The Hills at Vallco silicon valleyDesigns for the world’s largest green roof have been unveiled for the space between Apple’s Infinite Loop headquarters and the Apple Campus 2 in Cupertino, California. Rafael Viñoly Architects and OLIN Landscape Architects will head up the design of a 30-acre elevated community park as part of Sand Hill Property Company’s $3 million renovation plan for the Vallco Shopping Mall, The Hills at Vallco.

The project will transform the outdated, half-empty shopping center into a sustainable, walkable, and bikeable mixed-used community. It will be a hybrid hub of downtown-style retail and office buildings as well as hundreds of rental homes, and parking will mostly be tucked underground. An open space preserve that Sand Hill is calling the “largest green roof in the world” will be built above and around the mall’s buildings at street level.

The estimated $300 million green roof will add much needed open space and recreation to the eastern end of Cupertino. The space will be open to the public and feature a 3.8-mile trail network as well as vineyards, orchards, and gardens with native, drought-tolerant plants.

Aiming for LEED Platinum, the highest certification possible in environmental design, the developer plans to partner with local water agencies and providers to extend recycled water to the site for irrigation, heating, and cooling systems.

Anchored by two town squares within a street grid, The Hills at Vallco’s retail and commercial spaces will cater to a variety of residents and on-site office workers. Some popular Vallco attractions will be retained, such as the AMC movie theater, ice rink, bowling alley, and fitness club–all of which will help them create a family-friendly atmosphere within the district.

Sand Hill is even throwing in $40 million worth of amenities and funding to local school districts, and will spend over $20 million to build a new 700-student elementary school if the project is approved by the city.
