MIAMI—As Miami's office market continues to recover, Miami Center, an office tower sitting at 201 South Biscayne Boulevard, is winning its fair share of tenants.

Representing owner Crocker Partners, Cushman & Wakefield has brokered 228,000 square feet of lease transactions this year at the office tower. CushWake senior Director Jon Blunk, senior associate Cristina Glaria, and director Laurel Oswaldhave secured five lease renewals and expansions—including two of the largest office lease transactions in Miami's CBD this year.

This leasing activity comes as Crocker Partners embarks on a $20 million main lobby and building exterior renovation project led by Richard Meier & Partners. Renovations include a new building entrance with a porte-cochère and valet drop-off located on Chopin Plaza; a modernized glass curtain wall system replacing the existing north and west façade; an enhanced multi-tenant monument sign fronting Biscayne Boulevard; and a redesigned lobby with new, modern finishes and refurbished elevator cabs.

"Miami Center has always been the standard for prestige, luxury and convenience in Miami's office market," Blunk tells GlobeSt.com. "Crocker Partners' extensive renovations will only enhance this allure and further drive user interest."

Citibank renewed its 122,000-square-foot multi-floor lease. This is the second-largest office lease transaction in the Miami-Dade market this year and the largest transaction in the CBD, according to CushWake's research. Patrick Duffy of Newmark Grubb Knight Frank represented the tenant.

Shook, Hardy & Bacon renewed its 54,700-square-foot multi-floor lease. According to CushWake, this is the third-largest CBD office lease transaction of 2015. Duffy represented Shook, Hardy & Bacon.

Miami Center is a 34-story, 803,000-square-foot, class A office tower in the heart of Miami's financial and commercial districts. Built in 1983, it is Florida's second-largest class A office building and offers a bayside location with views of Biscayne Bay, the Miami skyline, the Port of Miami and Key Biscayne.

CushWake research reveals Miami's CBD is drive strong performance of the region's overall office market. Miami has also exhibited the largest jump in Class A leasing rates among major Florida markets since the height of the last real estate cycle (2008–09), according to the Cushman & Wakefield's newly released 3Q 2015 Florida Statewide Rental Report.

"Third quarter overall vacancy was 12.6%, down 2 percentage points compared to last year," wrote senior research analyst Mirta DeCespedes in Cushman & Wakefield's 3Q 2015 Miami-Dade Office Snapshot. "Miami's CBD continued its growth pattern with new-to-market companies establishing a presence both in the U.S. as well as in Latin America. The CBD has the largest office inventory in the county and is the epicenter of the area's growth."
