This Grade II listed hospital site presents a complex inter-action of constraints and opportunities. Dating from the late 19th century, the original buildings are part of a densely developed complex of mainly decommissioned buildings that have stood vacant since 1996. A conservation and development plan was prepared, and a steering group formed, which identified a heritage footprint of the most significant listed buildings for retention and others for demolition to make way for the new development. CRI presents a unique challenge to combine and provide modern and appropriate healthcare facilities whilst conserving and restoring one of Cardiff's most significant and historic healthcare sites. The retained buildings are being refurbished and remodelled to provide accommodation equal to that of a new build alternative.
