Before you decide in Hatfield
Overlooking decides many garden schemes in Hatfield. With the noon sun at about 38° 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. Welwyn Hatfield Borough Council’s own guide decides.
From first call to decision
The steps for neighbours in Hatfield 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.
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
- Every owner’s mortgage lender, title and covenants have to be dealt with, and one problem can hold up everyone.
- The owner of the access garden will live beside a shared road, which is why that garden often receives an extra share.
- Several owners have to agree, so a combined scheme usually takes longer to set up than a single plot.
Hatfield: questions to ask
Will Welwyn Hatfield Borough Council prefer a combined scheme to single plots in Hatfield?
It often gives the council a better scheme to assess, with one proper access and more space between homes. But every application is judged on its merits against the council’s Local Plan, and the decision is the council’s. We test the layout against its policies before applying.
Do we each need a solicitor for a combined scheme in Hatfield?
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 pays for planning on combined gardens in Hatfield?
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 Hatfield 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.
