One Capital Management plans to relocate within Westlake Village and double its existing space by the end of the year, according to Daum Commercial Real Estate Services. The global investment management firm has signed a lease to take 9,000 square feet for eight years at 3075 Townsgate Road, which sits within the second phase of the Westlake Park Place office park, and plans to move there by December, Daum said. Currently, the firm is at 2945 Townsgate Road in Westgate Park Place Phase 1, where it has been since 2011. Daum Executive Vice President Mike Foxworthy said One Capital is one of several tenants of the office park experiencing growth and expanding as a result. He brokered the deal on behalf of One Capital and property owner Amstar in Denver, along with Daum Vice President Craig Cahow. “Leasing activity has been exceptionally strong for Phase II, which encompasses approximately 239,000 square feet and is already 85 percent leased,” Foxworthy said in a statement. Phase II’s three buildings finished construction last year. Phase I finished in 2008. Other tenants of the building include Stifel, Nicolaus & Co. Inc. and Summit Financial Consultants Inc. Summit, an independent hybrid registered investment advisor firm, relocated to the office park in the spring after merging with Sorensen Wealth Management later last year. Other tenants in the office park include Dole Packaged Foods and PennyMac Loan Services, according to Daum.
