John Connell founded the Yestermorrow Design/Build School in 1980 and the Yestermorrow Building Group Inc. (later to become 2morrow Studio in 1982.) He taught at Yale's school of architecture for five years after which he authored the book Homing Instinct: Using Your Lifestyle to Design & Build Your Own Home, McGraw Hill, 2000. Besides teaching he is currently designing green homes that tell "stories", design/building treehouses for handicapped children, and animating short films. 2morrow Studio puts into actual practice the design/build philosophy taught at the Yestermorrow School. A small design/build firm in Vermont, 2morrow Studio works with residential and small commercial clientele interested in integrated energy-efficient architecture using the latest green and sustainable methodologies. Besides architectural design, Connell is an experienced team builder, group facilitator and educational program designer. The Yestermorrow School teaches people how to plan, design, build or renovate their own homes. It is staffed by over 40 architects, builders and artisans from all over the United States who believe that the way to improve the built and natural environments is to re-involve people in vernacular architecture.
