West Side Square Development Fund, a four-partner team comprising Lanterra Developments, Westdale Properties, Lantree Developments and Altree Developments, announced the signing of Square Market as the first retail tenant at West Side Square, the highly anticipated mixed-use development at 1075 West Side Ave. in Jersey City’s Marion neighborhood.
This collective, inspired by Jersey City’s industrial heritage, believes it is redefining urban living and embracing the neighborhood’s past while looking toward the future.
Square Market will occupy 1,500 square feet of ground-floor retail space. Bobby Antonicello Jr. of GRID Commercial Real Estate Advisors represented both sides of the transaction.
Incorporating Square Market into the destination further strengthens the development’s positioning as a convenient hub for daily life within the fabric of the emerging Marion neighborhood. An official opening date for Square Market has not yet been announced
“Welcoming Square Market as our first retail tenant is another step toward realizing our vision of creating a vibrant neighborhood destination and we are excited to announce additional retail tenants in the months to come,” said Raphael Mandelbaum, principal at Lantree Developments.
West Side Square is scheduled to welcome its first residents in August 2026. The 477-unit community features a mix of studios, one-, two-, and three-bedroom residences, including townhome-style layouts, along with amenities such as a rooftop pool, fitness center, yoga room, pet-friendly spaces and 24-hour doorman service. Property management and leasing are overseen by Greystar, based in Charleston, S.C.
