I'm planning on converting a 21x21 garage to a living room in the next couple years. I've got pretty much everything figured out I believe, and it seems a bit simpler than the bonus room conversion I finished earlier this year.

Has anyone done this, and have any tips / unexpected things I might encounter?

Thing's Ive investigated / confirmed / planned so far:

• Leveling the graded concrete floor
• Filling the entrance hole with an exterior rated wall + windows
• Insulating the preexisting exterior wall segments
• HVAC connection
• Additional electrical outlets
• Framing an entrance to the space in the adjacent load bearing wall
