Facebook unveiled its plans for a massive new campus on Friday in Menli Park which will be designed by Frank Gehry, a renowned architect who has won plaudits for metal-sheathed works like the Walt Disney Concert Hall in Los Angeles and the Guggenheim Museum in Bilbao, Spain. Facebook will submit plans for the site to local city officials for approval on Monday. The designs depict Gehry's vision of a single-story, hangar-like building covering
420,000 square feet, or roughly the area of eight football fields combined under one roof.

Facebook declined to reveal the development's projected cost, saying only that it would fall in line with other Silicon Valley office buildings of a similar size. Facebook intends to shift thousands of software engineers, designers and product executives who work directly on the world's No 1 social network to the new building, which is on the opposite side of a highway from the company's existing campus and near a rugged stretch of the San Francisco Bay waterfront. Business executives and support staff will remain in its current offices, while a tram will shuttle employees back and forth through an tunnel connecting the two work sites. Despite its massive area, the new structure will have few interior walls and instead resemble a minimalist warehouse with an open layout, so the social network's engineers and designers can easily collaborate on projects, according to a company blog post by Everett Katigbak, an environmental design manager. Scattered around the building will be numerous cafes and a restaurant and a garden will nearly span the entire roof.
