In a historic neighborhood at the foot of 50-story skyscrapers, this addition to a 1910-era house investigates the condition of living in Atlanta’s dense Piedmont forest, within the city. Horizontal and vertical views are positioned to the surrounding tree canopy and skyscrapers beyond, and rely on the tree canopy for privacy in the dense residential setting. Floor levels are pin-wheeled around a ‘floating’ steel stair - designed without visible stringers to suspend it within the interior volumes - to heighten the experience of residing among the trees.
