A nature walk has something for everybody and the concept of winter gardens should be embraced by all.  The rentable square feet per employee is shrinking and collaboration space is growing.

According to the GSA’s “Washington headquarters is completed in 2013, the building will accommodate 4,500 workers — almost 2,000 more than a year ago — because of shared work spaces and telecommuting. GSA Headquarter office will average approximately 80 USF (92 RSF) per person of workspace.”

Alexandria Real Estate Equities has completed most of the work on its 6,000-square-foot winter garden at 75-125 Binney St., the future home of Ariad Pharmaceuticals Inc.
