Divide a Floor
This case study involves creating distinct living units by subdividing the existing structure of the house in the vertical axis, meaning multiple units share a floor plate. Interior walls are added to create the necessary rooms within each unit and demising walls are added between units to create necessary fire separations. The project introduces new kitchens and bathrooms for each unit. Major considerations include plumbing, fire separation, and unit access.

Cost Considerations
Whenever you are deciding what type of unit to add, it is important to understand what the major cost considerations are. For a basement unit, these are:
- Underpinning
- Unit Access
- Fire and Sound Separation
- Adding Plumbing (trenching new lines is expensive!)
