Llanilid is a highly accessible, large scale reclaimed former open cast mine covering 272ha centrally located in Rhondda Cynon Taf (RCT) within the Cardiff Capital Region (CCR). The opportunity exists to regenerate the site through the delivery of an exemplar mixed-use development that will be among the largest and most ambitious within the CCR.

Site promotion through the LDP


Almost half of the development will be retained as Green Infrastructure including ancient woodlands and watercourses. There will be a focus on active mobility for the local population, helping to contribute to improved health and well-being and a commitment to energy efficiency and decarbonisation.

This unparalleled opportunity for growth will boost housing delivery and employment generation, particularly in the high value creative sector.

The development will include:

  • 95ha for residential use with the capacity to build c.3,500 new homes with an emphasis on well-designed market-rate and affordable homes.
  • New schools plus a wide range of shops, services and community facilities including a well-being centre for health and sports activities, the latter seeing 6ha dedicated to playing pitches.
  • 18ha for employment uses with high levels of digital connectivity built-in and a focus on creative workspaces.
  • Potential for a hotel and restaurant.
  • An emphasis on the commercial leveraging of the creative arts scene that exist in the area – Dragon Studios operate in adjacent premises with Disney and Lucasfilms previously in occupation.

This development aligns strongly with the objective of the Cardiff Capital Region to “bring about significant economic growth in the region through investment, upskilling and improved physical and digital connectivity”. As a result of these endeavours this site is well-placed to attract a number of the sectors that CCR has prioritised including creative, life sciences, compound semiconductors and transport engineering.
