-Concept:
  Constructing walls with a single layer of material (brick, block, or panel) at a thickness of 10-15 cm, ideal for non-load-bearing partitions and lightweight structures.  

- Applications:
  - Dividing rooms, kitchens, bathrooms.  
  - Reducing structural weight and saving space/costs.  

-Common Materials:
  Bricks, cement/foam blocks, drywall.  

Key Takeaway:
Single-layer walls are ideal for dividing internal spaces and cutting costs, but due to structural limitations, they should only be used for non-load-bearing purposes.
