A Trenton Transformation: Princeton Hydro Headquarters

Located in Trenton’s historic Roebling Complex, Roebling 110 represents the second phase of a multi-phase redevelopment project that is transforming five vacant industrial buildings close to downtown Trenton into a vibrant, mixed-use community. Prior to this project by Hx2 Development, LLC, which was designed by the architectural firm Clarke Caton Hintz, Building 110 had been in extremely poor condition, with portions of the roof structure collapsing all the way to the basement. It was originally constructed in 1908 as the John A. Roebling’s Sons Company’s Carpentry Shop.

The 9,000-square-foot Roebling 110 building renovation cost $4.5 million and employed approximately 100 construction workers; the second floor is now the new headquarters for integrated ecological and engineering consulting firm Princeton Hydro. It includes state-of-the-art offices, and collaboration and conference rooms for its more than 30 full-time, onsite employees (50 employees overall). It also features incredible natural lighting and ventilation, and additionally showcases a tangible manifestation of the firm’s deep commitment to sustainability and smart growth.

The site’s proximity to a light rail station and to the Trenton Transit Center means employees can use mass transit to get to work. Perhaps more importantly, the firm’s clients, who may be located along Amtrak’s Northeast Corridor line, can easily connect with the firm.

This project has transformed a long vacant eyesore into an extraordinary headquarters for Princeton Hydro, bringing vitality to the site and spurring other firms to make similar moves.
