Changed since the photo was taken. Got it all insulated except for one wall before winter hit. 1/8" x 60" x 120" aluminum sheets on the ceiling , 5/8" plywood on the walls.. I live on the mezzanine left of the suspended cab. Glass garage door leads to a small deck in the future. Radiant floor on the mezzanine and in the garage floor. 760sqft with average 16ft ceiling. Not finished but it's all paid for.
