In the heart of downtown Brooklyn, Delson or Sherman has designed the borough’s largest wellness center.  Joining two disparate clinics, the architects made one big multi-purpose space.  To do so, they had to manage multiple parties with tight deadlines and tighter budgets.  But this means visitors can now get Pilates classes, massage, chiropractic, and physical therapy all under one roof.  Sunny open loft areas now face wide views of the park, while treatment rooms and offices are cozy and private.  Movable panels divide the spaces for individual care or group classes.  The architects exposed ducts and heavy timber beams but jazzed up the look with vivid wallpaper and paint.
