Trivia: In the final scene of the film, as Tony is unfolding the blueprints for the new Stark Tower, if you look very carefully (slo-mo may be necessary) you can see files with a symbol representing each Avenger in the upper right corner of each file - Captain America's shield, Thor's hammer, etc. The implication being that Tony will build a section of Stark Tower for each of his friends.
