A house addition for two artists and their children, this project asserts the independant character of this family while carefully fitting into a neighborhood of modest bungalows near the Kimball Museum in Fort Worth. The original house is left essentially untouched with new spaces built into an independant concrete block settled into the trees in the backyard. On the roof is a treetop sculpture court surrounded with a light steel bougainvillaea trellis. This mysterious space of shade, privacy and birdsong looks out over the night time views of Fort Worth and the Texas sky. The building in constructed out of structural insulated concrete panels and raw steel.
