On the opposite bank of the Sumida River lies the Asahi Beer headquarters (1989), a strange building with a golden sculpture mounted on top of a granite-plated black box. It was designed by Philippe Starck, and completed in 198g when the Japanese economy was still going strong. The sculpture, with no clearly defined use, is a clear representation of its time. Today, the building is known as the 'golden poo', a reference to the shape of its crowning object.
To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again."
Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.
“It is demonstrably true that things cannot be other than as they are. For, everything having been made for a purpose, everything is necessarily for the best purpose.” — Professor Pangloss
So: it is perfectly true that contemporary traditional architecture tends to be structurally dishonest. But traditional architecture has always tended to be structurally dishonest. So if this is what makes contemporary traditional architecture pastiche, then most traditional architecture has been pastiche since the faux timbering of the Parthenon. Contemporary traditional architects have most of the great builders of our history as their companions in guilt.
