PBS Modular teams up with Orens Brothers – Diamond Green Project

PBS Modular teams up with Orens Brothers Real Estate to build 116 modules for the Diamond Green Project Professional Building Systems Inc. recently had the opportunity to help in the revitalization efforts of the Diamond Green Project in Philadelphia, PA. Consisting of 116 modules, the corner of 10th and Diamond Streets is now home to a five-story structure with retail and restaurants on the first floor and 350 beds in 92 furnished units on the floors above. Utilizing modular construction allowed Orens Brother Real Estate to vastly increase their ability to construct this large scale project in a much shorter amount of time than the traditional means of construction.

Our Offices

Professional Building Systems, Inc. was founded in April of 2000 and has grown to become one of the largest modular manufacturers on the east coast. PBS produces over 1,000 living units per year, including ranch, cape, and two-story homes as well as apartments, dormitories, schools, and other light commercial structures.
