The property is a collection of eroded clay hills and protected watershed zones blanketed with a dense field of hawthorn and native grasses. It is not picturesque, but tough and rather impenetrable. The house’s connection to the land is reinforced not only in its architectural form, but also in its environmental footprint. The house is heated with radiant floor loops that supplement the passive winter heat gain from south facing windows. In addition, there is no mechanical cooling. Instead, the stair tower and operable windows facilitate passive ventilation that draw cool air through the house from shaded exterior areas. Natural materials and pigments were used throughout and a small square footage was maintained to further reduce construction costs and keep future energy consumption to a minimum.
