Mushroom Pavilion, designed by OMA / Shohei Shigematsu, joins the art and community installation campus founded by Mexican artist Bosco Sodi, located within the expansive 26-hectare natural landscape of the Casa Wabi Foundation, nestled between the mountains and the coast of Oaxaca, Mexico.

The proposal marks the first work built by OMA in Mexico, presenting a space for mushroom cultivation that fosters exchange between gastronomy, art, nature and local communities through a "Food and Community Incubator", ideal for all kinds of activities for residents, visitors and the foundation. 

The pavilion designed by OMA / Shohei Shigematsu maintains a stepped, ellipsoidal form created to optimize the interior organization of the mushroom cultivation and function as a circular amphitheater, allowing the entire cultivation process to be viewed. Inside, the dome is divided into three chambers surrounding a central space: the fruiting room, the incubation room, and the storage room.

The base of the volume curves inward to minimize the pavilion's contact with the ground, preserve the natural landscape as much as possible, and allow the native guayacán tree to thrive. In the central space, an oculus opens to the sky, and additional openings are created around the lower perimeter to allow natural light to enter. Finally, at the top of the steps, a platform and a portal offer views of the ocean.

Regarding the materiality of the design, the concrete structure is composed of troweled concrete poured in situ, with stamped burlap on the exterior and a high iron content. Regarding the appearance of the "Mushroom Pavilion", it is expected that due to the natural conditions of the site, the pavilion will rust and change over time.

Project description by  OMA / Shohei Shigematsu

The Mushroom Pavilion is now open at Fundación Casa Wabi, joining the campus of art and community facilities founded by Mexican artist Bosco Sodi. The project marks OMA’s first built work in Mexico. Located in the foundation’s sprawling, 65-acres of natural landscape between the mountains and Oaxacan coast, the Mushroom Pavilion is a space for cultivating mushrooms while fostering exchange between food, art, nature, and local communities.

Conveying its simple yet important function, the pavilion is a basic, ellipsoidal form created to optimize interior organization for growing mushrooms. Within, the domed interior can be divided into three chambers – fruiting room, incubation room, and storage – encircling a gathering space at the heart of the pavilion. The lower half of the bowl is stepped, like an amphitheater in the round, to make shelves for handmade terra cotta mushroom pots crafted by local artisans. The stepping and elliptical form create a panopticon viewing experience, rendering the mushroom growing process visible in its entirety.

An oculus opens up the central space to the sky and fills the cave-like interior with light, while additional openings around the lower perimeter enable natural ventilation. A platform and portal at the top of the steps offer views above and beyond the natural brush to the ocean. The three-dimensional volume curves inward at its base to minimize the pavilion’s contact on the ground, preserving the natural landscape as much as possible and allowing the native guayacan to thrive.

The concrete shell is composed of troweled and poured-in-place concrete, burlap stamped on the outside to retain the site’s high iron content water. Conceding to the natural elements, the pavilion will rust and change in appearance over time.

“Working with Bosco Sodi and Fundacion Casa Wabi, we conceived a pavilion for the very specific function of mushroom cultivation while offering a space for people to come together. The result is an incubator of both food and community that’s spatially fit to support all types of activities for the locals, visitors, and the foundation. As a Japanese architect, it was especially meaningful to contribute an art campus guided by Japanese philosophy and spatial traditions.”

OMA's buildings and masterplans around the world insist on intelligent forms while inventing new possibilities for content and everyday use. OMA is led by ten partners – Rem Koolhaas, Ellen van Loon, Reinier de Graaf, Shohei Shigematsu, Iyad Alsaka, David Gianotten, Chris van Duijn, Ippolito Pestellini Laparelli, Jason Long and Michael Kokora – and maintains offices in Rotterdam, New York, Beijing, Hong Kong, Doha and Dubai.

Responsible for OMA’s operations in America, OMA New York was established in 2001 and has since overseen the successful completion of several buildings across the country including Milstein Hall at Cornell University (2011); the Wyly Theater in Dallas (2009); the Seattle Central Library (2004); the IIT Campus Center in Chicago (2003); and Prada’s Epicenter in New York (2001). The office is currently overseeing the construction of three cultural projects, including the Musée National des Beaux-arts du Québec and the Faena Arts District in Miami Beach – both scheduled for completion in 2016 – as well as a studio expansion for artist Cai Guo Qiang in New York. The New York office has most recently been commissioned to design a number of residential towers in San Francisco, New York, and Miami, as well as two projects in Los Angeles; the Plaza at Santa Monica, a mixed use complex in Los Angeles, and the Wilshire Boulevard Temple.

OMA New York’s ongoing engagements with urban conditions around the world include a new civic center in Bogota, Colombia; a post-Hurricane Sandy, urban water strategy for New Jersey; the 11th Street Bridge Park and RFK Stadium-Armory Campus Masterplan in Washington, DC; and a food hub in West Louisville, Kentucky.
