Abercarn: light, access and policy
A combined scheme in Abercarn has a wider pool of buyers than a single plot. Once the land has planning, it can be offered to builders and developers working in Abercarn and nearby places such as Risca, Blackwood and Cwmbran, or further afield, who are often more interested in a site for several homes than in one small plot.
If the neighbours choose a sale with planning, the collaboration agreement sets out how a buyer is agreed. If we buy the site, the price is set by the route chosen. Value depends on location, size, access and the permission Caerphilly County Borough Council grants, so we don’t quote figures before an appraisal.
What happens next in Abercarn
Nothing happens without every owner’s agreement. If you’re in Abercarn and think the gardens on your side of the street could work together, call us or use the form. We’ll look at the land first, tell you plainly whether it’s worth pursuing, and only then discuss approaching the other owners, with your say-so and in the way you prefer.
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
- Planning is still the council’s decision; a combined scheme is often stronger, but it can still be refused.
- 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.
Your questions, answered for Abercarn
Does each Abercarn 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.
Will Caerphilly County Borough Council prefer a combined scheme to single plots in Abercarn?
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 Development Plan (LDP), and the decision is the council’s. We test the layout against its policies before applying.
Can neighbours in Abercarn 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. Caerphilly County Borough Council decides any planning application on its merits.
Who gets more if one garden in Abercarn 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.
