Tsoi Kobus Design

Tsoi Kobus Design is a Boston-area architecture and planning firm founded in 1983, with a national practice concentrated in healthcare, science, and academic buildings. The firm serves as design partner on Henry Ford Health’s $2.2 billion Destination: Grand hospital in Detroit, a 20-story patient tower developed with architect of record HDR. Tsoi Kobus focuses on complex institutional environments where clinical workflow and research adjacencies shape the plan. Its work spans hospitals, medical research buildings, and university facilities for health systems and academic clients across the United States.

An architecture practice built around research environments

Tsoi Kobus Design is a Boston-area architecture and planning firm founded in 1983, with a practice that has grown to somewhere between 51 and 200 staff over four decades. Its core disciplines are architecture, interior design, and planning, applied largely to buildings where technical complexity, rather than style alone, drives the design. That orientation has shaped the firm into a specialist in some of the more demanding corners of the built environment.

The focus shows plainly in the building types the practice concentrates on. Science and technology facilities call for laboratory environments with exacting requirements for air, vibration, and services. Healthcare facilities carry their own dense web of clinical, regulatory, and patient-experience demands. Higher education buildings sit between the two, often housing teaching and research under one roof. The work extends to highly specialised commissions such as proton therapy centers, which combine advanced medicine with heavy engineering and shielding, and to commercial development. Proton therapy centers in particular capture the kind of research-driven, technically intense environment the firm is set up to handle.

Design in these sectors rewards deep, repeated experience far more than breadth, and concentrating on research and clinical environments has let the firm build exactly that. Tsoi Kobus Design now operates as part of DLR Group rather than as a standalone practice, folding its healthcare and science expertise into a larger national organisation while continuing to carry its own name on the work it produces.

For an institution planning a laboratory, a hospital wing, or a teaching-and-research building, that kind of specialised track record is worth more than general design experience, because the technical requirements leave little room for a learning curve. Now operating within DLR Group, the practice pairs its long focus on research and clinical environments with the reach and resources of a larger national firm.
