Accessory dwelling units
An ADU is a small building on a constrained site next to somebody's house. Speed, quiet erection and a shell that needs no crane all matter more than they would on an open lot.
The site is usually a back garden with limited access, so a panel that two people can place beats one that needs a crane. Construction happens next to people who live there, which puts a premium on a short, tidy build.
ADUs are also small enough that the envelope dominates the energy use, and are frequently required to meet a high efficiency standard as a condition of the zoning that permits them.
Guardian names ADUs as a distinct residential market. The Product Performance Analysis published on this site is DEMO Architecture's all-electric ADU proposal for the town of Kingston, which Guardian priced.
