Friday has been retained by the University of Pennsylvania to plan a variety of interesting improvements to the massive David Rittenhouse Laboratory Building that occupies nearly an entire city block. The University has asked Friday to prepare “interventions” around the building that would improve the public spaces and encourage more social activity in the building. The existing system of corridors and stairs are difficult for new visitors to navigate. Friday has developed concepts for new large scale graphic signage throughout the building as well as micro-lounges carved from under-used classroom space. The signage employs patterns derived from the architecture of the building and abstractions symbolic of the departments housed within.
