Design Boom has a profile of Wells.
"Wells devoted most of his life to finding ways of building without destroying the land, making it his credo to 'leave the land no worse than you found it.' having never been formally trained or holding any sort of degree, at the age of 60 he was asked to teach an environmental design course at Harvard. Wells tried through writing, illustrations, lectures and personal examples, devoting his life
to convincing his fellow humans that 'a building should consume its own waste, maintain itself, match nature's pace, provide wildlife habitat, moderate climate and weather and be beautiful.'"
