The existing glass roof was found to be leaking and life expired. Our multi disciplinary team were tasked with developing a solution which improved the aesthetic, addressed under and over heating and improved maintenance capabilities. The project brief was extended to include a refurbishment of the entire Atrium area including café and food outlets. The Castle Owen team developed the design to RIBA stage 4 and in addition developed a complex phasing strategy which allowed access to be maintained during the work.
