Throughout a century of practice, H2L2 Architects/Planners has maintained a position at the forefront of design and technology by anticipating change and responding with innovative and cutting edge solutions. Sustainable design has always been a cornerstone of H2L2's practice, beginning with our founder, the renowned architect Paul Philippe Cret, who, in the early part of the twentieth century, designed a groundbreaking rain water collection and irrigation system as part of the World War I Chateau Thierry American Monument. In the latter half of the same century, H2L2 won the First Recipient Energy Conservation Award for our innovative design of the Children's Hospital of Philadelphia.

H2L2's expertise allows us to mentor clients, fostering their understanding about what sustainable concepts truly mean in terms of end results on investment. We believe in creating and building socially vibrant, ecologically restorative, and economically sound communities. Our portfolio includes a distinct collection of beautifully designed live, work, play and rest spaces that truly enhance the health and well being of both people and ecosystems, now and in the future.

H2L2 has built a staff of LEED accredited professionals and, as a public promise, we intend to have 100% of our design staff LEED accredited by 2010. In doing so, we hope to foster the kind of industry-wide commitment to sustainability that will change the way the built environment interfaces with and supports the world around us.
