Koss Design+Build designs custom homes nationwide and builds in Phoenix, Scottsdale, Paradise Valley, and surrounding Arizona communities. Its architect-led process carries projects from site studies and design through documentation and construction, with Passive House, net-zero, indoor-air, and low-emission material strategies treated as design options rather than separate add-ons.
