Professional Plaza Tower

Introduction: History and Significance

The Professional Plaza Tower, affectionately known as "The Plaza" or the "Hammer and Nail Building," stands as a testament to Detroit’s mid-20th-century urban renewal, architectural innovation, and enduring cultural heritage. Located at 3800 Woodward Avenue in Midtown, Detroit, this 12-story International Style structure was completed in 1966 as part of Detroit’s 1958 Medical Center urban renewal initiative. Originally developed to support the Detroit Medical Center and nearby hospitals, the building quickly became a hub for medical professionals, research institutions, and healthcare organizations, highlighting Detroit’s leadership in medical innovation (Historic Detroit).

Designed by Gerald Crane and Norbert Gorwic, the tower exemplifies Mid-Century Modern and International Style architecture, featuring a glass-aluminum curtain wall façade, clean lines, and prominent concrete columns. Its signature neon “Hammer and Nail” sign—added in the 1980s—became a beloved cultural marker, reflecting Detroit’s labor and industrial legacy and the building’s association with the Michigan Regional Council of Carpenters and Millwrights (Curbed Detroit).

Over time, the Professional Plaza Tower has mirrored Detroit’s journey through periods of growth, decline, and revitalization. After facing near-vacancy and threats of demolition in the 2010s, the building was preserved and adaptively reused. It now operates as a Marriott extended-stay facility with 92 units, serving medical visitors and professionals and contributing to Midtown’s ongoing renaissance (Hotel Management Network; Preservation Detroit).

Today, the tower offers architectural interest, historic context, and proximity to Detroit’s top cultural institutions, such as the Detroit Institute of Arts and Wayne State University. This guide covers visiting hours, access, tours, travel tips, and FAQs to help you make the most of your visit (Detroit Historical Society).

Urban Renewal and Medical Community

The Professional Plaza Tower was a cornerstone of Detroit’s Medical Center urban renewal plan, intended to anchor a state-of-the-art medical district. Its development, however, came at the expense of a vibrant pre-existing neighborhood—a reminder of the complexities of mid-century urban transformation (Historic Detroit).

Design and Iconic Features

Architects Gerald Crane and Norbert Gorwic designed the tower in the International Style, emphasizing function and modern materials. Its curtain wall of glass and aluminum, prominent concrete columns, and minimalist geometry are classic mid-century modern elements. The building’s iconic “Hammer and Nail” neon sign, installed in the 1980s, became an enduring symbol of Detroit’s skilled trades and labor history (Curbed Detroit).

Evolution, Decline, and Rebirth

Initially filled with medical and dental offices, the tower’s occupancy waned in the late 1990s as healthcare providers moved elsewhere. By 2014, it was nearly vacant and at risk of demolition (Detroit News). Preservationists intervened, and by 2017 the building was restored and repurposed as contemporary apartments and retail space. In December 2023, it was converted into a Marriott extended-stay hotel with 92 units, tailored for medical and business visitors (Hotel Management Network).

Cultural and Social Significance

Beyond its architecture, the Professional Plaza Tower is recognized as a site of significance for Detroit’s LGBTQ+ community and as a symbol of the city’s resilience and commitment to preservation (Preservation Detroit; Outlier Media).
