The House in Frogs Hollow is a country retreat located on a long slope of the Niagara Escarpment overlooking Georgian Bay in Ontario, Canada. 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. Because of the strong connection of the clients with the landscape and the nature,architect Williamson Chong constructed a house that could be totally adapted to the enviroment with both its design and materials. 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. It is a sustainable house that matches with the sporty profile of its owners who are avid cyclists and nature lovers.
