relation to the landscape, a full embrace of environmental concepts by the architectural profession was many decades away. As built originally, the Six Moon Hill houses had some limitations in a New England climate. The large walls of glass that made such a visual impact were inefficient in terms of energy use. In the twenty-first century, among the first undertakings for those purchasing homes from early owners has been to replace the ubiquitous single-pane glass and uninsulated metal window frames. Similarly, the flat roofs that are typical of mid-century modern houses can be seen to be a disadvantage in a climate that routinely experiences large accumulations of snow, although this was somewhat mitigated by the introduction of new roofing materials. A continuing interest in the relationship between buildings and the environment was displayed in later years by Sarah P. Harkness when she co-authored a study on the topic of sustainable design. In a later interview, she continued to emphasize that architects needed to consider the whole environment as opposed to trying to design individual "star" buildings. Community and family life Although much current interest focuses on Six Moon Hill's mid-century modern architecture, TAC's greatest innovation there may have been how they reimagined neighborhoods and housing plans to better support child-rearing. The presence of two women who were also mothers among the founding partners of TAC (Jean B. Fletcher and Sarah P. Harkness) undoubtedly affected TAC's consideration of how design can improve family life. Unlike the Gropius House which features a separate kitchen intended to be staffed by a cook, Six Moon Hill houses were designed to function without servants and often featured kitchens which opened directly onto living areas, simplifying supervision of children. TAC's philosophy affected not only the design of individual houses but also the neighborhood layout, which included a large area of common land and later a swimming pool. These shared resources were, and continue to be, popular gathering places for children and adults. Early visitors noted the informal, supportive atmosphere of the neighborhood, and the fact that children were as likely to be found in someone else’s house as their own. Although they did not use concepts of Feminism to describe how they lived, TAC partners modeled a way of life that diverged from prevailing norms in post-World War II America, including subtly different gender roles.
