Intertek, an equipment testing firm, has inked a long-term lease for the balance of a 150,000-sf flex building at 1809 10th St., setting a plan in motion to vacate 420 N. Dorothy Dr. in nearby Richardson. The lease requirements narrowed the selection to five buildings because must-haves included staying in the northeast Dallas submarket and fully air conditioned space, Thomas Lynn, president of the corporate services division of Dallas-based NAI Robert Lynn, tells GlobeSt.com.

"They needed to stay near their current facility. They like the area and are happy with their employees," Lynn says, adding heavy power also was on the must-have list. "They are just expanding their business dramatically."

Lynn says the site search began in the summer, triggering a search for more space and image-setting location. The 10th Street Business Park is a two-phase development totaling 658,000 sf set on 40 acres. The project was developed by Dallas-based Miramar Development and is being leased by Michael McCarten and Jeff White, partners in Mark V Commercial in Plano. According to the North Texas Data Exchange, the flex space's quote was $4.50 per sf in a triple net annual rate.
