I love the LEGO Architecture series (as does my son Jamie). These micro-scale builds are not only remarkably accurate to the building they are based on, but they come with a cool booklet that gives a lot of background information about the building.
Set 21006, The White House is a good example of what the Architecture series is all about. Because of the small scale the details are obviously limited, but once built you have something that you could very easily sit on your desk or shelf for display.
Plus it's thematically appropriate for the day!
