1201 F Street, NW is a 230,000 square foot, new construction office building in downtown Washington, adjacent to historic districts. It exhibits a distinctly urban identity that embodies an elegance resultant of design skill rather than extravagant materials.  Unique in the area is its essentially vertical rendering, emanating in part from its unusual masonry to glass ratio.  The lush façade detailing and the use of limestone throughout lends an inherently sensuous, sculptural richness.  The idea that proportion is almost the definition of art and architecture is evidenced throughout the project. Certain massing considerations were taken to capture the idea of a ‘jewel’ in a setting.  The body is classically tripartite not only in a vertical, but horizontal sense as well.  The carefully considered "plaid" of vertical and horizontal elements, scaled in proportion to function, accomplishes a vigorous cohesion, with an emphasis on the towers which crown the site.
