With a Bachelor of Architecture from UT Austin, Britton practiced architecture and environmental design in several firms. After licensing and LEED accreditation, Britton wanted more for the built environment, which led him to pursue a Certificate in Sustainable Building and Design at Yestermorrow, and a Master of Environmental Design from Yale. He examined urban and landscape history, including the reuse of abandoned buildings and toxic industrial landscapes. After graduating, Britton stayed at Yale to teach advanced design and urban history. In his practice today, Britton focuses on renovations and restorations, as well as designs for gardens and landscapes. He also writes about and photographs urban landscapes, infrastructure, and industrial relics. In addition to his practice and teaching, Britton serves on the board of directors of several community- and ecologically-focused non-profit organizations in Vermont and Connecticut.
