This simple painting studio includes living quarters for an artist and frequent weekend guests. A familiar vocabulary of traditional forms and materials slants gently toward the sun and views up the Slocum River. The cantilevered roof and upper storey shelter the glass from summer sun. The concrete floor absorbs energy from low winter sun during the daytime to release it at night. Walls of exposed studs inside are wrapped and sealed with a continuous plane of insulation applied outside the structural sheathing.
