Habitat Horticulture installed California's largest indoor living wall in the heart of San Francisco's south financial district at Foundry Square III. Home to the Neustar and LinkedIn headquarters, Foundry Square III is also lushly inhabited by 12,500 plants that cover the publicly accessible lobby. The stunning living wall was designed with sustainable, water-saving features that helped the building achieve LEED Gold status.
Designed by Habitat Horticulture’s David Brenner, the Foundry Square III’s lush green space spans two living walls. The first wall comprises 1,426 square feet of monochromatic greenery planted with Philodendron cordatum, Geranium cantabrigiense ‘biokovo’ and Asplenium bulbiferum, and serves as a backdrop for white bronze statues. In contrast, the second 1,027-square-foot wall is planted with 23 different plant species and offers greater variation in texture, color, and volume. The plants were specially selected for their ability to extract toxins from the air, such as the Philodendron cordatum’s effectiveness at filtering out formaldehyde and VOC’s.
Both living walls were created with two layers of geo-textile growing felt made of 100% recycled plastic bottles (PET). Drip irrigation provides water and nutrients to the plants, and the excess water is collected, filtered, and recirculated back into the system.
