Was designed by I.M. Pei in 1961 and completed in 1966. The laboratory is located in Boulder, Colorado along the Flatirons hill on the Table Mesa. The building has a pinkish resemblance to blend in with its surroundings. I extremely love delicacy that went into the design that gives it that maze like structural feel with all of the geometric shapes that the structure has. This is a very unique building due to the fact on how well it forms in with the environment around it which is what I really like most about it.
