Adaptive Reuse: When architects deploy space, light, and materials to bring modern design into historic structures, they create concretized shifts between moments in time that can be perceptually arresting. We explore 13 plays of history in structures that range from a palace in Beijing to a biscuit factory in downtown L.A.

Engineering News-Record, RECORD’s sister publication, recently published a special feature on “Progressive Project Delivery,” including an opinion piece observing that “Architects Move Belatedly to the Light” and another column, “Could Big Change Happen here?” that warns: “new methods of project acquisition [in Britain]… should send shudders down the spines of American architects and engineers.”
