Joe, Wanted you to know how thrilled I am with our collaboration on my home renovation. So many aspects of this transformation are remarkable, starting with the vision, design and collaboration and skill of many. The modular experience has been everything you said it would be. So many of the trades man and woman have commented on and been impressed with the quality, detail and how it came together. Thank you for your oversight! Regards, Andrea Gogolos

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.
