That's pretty cool Nosedragger!
I guess I have the smallest hangar so far, 28' by 40'. 10' high door is all. Plenty big for the type of bird I fly. HydroSwing door, it'll open with any amount of drifted snow, I just make sure I clear snow away before closing else it compresses to ice in the jambs. For my setup this door is the best, I really like the big shade awning in the summer plus all the windows you can frame in it, plus a man door.
But, it is just down a flight of inside stairs from my 40' by 40' shop, built into the hillside below. The shop has a full bathroom complete with washer and dryer (that's also the laundry room for the house) and a 14' ceiling with beam trolleys and chain falls. I really like being able to weld or run the table saw or both, and then go downstairs and open the door to a clean airplane. I also have a lot of business visitors that I can receive in the shop without having to have them come into my house. They don't even know I have an airplane until I feel they are worthy enough, ha ha, then I take them downstairs and it's always a hoot when we walk in the hangar, great fun! Where's the airstrip is usually the next question.
I have outbuildings for misc/junk, just unheated polebarns for that stuff. No use cluttering up the prime real estate in the hangar. All structures except the outbuildings have radiant heat floors, solar thermal, a homemade wood boiler, and electric boiler for the heat source. Underground insulated piping allows all the heat to be channeled wherever as needed: all to the hangar if I know in advance (a long thermal lag time) I'll be working there, all to the house when really cold, usually some split between shop, house, and hangar. The shop has large south facing windows so if sunny it'll keep in the mid to high 50's all winter. The hangar never goes below 42 or so, (no south facing windows there) usually mid 40's to mid 50's, all for free. It's walls are 8" concrete right up to the ceiling on three sides, with spray foam on the inside then furred out with 2x4's and sheeted with OSB for something I can staple pictures and maps to. A 6 KW electric heater and a ceiling fan can make it t shirt comfortable once that concrete floor is not cold. Earth bermed on three sides it stays nice and cool in the summer also. It's small but big enough and comfortable year around.
A 6 KW solar electric array (3 actually, built up over time, for 6 KW total) a 2.5 KW wind turbine, and a 800 watt micro hydro pelton wheel (from April to late November it runs 24/7) all direct grid tied to Idaho Power. No battery backup, if the grids down I go into Inkom and drink beer. 100% electric, no propane. It's out maybe 20 minutes a year, damn it. I was off grid, by necessity, for 28 yrs on my previous property,, the new place had lines close thus the grid tie is the best of both worlds. I haven't paid a power bill or a heat bill for well over 30 yrs.
Nizina: My Honda welder/generator was my best friend when I was off grid, they sure make good small engines!
