New business park in the Valleys to launch in November

Parc Eirin in Tonyrefail will provide around 50,000 sq ft of new industrial space

A new business park in the Valleys will be launched in November following a £8.2m investment by family-owned commercial property developer Ty Rhosyn Developments.

Parc Eirin, in Tonyrefail, will provide around 50,000 sq ft of flexible business and industrial space across 34, self-contained terraced units, each ranging from 1,292 sq. ft. to 1,550 sq. ft. The development is being marketed by property advisory firm Knight Frank.

Built over two phases the park will be capable of accommodating up to 150 jobs in Rhondda Cynon Taf. Llantrisant-based Ty Rhosyn purchased the plot of land in March from the Welsh Government.

The first 17 units will be ready for occupation in November, with the second set expected to be delivered during the second half of 2027.

Rosie Christopher, commercial director at Ty Rhosyn Developments, said: “Parc Eirin brings a new offering to Rhondda Cynon Taf. The area has plenty of large industrial units, but few options designed for smaller, flexible uses – and that type of space is in high demand.

“We are a family-run operation, and our team is from the area too. That has shaped our approach to Parc Eirin from the outset, creating a business park that supports local employers and opportunities for the wider community.”

Rhys Price, associate at Knight Frank Cardiff, said: “Parc Eirin is arriving at exactly the right moment. There has been a chronic shortage of small, high‑quality industrial and business units across Rhondda Cynon Taf, and demand continues to outstrip supply. When comparable space has come forward in the past, it has been taken up very quickly.

“The development directly addresses that gap by delivering modern, flexible units for growing businesses. It’s a development that will make a meaningful difference to local employers and the wider economy.”
