OJS Doghouse 

Architect: William Pedersen

"Set on an urban terrace, in a backyard, or even in a living room, the One Jackson Square Dog House offers a fresh take on canine quarters.  Designed for the city dog, the country dog, and the spoiled dog, the organic form cradles the curled up canine in slumber, while the grassy-eco-friendly-rooftop fulfills every dog's dream of a perch with a panoramic view." - KPF
The One Jackson Square Doghouse designed by Trent Tesch and Bill Pedersen of KPF was jointly sponsored by Hines, KPF and Situ Fabrication for a charity event held by The Animal Medical Center.  The doubly curved form is made of 57 layers of 1/2" thick baltic birch plywood cut into 1" wide pieces.  The pieces are then laminated together with the aid of alignment dowels, resulting in a rigid plywood shell.  Situ Fabrication worked from a Rhino surface model provided by KPF and developed a Grasshopper definition to facilitate fabrication.  The definition was used to slice the model into horizontal layers as well as to create staggered vertical seams within each layer to produce a more efficient nesting layout.  The GH definition also generated positions for the alignment dowels, numbered each piece, and laid them out onto 4' x 8' cutsheets.  The cutsheets were then CNC routed, assembled and finished within a week.
