Timed with the arrival of spring, a soft, vegetal landscape is embraced by a pond at Vondelpark. A floating labyrinth of flowers, grasses, and shrubs, Sprouts draws from Amsterdam’s houseboats and riparian infrastructures, extending the park into the water. Built from urban tree mulch, packed into salvaged oil drums and inoculated with mycelium, Sprouts decomposes over time, releasing nutrients back into the pond. Designed to transmogrify—embracing entropy as a generative force and dissolving into cycles of growth and return, the pavilion is not an inert structure but an agent in the park’s composition, ephemeral yet integral to its seasonal rhythms.
