B> balcony area, dressing room, prop room
The word, “tiring” of “tiring house” is based on the root “tire.” At first, the word may look foreign, but when we realize the root “tire” is in the word “attire,” it begins to make some sense. As you may know, “attire” means clothing. Thus, “to tire” would mean to put clothes on. And, a tiring house would be a sort of dressing room where props, too, could be stored or immediately accessed in order for actors to include them with their costumes while they dressed. The balcony area would generally be located near the tiring house (usually directly above it).
