A townhouse is a type of residential building that shares one or more walls with adjacent properties. Typically, townhouses are multi-story structures, offering multiple levels of living space. They are often part of a larger community or development, which may include shared amenities like parks or pools. Townhouses are popular in urban areas where space is limited, providing a balance between single-family homes and apartments. They usually have their own entrances and may feature small yards or patios. This style of living allows for a sense of community while still offering privacy to residents.
