If the compiler didn’t catch it, doesn’t that say it was modeled incorrectly?
Why not have an IAirSpace interface or an abstract AirSpace class with two specializations? If there were processes that could handle either it should take an AirSpace class, one that could only handle one or the other took the specialization.
If the steps were the same for handling both, have step1...step(n) defined in the concrete class and have a coordinating “service” that just calls the steps and takes in an IAirSpace.
