House Customization is a new feature in Animal Crossing: New Leaf. Through the Nook's Homes shop, the player can purchase exterior modifications for their home. This includes fences, paving, mailboxes, doors, and roofing, most of which belong to a particular theme (outlined below). Like with other shops, the "stock" of what is available at the store changes daily. Players cannot purchase exterior modifications while they are having rooms expanded or added.
