Next to the chapel lies a concrete porch of 6.2 m high, holding a beam that extends a span of 9.15 m. This gate symbolically reinforces the idea of a transition from the profane to the sacred, while functionally hosts the sliding glass door that is limiting between the chapel and pond. Thus, when the weather permits, it is possible to open the screen, maximizing the intimate contact of the chapel with its environment. To avoid interrupting the continuity of the water surface, the rail of the screen is slightly submerged, being imperceptible from a distance. This detail seemed very special and original, until I visited Luis Barragán's home studio in Mexico, and discovered where Ando took his inspiration to design that screen.
