GRT Architects recently completed a Dutchess County getaway for New Yorkers contemplating a move upstate. The 800-square-foot home—featured online a few months back—radiates on a three-axis pinwheel floorplate and incorporates a number of eco-friendly elements.

Joining this pared-back retreat is a new 440-square-foot painter’s studio. Set apart from the main cottage on the 24-acre lakefront property, this latest edition champions the same sober yet impactful palette of materials.

The blackened cedar and copper-clad box packs a punch with a super-efficient kitchen-bathroom-shower unit, a small motorcycle garage, and a sun-drenched studio. With expansive views of the lake a few yards aways, this main rooms doubles as a guest bedroom. Anchored in plywood-framing, recycled cellulose boards provide good insulation and can be used to pin-up artworks. The compact shower unit is covered in a unique blue and white tile mosiac concieved by artists Luke Murphy and Yael Meridan Schori. A central skylight floods-in additional natural light.
