Situated along the River Vltava in a historic district where new construction is strictly regulated, the building is prominently located on a corner across from a public square and a major bridge. The location and Gehry's observations of Prague's "implied towers" and the architectural detail that adorns its buildings were decisive factors in his design. The fluidity of the riverfront facade smooths the transition between its seven stories and the five stories of neighboring buildings. Moving up and down and projecting away from the facade, the windows take on a distinctive presence in a manner first seen in the original 1977–78 renovation of the Gehry Residence in Santa Monica. Striated patterning further enhances the rhythmic effect across the concrete surface. The "body language" of the two towers earned the building its nickname, "Fred and Ginger," after dancers Fred Astaire and Ginger Rogers. Resting lightly atop slender animated columns, the glass-clad tower—its pinched waist minimizing obstructions to the river view from the adjacent building—leans in toward the cylindrical tower. Urbanistically, the towers play the important role of anchoring the public square and forging a connection to the bridge.
