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
It took two decades for HGTV and its ilk to streamline the process of creating design hegemony — to perfect the concept of having multiple shows congeal around the same aesthetic rather than let them exist at the whims of their individual hosts, as was more the case in the 2000s. While previous eras of design (think midcentury modernism) were spearheaded by architects, interior designers, and other tastemakers, in the late ’90s, capital-A Architecture lost interest in the home — deconstructivist ideas and new, high-tech forms were better suited to museums and universities — and a coalition of real estate developers, home improvement and furniture stores, and TV decorators stepped in to take their place. The worlds of high culture and popular consumption in residential design have never been more separate, and, in this critic’s opinion, both suffer as a result.
