Evidence based design has shown that specific design components and therapeutic elements can benefit patients by improving medical outcomes, reducing stress and elevating the immune system. I intentionally used the colors of Spring to transform this underground doctor's waiting room into a cheerful healing environment.    The carpet tile, a thin stripe with the predominant color of fresh cut grass, is arranged in a basket weave pattern that creates visual interest and hides foot traffic. The PVC-free upholstery on the seating is easy to clean and provides a moisture barrier - an essential for maintaining sanitary conditions in healthcare interiors.   I retrofit the non-functioning fireplace with an electric heating unit with a softly flickering light to add a calming focal point and replaced all of the pharmaceutical literature that used to litter the mantle with live plants and fresh flowers. The mirror above provides a secondary source of light which helps open up the small space.   In an effort to be sensitive to the fact that the doctors serve a predominantly Asian community I highlighted the handmade artwork they brought back from a recent trip to South East Asia with simple white frames and hung the trio directly opposite the front door.    The combination of natural light wood furniture and pale blue walls infuse the space with a sense of renewal and help to enhance the sense of well-being.
