Dunescape was a temporary structure built in 1999 by Shop Architects for MoMa PS1. The firm Shop Architects, was created in 1996 by Christopher Sharples, William Sharples, Coren Sharples, Gregg Pasquarelli, and Kimberly Holden in Manhattan.
MoMa PS1 was created in 1971 by Alanna Heiss and is a nonprofit organization supporting urban art and restores buildings. In 2000, PS1 joined with The Museum of Modern Art. They hold an annual architectural competition. Dunescape was the first winner of the competition.
The requirements for the structure were that it needed to provide shelter, water, and seating for crowds. The architects had a budget of $80,000 and a triangular courtyard of 10,000 square feet to work with. The structure also had to be able to be installed quickly.
