A jungle gym is a playground equipment, but also could be a mountain, observatory, and a small house. It resembles a nature that continue existing there, and it is also like an architecture that can be freely customized. “The perfect architecture” where everything is prepared is somewhat suffocating. A jungle gym carries possibility to change its use while preserving its strength. I think of building an architecture as such. The café stands along the coast. The requirements are to make it able to look out the coast from the seating, and to plant a large tree inside. I thought of an architecture with strength that will be consistent with any acceptance, in order to exceed the use of the space as a café and create a place that makes people gather.
