The Reserve, a nearly 400,000-square-foot creative office campus in Playa Vista, was sold last week to Atlanta real estate fund Invesco for $316 million. At about $790 a square foot, the price was among the highest paid for an office property in the region.

The seller, a joint venture of Santa Monica’s Worthe Real Estate Group and San Francisco’s Shorenstein Properties, bought the property for about $46.5 million in 2011, according to county records.

Roughly $30 million was invested to transform the property – a former U.S. Post Office distribution center built in 1971 – into a creative office campus, boasting sand volleyball courts, a dog park, car wash and a fitness center, among other amenities.

Since the extensive renovation, the office park has been a hit. The developers attracted tenants like TMZ, Microsoft Corp., Sony Playstation, Verizon Communications and Team One, an advertising agency.

Representatives of Worthe, Shorenstein and Invesco could not be reached for comment.
