Sometimes you can't avoid bringing work home with you, but with an elegant home office like this one, you might not mind the daily grind. These interesting built-in home office ideas by Paul Raff Studio based in Toronto, Ontario, Canada make great use of often-overlooked space, putting the areas under the staircase and on the wall to work. Tucked under the stairs, a desk offers intimacy and privacy in this vast, triple-height open-concept living space. A system of wall cabinets offers plenty of storage space for files, books and computer equipment, all hidden neatly away behind anthracite-painted cabinet doors. Behind the doors you'll also find a stockpile of firewood to feed the built-in high-efficiency wood-burning stove. Oh, and did we mention there's also an integrated cocktail bar?
