Two-story duplex is a type of housing that has two floors, usually with two separate living units. Each unit typically has its own entrance and its own kitchen, bathroom, and bedrooms. The main difference between a duplex and a single-family home is that the two units are connected either vertically or horizontally. This type of housing can be ideal for families who want to live close together but still maintain their own separate living space. It can also be great for those looking to maximize rental income from one property. Additionally, it provides more privacy than other multi-family dwellings such as apartment buildings or townhouses.
