Blueprint Post Production has bought the DES Building Park in Toluca Lake for $13 million, according to Charles Dunn Co. of Sherman Oaks. Blueprint, which provides production and post-production space with offices, editing bays, online and audio finishing suites for the television and film industry, bought the three-building, roughly 60,000-square-foot complex at 4142, 4144 and 4146 Lankershim Blvd. from Lankershim Media Center Associates LP. A division of LS Capital, Lankershim Media owns and operates multi-tenant retail and industrial properties. According to Charles Dunn, Blueprint is the office park’s largest tenant and intends to occupy 60 percent of the complex. The park is adjacent to Universal City and close to other production companies. Stacy Vierheilig-Fraser, senior managing director of Charles Dunn Co., negotiated the deal on behalf of both the buyer and the seller.
