The trick to if rules are rediculous or not is enforcement.

"No storing wood" is a prime example of how this could be abused. Having a pallet in the corner to keep stuff off the floor or a 2x4 propped against a shelf shouldn't bring the wrath of Airport Authorities, but a big stack of random lumber is a rodent's hotel and shouldn't be allowed.

If building is allowed, a lumber rack for wooden planes should be able to get a quick blessing.

Of course all of this assumes that the airport people actually look at what's going on in hangars.
