The University of Pennsylvania was interested in designing and installing a classroom amongst the trees within their arboretum. The catch with the project was that none of the surrounding area could be damaged during the installation process, including the surrounding ground. After several companies said that they couldn't supply them with what they wanted, Custom Fabrication Inc. came in and said YES! The custom design on this architectural structure is extremely pleasant to look at. Once the successful installation was complete, professors would bring students into the "treehouse classroom" for educational sessions on topics such as foliage.
