n autumn 2015, Porcelanosa, a Spanish
manufacturer of tiles and kitchen/bath
finishes, opened a new 18,000-squarefoot New York showroom at 202 Fifth
Ave. Occupying the former Commodore
Criterion building, the store required a full
gut renovation to create seven levels within
a building envelope that previously had
only six levels. In contrast, the terra-cotta
exterior is regulated by the NYC Landmarks Preservation Commission and could
not be significantly altered.
The new interior consists of a three-story
public showroom extending from the basement to the second floor and a materials
library for designers at the upper levels.
There are two floors of offices in between.
