Site promotion through the LDP

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.

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:

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.
