As a result, “I don’t expect this year we’ll end up with 280,000 sf,” he says. But a decent second quarter, with 50,000 sf to 60,000 sf of leasing activity, is expected. The park had more than 280,000 sf in leasing activity last year and approximately 300,000 sf the year before.Airport Corporate Center contains 11 buildings, four of which are class A office buildings that total 632,680 sf; two of which are class B office buildings that total 173,810 sf; four of which are flex/office showroom buildings that total 168,235 sf; and one of which is a 43,752-sf warehouse building.
