The Niteroi Contemporary Art Museum (MAC) in Rio de Janeiro, Brazil

"The MAC hangs over the water, a simple collection of lines and curves inspired by flowers growing in the landscape of Rio de Janeiro," Peter Exley said. "A beautiful, sweeping pink line marks the pathway to the entrance of the building. It's the most charming arrival to any building: unpretentious, gentle, poetic, and steeped in anticipation."

Exley is a professor at the School of the Art Institute of Chicago and the founder of Architecture is Fun.
