The New York office of architecture firm Perkins+Will transformed a vacant 1980s suburban office building into Memorial Sloan Kettering Monmouth, a new cancer center located in Middletown, N.J.

The 400,000-square-foot rectilinear office building offered little natural light and poor accessibility. Perkins+Will cut into the existing office building and created a large, day-lit courtyard. The designers then created a series of glass-enclosed pedestrian bridges that cross the courtyard. Inside, office spaces along the window-lined perimeter of the building were removed to create a glass wall and pedestrian corridor.

Additionally, each of the center’s 18 infusion therapy rooms faces a window. The traditional waiting room has been replaced with dens with lounge chairs and TVs, and libraries with stocked bookshelves and iPad bars. There are three entries: one for general use, one that serves radiology and oncology patients, and one dedicated to caregivers, practitioners and other hospital staff.

The center is now open.
