That "garage" is actually an airplane hangar. My brother has 1 for his plane. Notice the recess in the center of the rear wall. That is for the tail. His hangar door is a bifold or trifold horizontally to open it to the outside. And that is about the same speed as his opens.. In fact it appears that maybe the front is just a facade that is attached to the folding door.
And yes he keeps more that just a plane in it. In fact he can pull the 4 sled enclosed snowmobile trailer inside to service the wheels and axles. Heated with gas. And a fridge for when he lands. He was looking to get a remote phone operated control for the heater to be able to call in and heat the plane before he would want to fly somewhere.
At the same airport, Heritage Field, in Limerick, PA there are auto related businesses in there and of course the local FAA approved and certified plane repair center. His hangar backs up to the plane mechanic. They are good friends so servicing the plane is never an issue for him.http://www.airnav.com/airport/KPTW
