Harborside 4 Breaks Ground in Jersey City

Key Points

• Related Companies, Modon Holding, and Panepinto Properties have started construction on Harborside 4
• The 55-story tower will deliver 800 residential units and ground-floor retail
• Completion is targeted for early 2029

Construction is underway on Harborside 4, a new 55-story residential tower rising at 20 Columbus Drive in downtown Jersey City. The project adds another major high-density development to the city’s fast-growing waterfront corridor, just steps from regional transit. The site is bounded by Christopher Columbus Drive, Greene Street, Hudson Street, and Pearl Street, placing it within walking distance of Exchange Place and direct PATH service to Lower Manhattan.

Project Overview

Harborside 4 will deliver 800 residences, split between 600 rental apartments and 200 condominiums, along with 12,000 square feet of retail space across three storefronts. Units will range from studios to two-bedroom layouts. Residential amenities will include a health club, indoor and outdoor lounges, concierge services, and a rooftop swimming pool, positioning the tower for both renters and condo buyers seeking full-service living near transit.

Design and Public Realm

The tower is designed by Handel Architects and features a multi-story podium with a sculpted notch at the southeast corner. Above, the building rises in an L-shaped form with rounded corners and a stepped massing that differentiates the eastern and western volumes.

Renderings show a copper-toned façade organized in a triple-height grid framing floor-to-ceiling windows, including curved glass at the corners. A landscaped public plaza and tree-lined sidewalks are planned around the base, reinforcing the site’s pedestrian connection to the waterfront.

Transit-Oriented Location

Harborside 4 sits a short walk from the Exchange Place PATH station, providing one-seat access to the World Trade Center. The location continues Jersey City’s pattern of dense, transit-oriented residential development that has attracted both institutional capital and Manhattan commuters priced out of New York City.

A Long-Term Bet on Jersey City

The joint venture reflects sustained confidence in Jersey City’s residential fundamentals, particularly along the waterfront, where new supply continues to lease and sell against strong demand. The mix of rentals and for-sale units gives the project flexibility across market cycles.

Bottom Line

Harborside 4 adds another major tower to Jersey City’s skyline, reinforcing the city’s role as a high-density, transit-driven alternative to Manhattan. With construction now underway and delivery set for 2029, the project underscores continued momentum in one of the region’s most active residential markets.
