"We plan to build add another 30,000 sf on top of the existing10,000-sf historically certified single-story shell next to thePECO building," he says. "We're marketing it as a build-to-suit forlease or sale. The 'as is' selling price for the shell is $1.5million," he says. "A buyer could redevelop and expand itthemselves or contract with us to do the work. At today's prices,the rent rate would be $25 per sf."

Currently, both properties carry the same 2501 Seaport Dr.address. The larger, completed building, "including contracts outfor signature," Kelley says, is 94% leased at a rental rate of$21.50 per sf.
