Kilroy Realty Corp. has completed three major lease transactions in San Diego with publicly traded life science and biotech companies. The lease deals total 330,000 square feet, and will involve the redevelopment of current office space into life science facilities.

Tandem Diabetes Care signed a 182,000-square-foot lease with the Kilroy, DermTech signed a 96,000-square-foot lease and Sorrento Therapeutics took 52,000 square feet. Nelson Ackerly, senior vice president of Kilroy, said the three leases illustrated the quality and flexibility of the firm's properties, particularly after initial leasing.

Kilroy is actively expanding its life science portfolio. The firm is currently planning construction on Santa Fe Summit, a 600,000-square-foot life science facility in San Diego that it says will meet the growing demand in the market. The development is located in the 56 Corridor. In June, the company also started construction on the second phase at Oyster Point, a premier life science campus on 50 acres in South San Francisco. One of five, the second phase will feature thee buildings totaling 860,000 square feet and represents an investment of $940 million.
