Basic  rules for design of  single-unit duplex house:

When designing a single-unit duplex house, there are some basic rules and considerations to keep in mind. 

Here are a few guidelines to help you with the design process:

Space Planning:

  • Divide the house into two separate living units that are mirror images of each other.
  • Ensure each unit has its own entrance and living spaces, including bedrooms, bathrooms, kitchen, and living areas.
  • Allocate space for shared utilities such as laundry rooms or storage areas.

Privacy and Noise Control:
  • Design the shared wall between the units to provide sound insulation and privacy.
  • Place bedrooms and quiet areas away from the shared wall to minimize noise transfer.
  • Consider the placement of windows and use curtains or blinds for added privacy.

Functional Layout:

  • Create a logical flow within each unit, with a clear separation of public and private spaces.
  • Optimize the use of space by considering the placement of furniture, storage, and fixtures.
  • Ensure that the layout allows for easy movement and functionality in each unit.

Natural Light and Ventilation:

  • Incorporate ample windows and openings to allow natural light into each unit.
  • Consider the orientation of the house to maximize sunlight exposure and airflow.
  • Provide windows in areas such as living rooms, kitchens, and bedrooms for natural ventilation.

Safety and Accessibility:

  • Include safety features such as smoke detectors, fire extinguishers, and emergency exits in each unit.
  • Design the house to be accessible for all occupants, including considering the needs of people with disabilities.
  • Ensure that staircases, doorways, and pathways meet accessibility standards.

Exterior Design and Aesthetics:

  • Create a cohesive and visually pleasing exterior design for the duplex house.
  • Choose materials, colors, and finishes that complement each other and the surrounding neighborhood.
  • Pay attention to landscaping and outdoor areas to enhance the overall appeal.

Building Codes and Regulations:

  • Familiarize yourself with local building codes, zoning regulations, and permit requirements.
  • Ensure that your design complies with these regulations, including setback requirements and building height restrictions.

Remember, these are general guidelines, and it's essential to consult with professionals such as architects, engineers, and contractors to ensure your design meets all the necessary requirements and regulations specific to your location.

Certainly! Here's a basic single-unit duplex house design:

Overall Structure:
  • The duplex house consists of two separate living units, each with its own entrance.
  • The units are mirror images of each other, with a shared wall in the middle.
Exterior Design:
  • The house has a symmetrical facade with a central entrance leading to a covered porch or foyer.
  • The exterior can feature a combination of materials such as brick, stone, or siding, depending on your preferences.

Floor Plan:

Ground Floor:
  • Each unit has its own separate living space, including a living room, dining area, and kitchen.
  • The kitchen can be an open-concept design or closed off from the other areas.
  • A utility room or laundry area is typically located on this floor.
  • There may be a guest bathroom near the entrance for convenience.
Second Floor:
  • Each unit has a similar layout on the second floor.
  • The upper floor typically consists of two or three bedrooms, including a master bedroom with an en-suite bathroom.
  • A shared bathroom serves the other bedrooms.
  • Each unit may also have storage space or a small study area.


  1. Parking: Provide parking space for each unit, either in a shared garage or individual driveways.
  2. Outdoor Area: You can have a backyard or a small patio area for each unit.
  3. Utilities: Each unit should have its own electrical and water meters for individual billing.
  4. Design Considerations:
  5. Privacy: Ensure that the shared wall between the units is well-insulated to minimize noise transfer.
  6. Natural Light: Incorporate ample windows and glass doors to maximize natural light in both units.
  7. Safety: Install smoke detectors and fire safety measures in each unit to ensure the safety of occupants.
  8. Accessibility: Consider designing at least one of the units to be accessible for people with disabilities if needed.
Remember, this is a basic design, and you can customize it to suit your specific needs and preferences. Working with an architect or designer can help you create a duplex house that meets all your requirements.
