About GonSosa Development

Since 2001, GonSosa has built an extensive portfolio of multi-million dollar development and construction projects throughout New Jersey and the greater New York/Tri-State Area. These successful projects have earned us an outstanding reputation for excellence among industry and community leaders. Our portfolio includes as many multi-family units in New Jersey’s urban towns as commercial developments in bustling cities, making us one of the most versatile general contractors in the industry. We exceed our client’s expectations in every retail, commercial, residential and redevelopment project we undertake because we have the expertise and insight to help local communities realize their full potential.

Our Philosophy

As a community-oriented business, we are deeply committed to making a positive impact on every neighborhood in which we have the privilege to work. Our dedication to efficiently delivering only the highest-quality products and building responsibly within communities makes us a trusted builder of many popular franchises. We’ll exercise the same care and concern when doing construction on your street as if we were building in our own backyard; as such, we’ll ensure our buildings and the surrounding landscape enhance your neighborhood. We see every building contract as a mission to leave a positive lasting impression on a community, and we look forward to becoming part of yours.

In The Community

By volunteering with local service organizations and coaching youth sports teams, members of the GonSosa team give back to the communities that have given us so much.
