To illustrate Ken Fulk's living and design philosophy, let's simply say: When asked to wear a top hat for this story, he had one in his closet. Fulk's brand of interior design is one part skill, one part fantasy and one part pure showmanship. Following him around this Belvedere home he designed, it's clear that he's a member of that rare breed of architects and designers (from Frank Lloyd Wright to Barbara Barry) who do more than just create a beautiful home; they craft a lifestyle. And in Fulk's case, he can do it, forgive the pun, at the drop of a hat.
