Over 800,000 square feet of office space changed hands Monday at Warner Center when Houston-based Hines purchased the LNR Warner Center complex from RREEF North America for about $300 million.

Hines, a privately owned worldwide real estate firm, won out over several bidders for the site, built by Lennar Partners between 2001 and 2005. It includes 808,274 square feet of office space and is 98 percent leased, with tenants such as NetZero and Univision Music.

“We are strong believers in Warner Center as a key suburban core market, which is extremely important to the entire valley of Los Angeles and to the greater Los Angeles area from a business perspective,” said Colin Shepherd, a Hines senior vice president.

Shepard added that Hines has no plans to renovate the complex, because it already serves its existing tenants well. A representative from RREEF North America declined to comment, citing a confidentiality agreement with Hines.

Lennar Partners still owns other property at Warner Center and plans two more office buildings. Building “D” is under construction with a targeted opening date of fall 2007. Building “E” is slated to open in spring 2008; construction has not begun on that project. The buildings will total an additional 500,000 square feet of office space.

RREEF North America is a unit of RREEF, a fund manager owned by German Deutsche Bank. RREEF North America manages more than 750 properties totalling 205 million square feet.
