"Both of these companies needed more space because their businesses were expanding," says John Zogg, managing director of leasing for Crescent Real Estate Holdings LLC, the owner of Fountain Place.

Tenet Healthcare moved its corporate headquarters into Fountain Place in October 2009, signing a 10-year lease for 164,963 square feet. The company recently expanded its lease by 11,220 square feet and now occupies 176,183 square feet. Zogg tells GlobeSt.com that the space was vacant, allowing Tenet Healthcare to move in quickly.

Kirby White, director of leasing at Crescent represented the landlord, Crescent Fountain Place, L.P., while Phil Puckett and Chris Herrmann of CB Richard Ellis represented Tenet Healthcare.

Similarly, Wells Fargo Bank previously occupied 92,020 square feet and signed a new lease for 7,487 square feet, bringing its total to 99,507 square feet. Wells Fargo was represented by Wells Fargo's lease negotiator, Bob Williams. White represented Crescent.

With the lease expansions, the 1.2-million-square-foot Fountain Place is 83% occupied, according to Zogg.

"When Hunt Oil moved out last year, they left us more than 300,000 square feet to fill," Zogg says. "This building was full for a long time and now we're chipping away at the former Hunt Oil space."

The 60-story Fountain Place is a downtown landmark, located on the northern edge of Dallas' central business district. The asking rental rate for the tower is $23 to $28 per square foot, full-service plus electric.

"Across our portfolio, we're seeing expansion by our existing customer base, as well as signing leases with new tenants," Zogg says. "We're cautiously optimistic about where we are in the market."
