Semi-detached Houses Offer Efficient Land Use and a Combination of Space and Affordability. They Are More Affordable Than Standalone Single-Family Homes and Offer More Space Than Apartments or Condos. With an Open Floor Layout, in Which the Common Living Areas Are Connected and Open to Each Other Rather Than Separated by Walls or Doors, the Design Offers Many Benefits, Including a Sense of Spaciousness, Improved Natural Lighting, Uninterrupted Sightlines, Flexibility, Improved Traffic Flow, a Modern Aesthetic, Enhanced Natural Ventilation, Increased Energy Efficiency, and a Greater Sense of Community.
