A pivot door to an architect is like a gull wing door to a car enthusiast; completely unnecessary but capable of transforming the ordinary to the sublime. Originally found in ancient stone building construction, where they were used to conceal secret passageways, pivot doors rotate around a central hinge and were favored by modernist architects like Le Corbusier and Jose Lluis Sert for their ability to sculpt free-flowing space with ease.
