The San Blas healthcare center works with the idea of a “placeless building” as a very effective and categorical kind of way to develop a functional healthcare program located in an almost irrelevant environment. To underline the space's richness in its interiors, the projects relies on the corbusian idea of “conciliation of contraries”: a hermetic and massive concrete exterior is put into contrast with an open and light interior. The program for the health center is implemented extensively on a single floor. The different rooms of the program are organized on a loose irregular orthogonal grid, where thirteen patios with blue ceramic are arranged in a zigzag pattern between the public and private rooms along three parallel (non)-corridors. The nonexistence of openings in the vertical planes of the exterior skin, makes the interior-exterior relation of the building to be perceived vertically, as if stretching out to reach the sky. The transparency and mirroring qualities of the glass create at the same time multiple visions by reflected symmetry. Similarly, the reflective qualities of the vertical walls of blue tile arranged in a fish scale pattern help create a spacious and luminous interior atmosphere, almost as if the sky was brought inside the building.
