Combine back gardens with your neighbours in Llantrisant

If your back garden in Llantrisant is long but has no way in from the road, your neighbours may hold the answer. Combining the far ends of adjoining gardens creates one site with one shared access, which can turn several unusable strips into a scheme Rhondda Cynon Taf County Borough Council can properly consider.

Each owner keeps their house and a garden for it. A collaboration agreement sets out how the proceeds are shared, including an agreed extra for the garden that gives the access, and every owner has their own solicitor. Our appraisal of the combined land is free.

Before you decide in Llantrisant

Overlooking decides many garden schemes in Llantrisant. 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. Rhondda Cynon Taf County Borough Council’s own guide decides.

Noon sun in Llantrisant on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

What happens next in Llantrisant

Nothing happens without every owner’s agreement. If you’re in Llantrisant 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.

  1. 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.

  2. 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.

  3. 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.

  4. 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

  • 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.

Your questions, answered for Llantrisant

Who gets more if one garden in Llantrisant 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 Rhondda Cynon Taf County Borough Council prefer a combined scheme to single plots in Llantrisant?

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.

How many neighbours in Llantrisant 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.

Does each Llantrisant 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.
