How to Design with Red

A dim Toronto Tudor gets an airy new look. The home’s second-story hallway, which serves as an open office and library, was suffering from a severe lack of light. Lifting up one side of the old pitched roof made room for a linear skylight, which faces south to allow in as many rays as possible, and the modification transformed the top floor into a loftlike double-height space. Inexpensive detailing then added texture and scale: Simple plywood panels attached to cold-rolled-steel frames serve as guards along the stairs.
