The sheltered front entrance to the NCT is not intended to be a barrier. Patients can take beepers with them and leave the building for the campus grounds to remain remotely available as needed. A botanical garden and zoo are a short stroll away.

The aluminum-sheathed 'Raum der Stille,' a place of contemplation, quiet, and shelter, is a feature that David Cook sees as 'hanging' within the atrium. 'It is light: It articulates the natural or artificial light falling on its surfaces,' he says. The basket-weave stainless steel cladding comes custom-made from KLASS Metall of Offenburg.

Deep window reveals 'express the thickness of the facades,' Cook explains. 'In combining boards, reveals, shelving, and alternative seating, we tried to create simple elements that lend character.' The view is of the sunken garden.

Workspaces have a direct visible connection to the outside, and a minimum of suspended ceilings create a feeling of space. Lab equipment is shared to encourage researchers to collaborate and to spark informal conversations that nurture new ideas.

In a sunlit lab filled with genotyping equipment, Dr. Christof von Kalle and colleagues at the National Center for Tumor Diseases (NCT) plumb the secrets of cellular mechanisms that create cancers. That is the future. Downstairs on a terrace bordering a sculpted garden, outpatients walk the grueling path that cancer demands right now.

The new $42 million facility near old Heidelberg, Germany, is one of relatively few top-level laboratories to bring fundamental research and frontline patient care under a single roof. This spirit of collaboration is what drives the architectural themes of the 141,000-square-foot building, which opened last October, designed by Behnisch Architekten, the Stuttgart-based shop of partners Stefan Behnisch, David Cook, and Martin Haas.

Built on five floors, including the basement and a sunken garden, the NCT is composed of two main elements: a rectangular plinth wrapped in green reflective glass, and a white stucco 'floating' volume set on top of it, with a punched-hole facade offset at irregular intervals. Operable windows, a terrace, and a balcony connect occupants to the fresh air outside. The central atrium sits at the heart of the building, connecting the disparate elements inside: the lab research floors, the day clinics, and administration.

The atrium is designed to encourage collaboration among different users of the building. Walking inside through the main entrance, one's eye is drawn to a sculpture of the late physician Mildred Scheel in full stride. Scheel founded German Cancer Aid, a nonprofit that funds the NCT, which is a joint project of the University of Heidelberg's Medical School and the Helmholtz Association's German Cancer Research Center. The 5,113-square-foot entrance hall opens around Scheel's likeness, with a freestanding multilevel staircase guiding visitors inside and up.

'What we are doing with this atrium space is making it as complex as possible,' Behnisch architect Peter Schlaier says over coffee in the open caf' on the first level, around a bend and opposite the staircase. 'It feels like a little city. You have streets, places, pathways. From every point the atrium looks different; it's always interesting, you have a lot of different situations.' Patients, researchers, and physicians mingle in the natural eddies created by the angled design of the spaces around the atrium shaft, where they can interact.

Three upper floors connect to this central space. One side of the building houses the research labs, with their higher-than-standard floor-to-floor requirements. On the other side, on the ground and first floors, one finds the day clinics, consulting and examining rooms, lecture and exercise rooms, and the specialist tumor board consulting hall. Administrative offices are mixed throughout, with the bulk on the upper level. A basement level connects the NCT to nearby buildings and a sunken garden level.

These connections integrate the NCT into the small city called Neuenheimer Feld, the university's massive medical and mathematics campus, which is located across the river from Heidelberg's old town. Here, postwar architecture reigns. Passageways connect many of the buildings underneath the greens. The NCT mostly serves clinical outpatients, but it can take gurneys in its big elevators and broad basement halls to bring patients from the advanced heavy-ion therapy lab across the garden or the nearby children's clinic.

The lower levels also mark the foundation of the building's ventilation system. Large loops of 0.31-inch-diameter pipes are embedded inside the floor slabs, coordinated with structural reinforcement, explains Behnisch partner David Cook. The soffits of the in situ slabs are exposed, and the building mass itself serves as a form of thermal storage. Depending on heating or cooling requirements, hot or cold water is pumped through the slabs, allowing the superstructure to function as a radiant device.

Air flows from bottom to top in a hybrid system of natural and artificial ventilation. An intake in a nearby garden draws fresh air underground, where it is either cooled or heated; it circulates through the building up to the folded-construction concrete slab roof, which opens over the atrium to north-facing skylights.

Of great importance is the ability to open windows, Schlaier remarks, adding that this is especially true for chemo patients who perk up when exposed to fresh breezes, as do tired physicians and researchers. The day clinic labs have additional domestic details ' they feature curtains, for instance, and wooden floors. Chemo chairs are designed to lend the impression of a living room, located near views and open windows. Patients can move around freely, spending time on the terrace, balcony, or further afield.

As a whole, the NCT is organized as a think tank for clinical trials. 'It's all about moving promising findings from the laboratory bench to the bedside of the patient,' says NCT spokeswoman Alenka Tschischka. Chance encounters among medical professionals, from spare moments in the caf' to downtime in the lab, may well spark the innovative ideas that eventually become important medical realities for patients.
