ADUs (Accessory Dwelling Unit) are becoming more prevalent in Eugene as a means to increase density where zoning allows. As my final advanced technology requirement, I took a course entitled Residential Construction with professor Rob Thallon at UO. My term project consisted of a quick exercise to design a potential ADU for the house I was renting at the time in South Eugene. In time with various lectures covering utilities, foundations, framing, enclosure details, and ADA requirements, the design was shaped and troubleshot.
The simple rain screen system as well as the idea to spec denim batt insulation and galvalume flashing was inspired by my hands-on experience with the walls of CASL house.
