Plan for windows. The last thing you want in a room where you’ll be spending hours upon hours is the absence of ample light. Natural light in particular can have a direct impact on mood and motivation. “For a successful conversion of an attic into a home office, the room should allow for a well-proportioned window that can be integrated into the overall architecture of the house, either in the form of a dormer — if the roof and city codes allow for that — a gable window or a nice operable skylight,” says Barnett. Think bright with white. Continue to brighten by choosing white or a light neutral for the walls and furnishings. “Again, you’re spending great chunks of time in here,” says Barnett. “Transforming it into a nice and comfortable area will instantly make it more habitable.”
