Before building a duplex house, knowing what you want is best. The more specific you are with your plans, the better. Here’s what you should consider when planning a duplex.

  • The structure of the duplex— Duplexes come in all shapes and sizes, so it’s important to know what kind of duplex you want. Do you want it to be two separate units or one large unit split down the middle? Do you want a garage on each unit, or will there be one shared space for both?
  • Rooms and features — Will either unit have an office or guest room? Will they have their bathrooms? What kind of kitchen do you want? How many bedrooms does each unit need?
  • Location — Where will the duplex be located? What’s around it? What are the neighbors like?
  • Style — Do you want modern, traditional, or something else entirely? Is there any particular style of home that stands out as something you can see yourself living in long-term?


A half-plot building seems like a curious combination to some people primarily because they don’t know how big half a plot is. Also, they assume duplexes need so much space.
