The urban planning concept for the new central building of Hietzing Hospital proposes an elongated, orthogonal structure along Hermesstraße, with the historic perimeter wall deliberately exposed through a ten-metre setback. The building is composed of three pavilions resting on a shared plinth, carefully responding to the surrounding context and functional requirements. Vertical accents within the building plots complement the historic ensemble and integrate sensitively into the existing urban structure.

The plinth serves as a robust foundation, with the building height reducing towards the east to establish a harmonious relationship with its surroundings. The hospital is accessed via a striking main entrance that engages in considered dialogue with the historic architecture. The building concept is organized around a clear separation of public areas, diagnostic facilities, and patient care – with the interstitial "joint" zone forming the operational heart of the hospital, primarily reserved for staff.

The outdoor spaces of the hospital play a central role in patient wellbeing. A car-free, green environment is conceived as a healing garden, actively supporting recovery and regeneration. Historic axes are woven into the design of the approach routes, while the forecourt and inner courtyards create a welcoming and restorative atmosphere. The staff terrace and patient-oriented healing gardens on the upper floors offer spaces for both rest and activity, inviting relaxation and social interaction through generous planting and comfortable seating.

The design also embraces biodiversity through greened rooftops and façades that improve the microclimate and create habitats for plants and wildlife. Taken as a whole, the concept fosters a harmonious, functional, and health-promoting environment for patients, visitors, and clinical staff alike.
