The Huntington Center office tower at 41 S. High St. will be renovated to lure new tenants and retain existing ones.

Houston-based real-estate investor Hines, which owns the property, has hired Chicago's Hartshorne Plunkard Architecture to help plan and design a rooftop patio, tenant lounge and secure bike storage. Also planned are upgrades such as new lighting and decor in common areas.

The Columbus office of commercial real-estate firm CBRE Group has been hired as the exclusive leasing agent for the building, opened in 1985. A CBRE spokesman said the currency vacancy rate is 15 percent.

In addition to 37 floors of office space, the Huntington Center includes 27,000 square feet of restaurant/retail space, a 1,000-car parking garage and the 29,650-square-foot Capital Club fitness center.
