A small German township, a tight building envelope
Darmstadt's population sits around 1,400, and the town has stayed small and tight-knit since its 1822 founding as a German Township community, incorporating on its own only in 1973. Small, older communities like this often have homes built close together with construction details typical of their era rather than modern moisture-management standards.
Township-era construction and moisture-source correction
A building stock this compact, spanning 19th-century township-era construction through post-1973 homes, benefits from moisture-source correction that treats each property's construction era on its own terms rather than assuming one standard across a town this size.
