More than a century ago, the Baltimore waterfront was a working harbor. After a massive 1970s redevelopment that turned the area into the centerpiece of Baltimore’s tourism industry, the American Institute of Architects called it “one of the supreme achievements of large-scale urban design and development in U.S. history.” Yet it became insolvent in 2019. Key lessons learned here can prevent this cycle from repeating as we envision what the next 100 years might hold for the center of Charm City.

Shenzhen’s Nantou Ancient City project represents a groundbreaking approach to revitalizing China’s historic urban villages in a way that preserves their cultural heritage and community fabric. After China’s government designated Shenzhen as a Special Economic Zone in 1980, the city’s more than 400 urban villages grew rapidly to provide informal housing for an influx of migrant workers. The result: high-density residential areas that maximized rental income but often compromised on fire safety and hygiene standards.

In the Belgian municipality of Edegem, just a 20-minute bike ride from Antwerp’s city center, a brownfield site that once stored camera film has become a biodiverse, sustainable mixed-use residential and commercial neighborhood.

Experts from Hines, JBG Smith, and Gensler anchored a McKinsey & Company panel, Reimagining mixed-use districts: strategies for new developments in an ever-changing world, at the 2024 ULI Fall Meeting last month. Panelists explored innovative ideas and case studies to illustrate how to make complex mixed-use projects work in today’s market.

One of New York City’s busiest corridors is set for one of its biggest transformations in years. The area around Manhattan’s Penn Station has long been considered a sore spot for the city, as top-tier retail stores moved to more flourishing areas and local buildings became outdated. But now, with a billion-dollar plan by a New York state agency underway to revitalize public transit infrastructure in and around Penn Station, there is serious momentum for the Midtown neighborhood, which has stalled in growth as surrounding neighborhoods have evolved.

As the recent cultural and real estate realignment called “The Great Mall Sorting” continues, A-plus malls are thriving, while the B and C properties are gradually being repurposed, reused, and completely rethought, according to architect Sean Slater, senior principal at the architectural firm RDC in San Diego.

As the world’s population continues to grow, there will be a need for increased urbanization to accommodate more people. The question is how and when should urban planners decide to regenerate, when to expand and when to create new cities, for sustainable growth and development of future cities, since each approach comes with its benefits and its drawbacks.

Providing end-users with a choice that originates from a binary view—either indoor or outdoor—is no longer enough.

Strict one-use-per-parcel zoning rules have long limited the growth of mixed-use projects in Spain, but the builders of a new office, residential, and commercial project in Madrid hope their example will pave the way for other integrated projects.

Shopping malls, the once-bustling hubs of commerce and community, are now facing an uncertain future in light of relentless urbanization and population growth. But as the city evolves, so too must these giants. At the 2023 ULI Spring Meeting in Toronto, industry leaders tackled this very question in the panel titled “Reimagining the Mall: The Final Urban Frontier.”
