The building at CB21 stands apart with a facade of shifting, angled glass panels that create a serrated silhouette against the sky. Originally constructed in nineteen seventy-four as the tower for the oil company Esso, it served as a private fortress for the petroleum industry for decades. The structure underwent a massive redesign in two thousand nine, where architects stripped the concrete exterior to install its current reflective skin. Employees now navigate a lobby that functions like a high-traffic urban street.
