Size
Size is a general statement.- Small quarters are suitable for 1 or 2 heroes with a small amount of equipment, and has 2, maybe 3 areas or rooms.
- Mid-sized housing is suitable for 2 or 3 heroes, any support crowd (offices would fit into this area), and runs no more than 5 areas or rooms.
- Large is suitable for a number of heroes and equipment, and has 10 or more areas spread over 2 floors.
- Deluxe is the largest size, and is for heroes with several vehicle types, trophy rooms, and living quarters. It has 20 + areas spread through 3 or more floors.
Spider-Man's lodgings are an example of Small dwelling. The Heroes for Hire offices were Mid-sized, the Angel's place used by the Defenders in Colorado Large, and the Avengers' mansion, Baxter Building, and Doctor Strange's sanctum sanctorum are Deluxe. (The last measures interior size, not exterior.)
