What shapes a plot in Llantwit Major
Overlooking decides many garden schemes in Llantwit Major. 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. Vale of Glamorgan Council’s own guide decides.
From first call to decision
To start, send us the addresses of the gardens involved in Llantwit Major, or just your own if the neighbours haven’t been asked yet. We run a free desk-based check of the titles, access options and planning position, then explain in writing whether a combined scheme looks realistic before anyone talks to the neighbours in detail.
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.
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.
Worth checking early
- Tax depends on each owner’s circumstances, so each should take advice from a tax adviser.
- Planning is still the council’s decision; a combined scheme is often stronger, but it can still be refused.
- If the garden providing the access drops out before signing, the whole scheme may not work.
Your questions, answered for Llantwit Major
Does each Llantwit Major 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 pays for planning on combined gardens in Llantwit Major?
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.
Who gets more if one garden in Llantwit Major 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.
Will Vale of Glamorgan Council prefer a combined scheme to single plots in Llantwit Major?
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.
