The local picture in Mountain Ash
Shadow and distance are often why a combined site in Mountain Ash works better than a single garden. With the sun at about 38° at noon in late March, the shadow from a 5 m eaves line reaches roughly 6.3 m, so a home squeezed into one narrow garden can end up too close to the houses it backs onto.
Joining gardens with neighbours lets new homes sit towards the middle of a wider site, away from existing windows, with one shared access. Promotion suits that kind of scheme, because planning costs are spread across more land and the site is sold as one well-planned whole. Rhondda Cynon Taf County Borough Council still makes the decision.
What happens next in Mountain Ash
The first step for a Mountain Ash garden is a conversation and a desktop check, at no cost. We then send written heads of terms covering the term, minimum price, cost cap and fee. Once the agreement is signed, we commission surveys and drawings, take pre-application advice from Rhondda Cynon Taf County Borough Council where it helps, and submit the application. Marketing starts only after permission is granted.
Free plot appraisal
We check your title plan, access, the surrounding gardens and the policies in the council’s Local Development Plan (LDP) as a desktop exercise, then talk it through with you. If it looks viable, we visit. No cost and no obligation.
We apply for planning
We commission the surveys and drawings, take pre-application advice where it helps, submit the application and deal with the council’s questions. You pay nothing at this stage, and the decision is the council’s.
Marketing and sale
With permission granted, the plot is marketed as the agreement sets out. You see the offers and approve the buyer, and the plot can’t be sold below the minimum price without your written consent.
Completion and payout
On completion, sale costs, our capped planning costs and our fee come out of the proceeds in the order the agreement sets. The balance is paid to you through your solicitor.
Worth checking early
- You can’t sell the plot to anyone else while the agreement runs, so the term length matters.
- The plot’s price isn’t known until it’s marketed with permission; it depends on location, size, access and the permission itself.
- Promotion takes longer than a straight sale: planning, then marketing, then completion, and each stage can run on.
Mountain Ash: questions to ask
Can neighbours in Mountain Ash combine gardens for a planning promotion?
Yes, and promotion often works better that way. Adjoining gardens can share one access and allow a better layout. Each owner keeps their house, signs an agreement setting out how proceeds are shared, and takes advice from their own solicitor. We can appraise the combined land as one site first.
Who decides a planning application for a garden plot in Mountain Ash?
Rhondda Cynon Taf County Borough Council decides it, using the council’s Local Development Plan (LDP) and national policy in PPW. Nobody can promise the outcome. Under promotion we prepare and submit the application at our cost and deal with the council’s questions, but the decision is the council’s, and it can grant, refuse or ask for changes.
Do I pay anything upfront for planning promotion in Mountain Ash?
No. We fund the surveys, drawings and planning fees. Those costs are recovered from the sale proceeds, within a cap set in the heads of terms, only if a sale with planning happens. Your reasonable legal fees for the agreement are also covered up to an agreed cap.
How long does planning promotion take for a garden in Mountain Ash?
It usually takes longer than a straight sale. Design and surveys often take a few months, then Rhondda Cynon Taf County Borough Council needs time to decide, and marketing and conveyancing follow. The council’s workload, extra reports and any appeal drive the timing, so we give a realistic range after the appraisal.
