A granny flat is a small, self-contained living space typically located on the same property as a larger home. These units are often designed for elderly family members, hence the name, but can also serve as guest accommodations or rental units. They usually include a bedroom, bathroom, and kitchenette. Granny flats can be built as separate structures or converted from existing spaces like garages or basements. They provide a way to maintain family connections while offering privacy and independence. Many regions have specific regulations regarding their construction and use, so it's important to check local laws before building one.
