Color and material cues help Matthew navigate the house. Reclaimed wood from a local barn marks the dining room, which also features a table from BoConcept, a Graypants pendant lamp, and molded-fiberglass chairs by Charles and Ray Eames. In the living room, the color palette of the Design Within Reach sofa and built-in bookshelves was inspired by maple trees in fall. "That’s really what universal design is about: making it as stylish as anything you’d put in anyone else’s house, but having the ability for it to be accessible," says Coplen.
