Combine back gardens with your neighbours in Cardiff

Neighbours in Cardiff sometimes find that one garden alone is too narrow, too short or too hard to reach, while the land behind several houses together would make a sensible site for new homes. That’s land assembly on a small scale.

We can look at the gardens as one site, show the group what a combined layout might allow, and explain how value is shared fairly through equalisation. Nobody has to commit until they’ve taken their own advice. If a single garden works perfectly well on its own, with its own route to the road, we’ll tell you that too.

The local picture in Cardiff

Before we suggest a combined scheme for homes in CF5, CF10, CF11 and CF14, we read what the council’s Local Development Plan (LDP) says about garden land, design and parking, and we look at past decisions on similar sites nearby. Those tell us how the council has treated backland schemes before.

If policy points against building behind the houses, combining gardens won’t change that, and we’ll say so. If it supports well-designed schemes with proper access, a combined site is often the best way to meet that standard.

This section is worked out for the latitude of Cardiff: around 39° of sun at midday in late March and about 15° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

From first call to decision

To start, send us the addresses of the gardens involved in Cardiff, 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.

  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. 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.

  4. 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

  • Planning is still the council’s decision; a combined scheme is often stronger, but it can still be refused.
  • Several owners have to agree, so a combined scheme usually takes longer to set up than a single plot.
  • Every owner’s mortgage lender, title and covenants have to be dealt with, and one problem can hold up everyone.

Cardiff: questions to ask

What if one neighbour in Cardiff 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.

Who pays for planning on combined gardens in Cardiff?

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.

Do we each need a solicitor for a combined scheme in Cardiff?

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 Cardiff 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.
