Ideas for converting an unfinished space

Ideas for converting an unfinished space

This garage conversion case study involves creating a distinct living unit by adding to the existing structure of the garage to create a self-sufficient living unit. Existing walls are insulated from the inside and fire separated from the rest of the house. The project introduces a new kitchen and bathroom with very few additional partition walls. Plumbing is a major consideration as the existing garage has no connections for the required kitchen and bathroom.

Cost Considerations

*This sample design might cost somewhere in the range of $195,000 - $367,000

Whenever you are deciding what type of unit to add, it is important to understand what are the major cost considerations. For a basement unit these are:

  • Retrofitting insulation
  • New bathroom
  • New kitchen
  • Connections to main home (plumbing/electrical/communications)
  • New openings (windows/doors)
