Stanford’s Windhover Contemplative Center – Art, Nature, and Rammed Earth Architecture
Opened in 2014, the Windhover Contemplative Center is a spiritual retreat and a highly sustainable building on Stanford University’s campus.
The center is housed in an innovative construction, mostly made of rammed earth and wood, designed by San Francisco-based architectural firm Aidlin Darling Design, founded by Joshua Aidlin and David Darling in 1998.
Combining an art gallery and a meditation space, the 4,000-square-foot / 370 square-meter center takes its name from the Windhover series of paintings by Californian artist and Stanford University’s professor Nathan Oliveira (1928-2020).
The series, that comprises six monumental oil paintings, is on show in the pavilion not as if it were in a museum but to inspire and complement the spiritual experience of the visitors in what its architects describe as a “chapel-like center (that) provides a refuge from the intensity of daily life and a space for quiet reflection”.

The paintings hang on exposed rammed earth walls that provide them a fascinating and totally appropriate backdrop. To get wall colors (mostly in the brown family) that didn’t interfere with those of the paintings, as well as to achieve the required structural strength, local subsoil was combined with sand, gravel, rhyolite powder, decomposed granite, and Portland cement.
After being poured into the formwork, the mixture was pounded to four-inch courses to create striated rammed earth walls up to twenty feet tall and two feet thick. Along with rammed earth for the walls, stained oak and hemlock were used for cladding ceilings and floors, weathered steel for various elements including the window frames, and locally-sourced stone for the external benches and other decorative elements.

When walls, ceiling, and floor encounter a glass opening, they usually extend outwards, thus creating a geometric interplay that emphasizes the building’s openness and relationship with the landscape. Designed by Andrea Cochran Landscape Architecture, the center’s outdoor area features a large reflecting pool, a circular labyrinth, an open-air contemplative space, a tall bamboo line, and an old oak grove.
Throughout the entire site, water is a recurrent feature as a reflecting pool to the south of the main building and two small fountains, one installed inside the building and the other in the central patio.

While the massive rammed earth walls provide a great thermal mass for temperature stabilization, vegetation, together with roof overhangs, creates passive shading and regulates the intensity of light in the indoor environment. Sustainable solutions for the Windhover Center also include skylights with motorized louvers, radiant-floor heating and cooling, and natural ventilation. Finally, a large part of the materials used – including the soil for the rammed earth walls and the stone used for the center’s benches – were sourced locally.
