What the council will look at in Ashford, Surrey
Overlooking decides many garden schemes in Ashford. 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. Spelthorne Borough Council’s own guide decides.
How we’d take it forward in Ashford, Surrey
The steps for neighbours in Ashford 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.
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.
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
- The owner of the access garden will live beside a shared road, which is why that garden often receives an extra share.
- If the garden providing the access drops out before signing, the whole scheme may not work.
- Planning is still the council’s decision; a combined scheme is often stronger, but it can still be refused.
Your questions, answered for Ashford, Surrey
How many neighbours in Ashford 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 Ashford?
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 Ashford 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 Ashford 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.
