A symbol of continuity and evolution, the Saint Mark’s Episcopal Church has served its Capitol Hill community since the late 19th Century. Today, a historically conscientious renovation has updated the church’s support spaces to better meet its needs, while sensitively adding to the historic building envelope. The double height parish hall was split to create a second floor office suite and a fully underpinned basement was excavated for classrooms and meeting spaces. Where possible, original architectural elements were salvaged – the original timber trusses were repurposed as column covers and benches and the original maple flooring was reinstalled in the new rector’s office – offering some continuity amidst the change. The completed project is a testament to the congregation’s dedication to their church, a recognized landmark of the Nation’s Capital.
