What makes architecture engaging? And what purpose does engaging architecture serve? Artists Arakawa and Madeline Gins answer both of these questions with their Bioscleave House, an indoor playground of sorts aimed to help people live longer and healthier. Filled with bright, energetic colors and playful, undulating floors, the house provides an environment that constantly stimulates the body and mind. A bold departure from the predictable elements we associate with ordinary homes, the purpose is that visitors and inhabitants alike will always be learning to adapt and will therefore maintain a certain youthfulness.
