As work and work habits change and the definition of workplace expands, designers are re-thinking the traditional office, moving closer to a seamless integration of work, leisure, and art. The Pretend Store was an experimental pop-up that for one month in November 2013 provided alternative workspace for individuals and teams interested in stretching the boundaries of traditional office design. Using recyclable cardboard building blocks created by O+A, each participant assembled a unique work environment, a taxidermy studio, an architect’s office, a toy manufacturer’s sewing room and gallery. Whatever the need, Pretend Store’s occupants customized the space to meet it and worked there for a day, three days, a week. An exercise in creative adaptation, green building and collaborative planning, Pretend Store demonstrated the energy that is generated when a community comes together to look at work habits and work spaces with new eyes.
