This is a detail of the Royal Ontario Museum’s exterior wall, as seen from the inside. This part of the museum, called The Crystal, was completed just six years ago. If this little slice of dirt and decay were an aberration, I wouldn’t bother highlighting it. But everywhere you look, the same lack of foresight and quality is visible. Walls look unfinished. Space is carved up into awkwardly shaped, unusable chunks, including a couple large areas right near the main lobby. Most famously, the exterior surface had to be reworked extensively because the architect failed to anticipate the implications building a huge sloped exterior in a city that gets nearly four feet of snow per winter.
