A family with multi-generational ties to a small pristine lake in Adirondack Park asked us to propose a modest house for their lakefront lot. The house would be for their retirement, and would replace the existing 1940's summer cottage with a new year-round structure. Strict code limitations regarding square footage and set-backs, along with functional and accessibility requirements from the clients, drove the footprint of the house: long and narrow, modest in height, open plan on one floor with an attached garage. A pair of guest rooms below take advantage of the sloping site, and an accessible flat roof accommodates a deck for sunbathing. The house is a simple, vertically clad cedar box that will turn silver within a few seasons. The lake side of the house is composed of a folding glass wall that opens completely, framing an expansive view of the lake and mountains beyond.
