I have a place leased at my local airport ans I have enough space to build two 60x60 hangars with about 40' between them, or I can build three 60X60 hangars with joined walls. I will sell 2 of the 3 units. Has anyone seen joined hangars of this size in the past and can you please weigh in with your thoughts pro's and con's?
Fewer walls to build and less cost would be the advantage of joined hangars, obviously. Another advantage is less land use and lower lease cost if you are leasing the land from the airport. The disadvantage is that a fire in one hangar could spread more easily to the others.
Joined hangars would be substantially stronger if you are in an area that has severe weather. I know of a couple of hangars that have collapsed on airplanes in Texas.
On the other hand, joined hangars increase the risk of a fire spreading.
Pick your poison.
Watch out for the dreaded "autocorrect" for I have experienced it trying to change my hangar to a hanger!
I have a stand-alone or free-standing hangar btw with neighbouring T-hangar owners telling me that they would prefer mine to theirs.
I also have a stand alone hangar, and have friends in T's, that all things being equal, would prefer to be in mine. Having said that, all things aren't equal. The cost being the main thing, and especially now. The added space in a conventional hangar is a big plus for me since even though my plane is the main occupant, I also store a couple cars and a boat in there as well without having to move any of them to get the plane in or out. I would think that the three side by side hangars would be both the most economical, most usable, as well as the most saleable. I am wondering how the roof would be configured with three shared wall hangars . My friends in the T's also have issues with snow and rain sliding off /falling in front of their hangar doors. On my stand alone, it falls off the roof to the sides, with the bifold on the gable end. Just a few more considerations.
another important factor is your local fire marshal. Three joined hangars could trigger significant costs in fire sprinklers and fuel spill containment set forth in NFPA 409 And first responder radio signal booster per IFC 510. have an early meeting with your fire marshal and bring a floor plan, elevation and a complete list of building materials.
