This extra large garage with apartment has more than enough room to open your vehicle doors and move around comfortably inside the building.

Height CheckThe lower level has a towering 9' ceiling height. With this new two story garage we've incorporated the LVL beam construction as STANDARD to maximize the interior clear span. This has allowed us to pare down the support walls to a very skinny 1’-2’ each on garages up to 24' in length. On larger garages, you’re still guaranteed a 24' clear center span.


As with all our 2-story garages, the steps are full-sized and securely placed. No ladders or pull-down stairs here. The staircase includes a rock-solid wooden handrail with wooden balusters. The handrail encloses the opening where the stairs come through the floor for increased safety and prevents items (and people!) from accidently falling over the edge.

Lower Level of Mega GarageOn-Site set up time for this extra large garage is only about 1 to 2 days!!!

The second floor has a lofty 8' ceiling height creating a cavernous expanse for...

  • Storage
  • Workshop
  • Studio
  • Shore House
  • Hunting Cabin
  • Living Quarters

 This incredible garage with living quarters has one more amazing option... Have us install 5/8" plywood flooring in the truss center for a 3rd floor crawl space storage area. Access comes with a set of pull down stairs. Upgrade to a 6-pitch attic truss to squeeze out every last inch of available space.
