You are the second person I have ever known to mention an Attic Lift, I did a very large hangar, RV dock, 4 bay garage and 2 bay lift addition about 10 years ago and the home owner requested an Attic Lift, exactly as shown. I've done plenty of fixture lifts but it was the first and only attic lift for this Ole Sparky...I bought a little house with a huge garage. It’s great.
However, the garage wasn’t heated, which is a big problem.
So I called an HVAC company and had them run a duct to the garage and now it’s heated and air conditioned. I love it!
The next project will be an attic lift and pull down attic stairs.
