Sterkel's design for IK Lab continues the environmentally friendly spirit of the resort. Tree branches support the wavy canopy, while smaller sticks arranged in a diagonal pattern allow light to filter through. Large, round windows perforate the interior, and the floor is covered with a local, vine-like plant called Bejuco wood.
