The new strategy give's Alexandria a much larger tenant pond tofish. The company's regional market director, senior vice presidentSteve Richardson tells GlobeSt.com the casting of the wider net isnot a response to a slowing of interest by life science relative topro forma lease-up or development schedules, Richardson says.

"The reasoning is much more along the lines of the reality herethat traditional Silicon Valley tenants such as Google, Yahoo,Microsoft, Intuit, Adobe and Salesforce.com are expanding up intoSan Francisco in order to attract talent," he says. "We thought itprudent to look at our holdings and decided that a mix of a few ofthose select tenants would be good for them, good for the lifescience companies and good for UCSF."

Alexandria's Mission Bay campus is thus far fully entitled forsix buildings totaling one million sf beyond the one completed latelast year, 1700 Owens, a 165,000-sf laboratory/office building(1700 Owens) that is now 80% leased to life sciences companies.Under construction is 1500 Owens, a six-story, 165,000-sflaboratory/office building that is scheduled for delivery in late2008. Pre-construction work is under way for twin five-story,105,000-sf buildings. Next to those is a planned 200,000-sf highrise that is awaiting a build-to-suit deal.
