With well-calibrated grav belts, and a calm environment, you could create a holographic building, with insubstantial walls, floors and ceilings mainly being there for privacy reasons.
Well-programmed grav belts could avoid faux pars like passing through holographic architecture.
Possessions would prevent challenges as you can't place things on holographic floors or furniture without it falling through. Grav desks and tables, working on broadcast power might offer some relief.
Potentially such a system could be city- or planet-wide with the locations of holographic barriers, and other supplementary rules, broadcast to all grav belt users.
