In suburban Minneapolis, this award-winning addition/renovation uses daylight for its physiological healing impact. Daylight organizes the movement throughout this home and sets the stage for all daily activities from the early shower to cooking of a home meal and arrival of the guests. Ample daylight guides the day activities while at night its absence transforms the house into a relaxing environment. Daylight is used as the main spatial organizational element connecting the occupants to the natural environment. A synchronizing signal daylight sets the occupants natural rhythms.
