If Bandon Oregon is growing, or has any potential for growth, build the biggest and tallest hangar possible to put on the lot size, with as many doors as possible. This will get you the biggest resale value and make it easy to sell when the time comes.
I'm just finishing up my hangar, it's on the corner of two taxiways, 80'x105' - can't remember how high but asked for and received a variance to go higher then the airport rules. Three Higher Power doors; 70ft, 56ft, 45ft. 10ft rollup door. 3-piece bathroom. Fully insulated.
Total cost, including the land purchase, $350,000. Been offered $500,000 for it, realistically worth $600,000. Not for sale (until I'm done flying). Value will only go up as growth in this area is exploding.
Plan on adding 4,000 square feet of solar panels to sell electricity I don't use back to the utility company. Plus put a couple of low-wing renters in to pay for ongoing hangar costs/fees.
Good luck with your build, and enjoy!
