Additional Notes Studio 804, Inc., is an independent not-for-profit 501(c)3 corporation, affiliated with the University of Kansas. Participants are graduate students of the School of Architecture, Design and Planning under the instruction of JL Constant Distinguished Professor Dan Rockhill. Studio 804 projects adhere to standards of the highest quality, both in design and fabrication, and address important issues of environmental sustainability, energy efficiency and accessibility. The structures are innovative architectural designs that address important issues pertinent to the professional field. For the last seventeen years, Studio 804 has pioneered new technologies and advanced construction techniques in the areas of sustainable design and innovative methods of construction. As a not-for-profit organization, we are committed to promoting high quality architecture and serving the needs of the state, Lawrence and the Kansas City Metropolitan Area. Since its inception, Studio 804 has become more ambitious in its pursuits and increasingly sophisticated in its methods. Through the efforts of our students we have been successful in gaining support from industry leaders who see us as an opportunity to showcase their new and often innovative products. All aspects of the building process are carried out by the students over the course of a single semester. Students are involved in everything from initial design to finished construction and documentation. Studio 804�s attention to detail and pursuit of building innovation and energy efficiency has led to a significant amount of national and international exposure and interest in the form of numerous accolades and publications. With five LEED Platinum projects completed to date (three certified, two pending), we are proud to be leaders in sustainability among professionals in the region and intend to continue in that effort for the immediate future.
