Which of the following would you least prefer to locate adjacent to a lobby?

Locating a garbage chute adjacent to a lobby is typically less preferable due to the potential for unpleasant odors and unsightly waste materials. The lobby area is usually designed to be welcoming and comfortable for visitors, and having a garbage chute nearby could detract from that atmosphere, creating a negative experience as people enter or exit the building.

In contrast, service stairs, elevator entrances, and lounges can generally be integrated more seamlessly into a lobby design without compromising the overall aesthetics or functionality. Service stairs might be necessary for efficient vertical movement within the building, elevator entrances facilitate accessible movement, and a lounge area enhances comfort and social interaction among guests. Thus, the garbage chute stands out as the least desirable adjacency in this context.
