Cupertino May Replace Its Dying Shopping Centre With the World's Largest Green Roof 

By Kelsey Campbell-Dollaghan on at

Like most American suburbs that were built in the 1950s or 60s, Cupertino has a once-hopping mega-mall shopping centre that’s now a crumbling eyesore. But unlike most suburbs, Cupertino is now a very affluent hub of Silicon Valley capitalism.

Cupertino’s shopping centre is called Vallco, and it was built in the 1970s. For a long time, it was one of the biggest, busiest in the region. Yet as shoppers migrated onto the internet—irony!—Silicon Valley’s major shopping centre went into decline. “Macy’s closed in March 2015, and the lower level of the building has been shuttered for more than a decade,” says Sand Hill, the developer behind a project to redevelop Vallco, “with Sears recently announcing their closure this October, occupancy will fall below 50 per cent.”

That’s a very, very common story in American suburbs, of course. But unlike typical dying shopping centres, Vallco occupies some very, very valuable land. Just one major street over sits the construction site where Apple is building its new campus. A few miles north sits Mountain View.

And so this week, Sand Hill announced its plans for the ageing shopping centre: “The Hills at Vallco,” a massive mixed-used development that will be covered by a 30-acre green roof, topped by “3.8 mile trail network for jogging and walking, vineyards, orchards and organic gardens, an amphitheatre, children’s play areas and a refuge for native species of plants and birds.” That sounds lovely, though, building an artificial park featuring orchards during a historic drought will certainly be a challenge.

Supporting all of these amenities will be a vast network of structures, including housing, retail, and office space arranged in a city-like “grid.” Infilling the blocks will be more public space, while walkways overhead connect the park spaces to one another. The whole development will be planned and designed by Rafael Viñoly (yes, the Rafael Viñoly behind the car-melting death-ray skyscraper in London) and OLIN Landscape Architects.

But the focus here is on the utopian-tinged roof space, which seems to be producing its own vintage in some of the developer’s renderings. Also featured? people working on laptops around individual fires while people watch Pixar’s Inside Out in a park:

There’s a good reason Sand Hill talks so much about the park and less about the development. As Silicon Valley Business Journal pointed out yesterday, this is a city that has been very cautious about approving big new developments in the past.

Whether or not the Hills makes it through the fraught planning process intact, it’s pretty amazing to see the scale of new architecture and planning ideas being proposed in this region right now. From Google’s planned pseudo-utopian headquarters to Facebook’s own giant tree-covered box building, it’s an interesting time to be an architect and developer in Silicon Valley.
