In this complex urban setting, the new “urban room” of the dentistry building must have a presence and a sense of responsibility. We believe that this responsibility can be expressed through a symbolic building justified by the clarity of its function, but also a certain “restraint”. If we want to give the campus back its status as a “slice of the city”, the new architecture must be able to resonate with the site. This ambition was part of a very precise interpretation of the site, its components and its potential. Our proposal draws on the urban surroundings to establish a single and clear building which resonates with the existing structure: a tiered building whose main facade looks out onto the public space, and whose south-facing terraces reflect the site’s topographical arrangement. The building carefully respects the location and alignment requirements whilst offering generous outdoor spaces. The tiered system helps establish a functional project with impressive clarity and simplicity.
