Having seen the nice new building you live in from the outside, I think you must resort to an offsite storage solution. Otherwise, I would suggest acquring some bike frame boxes, which are smaller than full bike boxes, and just stashing them in a closet or under the bed.
Maybe a bellman's cart which has the clothing rod on top? Also, the apparel carts you see pushed around midtown in NYC in the garment district. Then you roll em out of the way when guests come. Or this.

If you want to display the frames:
Threaded Iron pipe, mounted wall to wall with escutcheon plates. Use shower rod plastic covering to give them a chrome or white look.
Bar foot railing or retail slatwall with hooks from ouwaterplastics.com off I-80 in Bogata Bergen County.

Metro wire rack shelving wall mounted high. Hang frames from shelving.

By the way, tell your neighbor Ely the QB, to get his sh|t together.
