Daily Work Stop at Hogan for Mice and Fish

Evanston, IL – The O.T. Hogan building is part of the Northwestern University campus. It is one of three buildings dedicated to the study of biological sciences. Its 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. 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 entire sixth floor is comprised of greenhouse pods. Building Blocks has been contracted to replace the exterior window walls of these greenhouse rooms. The unique geometry of Hogan has provided an engaging project. A more unexpected challenge presented itself after windows had been selected and installation planning began.


The biological sciences department house their mice and fish in the Hogan building. These animals have specific breeding habits that are sensitive to the particular vibrations and audio frequencies produced by window replacement. As a result, the installation schedule this summer has been arranged to allow a work stop from 8:30 am to 10:00 am every day. This way, the building improvements will not disrupt the mice and fish or alter the results of studies that are underway.
