CHICAGO—ExteNet Systems Inc. has just decided to expand at its suburban Lisle headquarters for the fifth time. This expansion adds 11,000 square feet and means the telecommunications firm will occupy more than 40,000 square feet in the Lisle Executive Center at 3030 Warrenville Rd., according to officials from Boxer Property, the owner.  

The Lisle-Naperville market has recently seen a number of small- to mid-sized firms expand, and this has helped drive absorption and push down its vacancy rate, according to Colliers International. In the first half of the year, tenants absorbed another 123,302 square feet, and rents have gone from $19.94 to $20.40 in the past year, the firm found.   

“ExteNet continues to invest in the Chicagoland economy,” says Dan Timm, chief financial officer and executive vice president of ExteNet. “We have created 65 new jobs in 2016 itself and to accommodate our growth we have decided to expand our headquarters. The prime location alongside the amenities ensured by the ownership group were key reasons for our decision.”  

Darrell Herschler of Boxer and Fred Ishler from Transwestern represented the landlord and worked with Todd Schaefer of JLL, who represented ExteNet.

Lisle Executive Center is connected via glass atrium to the Sheraton Lisle Hotel, a property not owned by Boxer, but which does offer tenants and guests access to a variety of amenities including a large conference center and dining options.
