Architecture: Post-War Era / Modern (1945 to the present)
The Modern buildings at the Presidio include the Main Post Gym and the Crissy Field warehouses. Designed as simple buildings which promote function over form, these structures often represent new advances in building technology. The now-demolished Letterman Army Medical Center also fell into this category; it was constructed of pre-cast concrete components. Building 924, the Crissy Field warehouse shown above, exhibits innovative engineering design with its open floor plan and glass curtain walls.
