Architecture firm NADAAA planned a striated addition to a brick neo-Georgian house in Boston with the owners’ primary goal in mind: to engage with the outdoors year-round. The walls of the rear kitchen and living space are virtually all glass, allowing sight lines to the existing gardens and new pool house through a series of framed vignettes onto the backyard landscape. The glass box is bookended by uniform “fins” that mark the edge of each picture window, as shown here. Photo by John Horner.
