A broker for the firm says his company is confident 61 No. Beacon St. will lease quickly, especially because a tenant can begin moving in as early as November. The Hub's record low office vacancy rate has companies scrambling to find adequate quarters, particularly local high-tech firms that often find their space needs growing exponentially.

The New Balance property has many attributes welcomed by new age technology companies, according to C&W, including high ceilings, oversized windows and a brick-and-beam interior. "It's very desirable space," says the broker, noting the property is located less than two miles from Downtown Boston. New Balance will move into its 120,000-sf headquarters during the fourth quarter.
