HHL Architects acted in the multiple role of curator, designer, and fabrication partner to create an exhibition of more then 70 art glass windows from the Darwin D. Martin Estate, originally constructed from 1903-1906. The goal of the exhibition was to promote a greater understanding of the architectural importance of the National Historic Landmark. The structure is a full, abstracted "Slice" through the Martin House.
