"We're seeing a lot of people coming through," acknowledges BealVP Robert Doherty, the most recent being NextJump, a burgeoningtechnology firm that will relocate from smaller suburban quartersinto 22,000 sf on the fourth floor of Building 200. The seven-yearpact will repopulate space previously occupied by DraperLaboratory, which is joining long-time occupant Genzyme Corp. indeparting for a custom-built operation. Genzyme is giving up about165,000 sf in the 11-building, 675,000-sf complex, but Dohertyreports solid progress backfilling that space.

Assembled from a one-time industrial facility that dates to thelate 19th century, One Kendall Square offers an eclectic mix oflaboratory, office and retail in a series of interconnectedbuildings and featuring courtyards and other unique elements. Theenclave also includes a 1,500-vehicle parking garage andmulti-screen theater.

The NextJump pact brings Building 200 to full occupancy.Buildings 600 and 700 have the most empty space with about 130,000sf, but Doherty says he is encouraged from the response byprospective tenants. One reason could be super-tight vacancies inthe core East Cambridge market. According to Q1 figures from JonesLang LaSalle, the 10.4-million-sf Cambridge office market has avacancy of just 8.8%, while the 6.9-million-sf lab sector is at10.2%.
