During the twentieth century in Denver, typically only one building was constructed each decade in the greater Civic Center area. That's changed, though, and since 2000, we've seen no fewer than eight new landmarks. Add to this exalted group the Denver Police Crime Laboratory, designed by the Durant Smith Group. Though relatively small in size, it's big in visual appeal, with folded plate walls zigzagging and cantilevering out above the ground, all carried out in mirrored glass, masonry and panels. And although the designers showed a clever disregard for symmetry, they gave the building a spectacular sense of balance. Only employees can get inside the crime laboratory, which is too bad, because a pair of impressive suspension sculptures, "Suspect" (which can be seen through the windows on West 14th Avenue) and "Bullet," both by Cliff Garten, have been hung above the main floor.
