Duplex houses can be next to each other or stacked.
Duplex houses can be next to each other or stacked. Within these two main categories, there are many different types possible, such as single-story or multi-story, which can be divided into ranch and mansion styles. A duplex home may have two adjoining garages in the center of the project or have them at one end. Of course, some duplexes do not include garages in the project, but only have entrance doors. Some duplexes feature front doors in the middle of the house plan with a large covered roof above them.
Mansion-style homes can be duplexes.
Centered entrances or garages can be horizontally aligned with the rest of the project, or the main living units can be placed behind them. Typically, in side-by-side duplex homes, entryways or garages form a shared wall between the two separate living units. This type of duplex layout can reduce the amount of noise between units, since the walls or floors of the living room are not shared. A duplex dwelling plan might focus on providing the least amount of transferable noise between the two separate dwelling units, or it might have a more basic design of one completely shared wall or floor.
A tiled duplex with entrances that are also part of the main building and do not face rear or front will have a shared wall that can transfer noise quite easily. If these side-by-side duplexes are of the multi-story type, the shared wall may divide bedrooms, bathrooms, or other main living areas. Also, in stacked duplexes, a shared horizontal area, which is the ceiling of the lower unit and the floor of the upper unit, can more easily transmit sound through the main spaces.
Mansion or block duplexes can be side by side or stacked on the floor plan. Many of them are both, as they have multiple floors and adjoining entrances. Of all the different possible layouts for duplex homes, this type is often the hardest to tell is a multi-family dwelling. Just looking at the two separate entrance doors under the single roof at the front of the building reveals the “secret”.
Ranch-style duplexes tend to be lighter in their double-dwelling format. These single-story tiled duplexes typically have a reverse plan layout that is quite obvious from the outside. Entryways may have separate covered porches or pathways to each front door.
