Mercer Island, Washington
Lake Washington Residence
This 4000 s.f. residence and carport is located on a steep wooded
site on Lake Washington. Entered from above via a bridge, this
residence transitions between a steep forest and open sweeping
views of Lake Washington. The bridge lands on the 3rd floor covered
roof terrace, which offers protection and an upper level deck.
A central steel and concrete stair descends through the house
to the living area on the ground floor which opens to the shore.
Two large cantilevering wood framed boxes rest on a continuous
concrete wall. They contain the more private program spaces on
the second and third floor; a self contained guest house is located
on the top floor. The "boxes" are clad on all surfaces
in clear cedar siding which continues to clad the ceiling under
the boxes. The edges are trimmed in contrasting metal. The glazed
void between the boxes is occupied by the main stairway. As one
descends down the stairs, the view alternates between open water
and hill side. The house is naturally ventilated; the central
stair acts as a "stack" to pull air through the house.
The primary materials for this house are wood framing, exposed
concrete and concrete floors, red cedar siding, galvanized and
black steel. The window systems are wood exterior clad in mill
finish aluminum. Cabinets are bamboo veneers on apple-ply plywood.
