The Lafayette Building located at a prominent corner overlooking Lafayette Square across from the White House

Floor plate Occupant Efficiency Study comparison of - (left) floors required by historic preservation to retain historic circulation principles; (right) increasing occupant optimization while increasing work space options maintaining only "historic central core" utilizing portals at transitions to open office plan areas.
Portals - transitions from remaining "historic" preservation central core to "open office planning".
Portals - Left: existing historic core and circulation; Right: rendering of portal transition from historic core to open office plan.
Portals created a “contemporary interplay” with the building’s original 1940’s appearance and detailing.Incorporation by an overhead concealment of “cross-over” routing of building systems below low beam elevations at locations of removed existing corridor.
Concept Planning & Coordination: strategic design decisions to provide updated building system required by codes and to provide current technologies. Proposed systems vertical cores highlighted; located based on constraints of above ceiling structural barriers for lateral system runs.
Concept Planning & Coordination: existing documents and existing conditions analysis with study to integrate modern building systems within limitations of the existing structure. Follow-through of design concept (floor plan highlighting mechanical cores & field data) with design goals to optimize ceiling heights & natural day-lighting (concept section and CD's detail section).
