Organize a series of rooms. "When we refurbished this midcentury modern brick house, we used cabinets instead of traditional walls to organize the back entry, mudroom, kitchen, family dining booth, kitchen office/work areas — two of them — and the transition to the living and dining area," says Tom Hurt of Hurt Partners Architects. "The bookcase is made of a clear finished maple," he points out, "and parts of this cabinet system have solid panels, other parts obscured glass, and towards the rear [in this photo] is a large pin board for the kids' projects, family photos and such." The ceiling material is custom-milled clear fir, and the floor is honed Italian limestone.
