Houses Treyz Residence A historic eighteenth century farmhouse has been more than doubled in size to create a garden wing. The new wing provides modern spaces that flow into each other and open out to the garden, and include kitchen, breakfast room, family room, home office, garden room, wine cellar and master bedroom suite. In exterior appearance, the house continues an aesthetic derived from agricultural and vernacular sources, but rendered in an abstracted way.     location: Chappaqua, New York services provided: Architecture and interiors
