I've worked with BCJ Architects on a few of their projects and always admired their use of materials that are layered such that they seem to float across the facades of their buildings.
In the next round of studies, the design moved back from the main corridor to an inner site location. Designing for century-old hospitals can be an interesting challenge, as they've typically had several additions over many years, resulting in a lack of cohesive architectural identity and difficult way-finding for visitors. The above concept looks at wrapping older sections to tie the complex together.
