Though he's mostly into Swedish pine and plywood lately, in the mid-to-late 2000's, Stockholm architect Daniel Franzen definitely had a laser-cut steel phase. One result is this awesome steel dollhouse inspired by the barn house he designed for Swedish house manufacturer Arvesund.
It's an edition of 100, and comes with magnet paper wallpaper, as well as digital templates for printing more. I wonder if you could use dry erase markers on it? Would that be cool, or a crumby, dusty disaster waiting to happen?
