Naked Concrete
Reston Station OB1, Reston, VA, is a striking 16-story office tower showcasing a unique lateral force-resisting system comprising a diagonalized, exposed concrete exoskeleton. The concrete exoskeleton columns are aesthetic features that support gravity loads and resist lateral loads in the north-south direction. Six shearwalls, located in the core of the building along the elevator and stair shafts, serve as the lateral force-resisting system in the east-west direction. Key design features are summarized.


Butterfly House
The Butterfly House, a residence in Monterey County, CA, provides unobstructed views of the surrounding environment and wildlife.
