The requisite bulk of a large program is set into the sloping landscape, providing a play of levels and terraces that diminish the built presence and enhance the experience of the lakeside site.

Full-height glass panels slide back in bedrooms to become sleeping porches, while sunken courtyards become outdoor living rooms.
