Hogan Building

The O.T. Hogan building at Northwestern University is dedicated to the study of biological sciences. The Brutalist architecture features an unusual four-leaf clover-like footprint. The building was designed in the 1960’s by Walter Netsch during his tenure at Skidmore, Owings & Merrill (SOM). It is an excellent example of his Field Theory; rotating squares to create complex geometries. Limestone panels and aluminum window walls twist around the center.


The sixth floor is composed of greenhouse pods. Building Blocks was contracted to replace the exterior window walls of these greenhouse rooms. The unique geometry of Hogan provided an engaging challenge. Combined with a complete interior renovation, this unusual building has a new lease on life and a 20th-century master’s architectural experimentation is preserved.
