Malcolm Wells was an architect from New Jersey who moved to Cape Cod. In 1971, he set 15 goals for his work focused on environmental sustainability and human and wildlife habitat. After realizing that his designs like a pavilion for the World's Fair would be torn down after only a few years, he developed the theory of "gentle architecture". His gentle architecture designs were partially buried underground or had features like earth roofs to blend with the natural landscape. Wells designed his own underground home and art gallery with earth roofs. He advocated for more sustainable architecture that preserved land and had a gentler footprint through his teaching and three books on the topic.
