Nature has a strong presence at Kálida. The 8,600-square-foot, two-story building was designed with more gardens than interior space and has a floor plan that resembles a blooming flower. The concrete-framed center appears solid yet porous, with latticework of concrete, solid brick, and ceramic tile laid in inventive repeating patterns that allow for shadow and privacy. Though its facades could not be called quiet, the building does have a camouflage factor: when seen from the hospital, the roof, finished with green and yellow tiles, reads as part of the vegetation and therefore does not compete with the adjacent historic site.

Organic and tactile, the exteriors and their sinuosity correspond to the fluidity of the interiors, which flow to form private corners as well as a common space for impromptu meetings. Kálida Sant Pau blurs servant and served spaces; circulation doubles as places to occupy. Large window compositions—with their handmade wood louvers and EMBT’s signature iroko wood carpentry—fill the interior with daylight and link it so thoroughly to the surroundings that it becomes difficult to draw a line between inside and outside. It is this ambiguity that makes the building unexpected. In a sleight of hand, the architects have also created a place that is both multifunctional and very specific. While flexible programs often sacrifice a sense of self in the name of adaptability, here spaces have a strong identity while still being able to serve a range of uses—intimate meetings, say, or larger assemblies.

The crafted brick facades reinforce the notion of genius loci, telling a story of handmade architecture and revealing the human presence in construction. A pergola of powder-coated steel with a lattice of American tulipwood extends the fluidity of the interior and the flowerlike floor plan outside. Inside, finishes coexist like a patchwork: the wood millwork, vaulted terra-cotta ceilings, and, underfoot, colorful ceramic and oak living side by side on the floors designed by Milan-based architect Patricia Urquiola. Commissioned and supported by a handful of foundations, the financing of this pavilion (which had a construction cost of $2 million) is also a work of craft.

Kálida Sant Pau is an opinionated building that speaks up. Its strength is in its showing how dialogue—between diverse materials, historic and new architecture, inside and outside, and solidity and porosity—can create a healing environment.
