Using the same proportions and materials, the workshop flows in continuity with the main house while its partial burying hides the volume and preserves the leafy environment.
I am a sucker for plywood, It has a real warmth that you just don't get out of paint and drywall. If it ever floods down there it will suffer a lot less damage than other materials. Here they have light, air, lots of room and it doesn't take up the whole yard. Nice. More at l'escaute, cooperative of Architects.
