Backland development in Mountain Ash

If your house in Mountain Ash has a long back garden, a wide side plot or a row of garages behind it, there may be space for a new home. Backland Development gives you two ways to use that land. You can sell or partner on the plot and carry on living in your house, or you can keep it and have us design, get planning for and build a new home there.

Every enquiry from Mountain Ash and nearby places such as Treharris, Rhondda and Aberdare starts the same way: a free garden plot appraisal with no obligation. We look at the plot from a desk, talk it through with you and arrange a visit if it looks viable. Planning decisions rest with Rhondda Cynon Taf County Borough Council, so we never promise an outcome.

The kinds of plot we look at in Mountain Ash

Not every plot we consider is a garden. Garage courts, lock-up blocks, old workshops and yards behind houses in Mountain Ash can sometimes take a new home, particularly where a vehicle access already exists. These sites raise their own questions, such as who owns the access, whether anyone else has rights over it and what the ground was used for before. Alongside them, we consider long back gardens, wide side gardens, corner plots and bungalows on large plots, each judged on its own access, space and planning position.

Planning and light in Mountain Ash

Planning applications for new homes in gardens in Mountain Ash are decided by Rhondda Cynon Taf County Borough Council. Its decisions follow the council’s Local Development Plan (LDP) and Planning Policy Wales (PPW). Officers usually focus on access, privacy, daylight, the character of the street and the garden left for both homes. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but Rhondda Cynon Taf County Borough Council’s own guidance decides. We prepare the application with care; the decision is always the council’s.

Questions about garden plots in Mountain Ash

How much is my garden plot in Mountain Ash worth?

There’s no honest figure without looking at the plot. Value depends on location, size, access, title and planning, and costs such as a long drive or difficult ground come straight off what the land is worth. Our free appraisal looks at all of that before we talk about price.

How long does a garden plot deal in Mountain Ash usually take?

It depends on the route. A sale of a plot that already has planning moves at the pace of the solicitors and your lender. Routes that need planning usually take many months, because of surveys, design, the council’s decision period and any amendments. Design and build usually takes well over a year in total.

How do you stop a new home in Mountain Ash overshadowing the neighbours?

By testing the layout against the sun and the council’s guidance. At midday on 21 March the sun in Mountain Ash is about 38° up, so a 5 m eaves line casts a shadow of roughly 6.3 m; in December it is far lower. Spacing, roof height, orientation and single-storey designs all help keep light where it belongs.

Can you build a house in my back garden in Mountain Ash that I keep?

Yes. Our design and build route covers the survey, design, planning application, Building Regulations, construction and handover, while the land and the new home stay yours. You can sell it, let it or use it for family. You’ll get a written quote once the design and survey are done, and any earlier price range is a guide only.
