Kahn Stool is a minimalist stool created by Barcelona-based designer Sanna Völker. Kahn is an architectural piece of brutal delicacy. A study of the design philosophy of Louis Kahn, and a tribute to the architecture that shaped his work. A journey to the ancient monuments of Egypt, Greece and Rome, expressed in a travertine stool forged by history, craftsmanship and nature. The stool is crafted in Roman travertine, from the same block as the latest angel for Sagrada Familia.
