This playful Uptown cottage, with its secret hiding spots and colorful walls, feels like the house a nine-year-old boy would have designed if he were in a Blank Check-type situation. Originally renovated by author Lloyd Vogt, the living area here is big and open, but there's a giant, non-functioning fireplace smack-dab in the middle. A charming detail to incorporate, or just clunky? You can peek out onto the living room from the loft upstairs. There's also a loft bed in one of the bedrooms, which has a lot of high-up storage. Potential homeowners: must love ladders! The asking price for three-bedroom, two-bathroom? $550,000.
