A new business park in Tonyrefail is set to launch in November, after an £8.2 million investment from family-owned commercial property developer Ty Rhosyn Developments.
Parc Eirin will provide around 50,000 sq. ft. of flexible business and industrial space across 34 high-quality, self-contained terraced units, each ranging from 1,292 sq. ft. to 1,550 sq. ft. The development is being marketed by independent commercial property consultants Knight Frank.
Built over two phases, Parc Eirin will be capable of accommodating up to 150 jobs in Rhondda Cynon Taf. Llantrisant-based Ty Rhosyn purchased the plot of land in March 2026 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.
Each of Parc Eirin’s units has been built to a high specification, targeting an Energy Performance Certificate (EPC) rating of C. The wider development also features electric vehicle charging points, plentiful greenery on site, and access to nearby rain gardens.
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.
“With high‑street rents rising, business owners are looking for alternative accommodation. Parc Eirin gives them the opportunity to turn their idea into reality or take the next step on their growth journey – whether they are running a small business, setting up an office, or looking for secure storage for trade work.
“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, added: “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.”
