The Hadyn Ellis Building is the first phase of the exciting and emerging new Science and Innovation Campus at Maindy Road being developed for Cardiff University. It is the home to the institution’s world leading University Research Institutes: the European Cancer Stem Cell and Neuroscience and Mental Health Research Institutes as well as the established Medical Research Centre for Neuropsychiatric Genetics and Genomics. The Hadyn Ellis building is also the new residence for the University Graduate College and provides office and meeting space for Public Health Wales; bringing leaders in science, education and health together within one single building. Acting as a ‘front-door’ to the campus, the Hadyn Ellis building is welcoming, spacious and inclusive. The colourful exterior and landscaping complement its surroundings; while the transparency of the glass façade provides an enticing view into the bustling foyer and exhibition area. The design establishes an interactive and collaborative space where researchers and the wider community can come together, either to enjoy refreshments in the atrium café, discuss an exhibition in the stunning double height exhibition gallery or attend a conference in the comfortable 150 seat lecture theatre. The Hadyn Ellis building is an inspiring place to work and learn. A feature concrete staircase rises through the four storey atrium, giving researchers access to first-class laboratory and office facilities. Open balconies allow visual connection between those visiting and those working within the building and link bridges striding across the atrium provide a physical relationship between dry and wet laboratory spaces. A controlled use of construction materials and colour create identity and act as a natural wayfinding tool, effectively guiding researchers to their destination. Highly sustainable (BREEAM Excellent), the design considers the wellbeing of its users as well as its impact on the environment.
