A major new residential tower is rising along the Jersey City waterfront as construction begins on Harborside 4, an 800-unit mixed-use development that will add significant housing density to one of the fastest-growing urban markets in the United States.
The project, located at 20 Columbus Drive in downtown Jersey City, is being developed through a joint venture between Related Companies, Panepinto Properties, and Abu Dhabi–based Modon Holding.
Once completed, the tower will deliver approximately 800 residential units, including a mix of rental apartments and condominiums, along with ground-floor retail and public space.
A New High-Rise on the Waterfront
Harborside 4 is planned as a 55-story residential skyscraper designed by Handel Architects, known for large-scale urban residential and mixed-use projects.
The development will include:
- 800 residential units (approximately 600 rentals and 200 condos)
- 12,000 square feet of retail space at street level
- a public plaza and landscaped open space integrated into the site
- a full amenity package including a fitness center, lounges, and rooftop pool
The tower’s design features an L-shaped massing with rounded glass corners and a multi-story podium, helping activate the surrounding streetscape in the Exchange Place district.
The site — previously a surface parking lot — is bounded by Columbus Drive, Hudson Street, and Greene Street, placing it within walking distance of PATH service and the Hudson River waterfront.
Backed by Global Capital
The project reflects the continued influx of international capital into the Jersey City market.
In late 2025, Modon Holding announced it would take a majority equity stake in the project as part of a joint venture with Related and Panepinto.
The partnership marks a significant cross-border investment, with global investors targeting high-growth U.S. residential markets tied to major metropolitan centers like New York City.
Construction is expected to begin in 2026, with completion projected around 2029.
Jersey City’s Waterfront Development Boom
Harborside 4 is part of a broader wave of high-density residential development transforming Jersey City’s waterfront.
Over the past decade, the Exchange Place and Newport districts have evolved into major residential hubs, driven by:
- direct PATH access to Manhattan
- lower relative housing costs compared to NYC
- large-scale redevelopment of former industrial and commercial sites
Projects like Harborside 4 continue the transition of the Harborside complex — historically an office and warehouse district — into a mixed-use residential neighborhood.
The development also follows several recent large-scale projects in the area, reinforcing Jersey City’s position as one of the most active construction markets in the Northeast.
Final Thoughts
The groundbreaking of Harborside 4 highlights the continued momentum behind Jersey City’s transformation into a high-density residential extension of the New York City metro area.
With 800 new units, global investment backing, and a prime waterfront location, the project represents one of the most significant residential developments currently underway in the region.
As development activity continues across the waterfront, projects like Harborside 4 are helping redefine Jersey City as a major urban center in its own right — not just an alternative to Manhattan, but a destination for large-scale investment and long-term growth.
