I'm not going to get into everything my house would be, but I absolutely love boutique-styled rooms. Small, themed, with very cool lighting. For example, I would have a few pretty small reading rooms. Maybe each would have a reading theme, a few themes could be "France," "How to's," a samplings of encyclopedias from the world, etc. Thus, the entire reading selection for each little room would be focused on each individual subject. There would be nice, overstuffed chairs for sit and read with thick, warm blankets. The rugs would be richly-dyed and antique. There would be a lot of hardwood and instead of large area lights, there would be many, smaller, hidden lights. Such as built-in lights in the bookshelves, smaller tiffany-style lamps, etc
