The local picture in Cambridge
Back gardens in CB1, CB2, CB3 and CB4, as anywhere, tend to be divided by fences, hedges and the odd tree, and a combined scheme has to work with all of them. Old boundary hedges may be habitat worth keeping, and mature trees may need an assessment before anything is designed.
We map these features across all the gardens at once, so the layout keeps what matters and the application to Cambridge City Council shows how trees and wildlife have been considered. Doing it across the whole site is simpler and cheaper than doing it garden by garden.
From first call to decision
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 Cambridge City Council.
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.
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.
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.
- The owner of the access garden will live beside a shared road, which is why that garden often receives an extra share.
Your questions, answered for Cambridge
Do we each need a solicitor for a combined scheme in Cambridge?
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.
How many neighbours in Cambridge 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.
Who pays for planning on combined gardens in Cambridge?
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.
Can neighbours in Cambridge 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. Cambridge City Council decides any planning application on its merits.
