Location, location, location, the real estate folks tell us. And the prime location for an office in Washington is the West Wing of the White House. With that in mind, we’ve updated our interactive map of the first and second floors of the West Wing to show who’s sitting where.

One thing regular readers will notice is that about two-thirds of the people now closest (in terms of proximity) weren’t in those spots when we first launched the map in January 2009.

Some, of course, were at other agencies — Gene Sperling was at Treasury, for example — while others were out of government, such as Communications Director Jennifer Palmieri, who was at the Center for American Progress.

Other officials, such as Denis McDonough, have moved up from the White House ground floor (not shown on our chart) to a small office as deputy national security adviser and now to the relatively spacious chief of staff’s office down the hall from the Oval Office.

Alyssa Mastromonaco, former director of scheduling and advance, also was down on the ground floor in 2009, but as deputy chief of staff, she’s now moved right next door the the president’s study.

Many jobs — for example, the legislative affairs post — have turned over more than once since Obama moved in.

With the dust pretty much settled since the transition — there’s only one office, in the communications area, that’s not filled — the team seems pretty much in place for the second term.
