning on combined gardens in Lewisham?
It depends on the route. On a sale subject to planning, we normally fund the application. On planning promotion, nothing is paid upfront and costs are recovered from the proceeds only if a sale with planning happens. On an outright sale, we buy the land as it stands.
What if one neighbour in Lewisham 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.
