Sheldon and Raj's Office

Sheldon has used two offices in turn at Caltech.

Sheldon's first office
Sheldon's first office features a series of book shelves and white boards, and originally, Sheldon has a small desk placed opposite to the door. The office is to the right of the Lecture Hall and to the left of (rooms?) A1 - A5, as a sign at the right side outside the door indicates (the sign can be clearly read in The Hot Troll Deviation [S4E04] when Howard and Leonard approach this office at 15:46). And a tap that supplies drinking water is located just outside the door, at least in The Porkchop Indeterminacy (S1E15)

This office firstly appears in The Jerusalem Duality (S1E12) when Sheldon "gives a tour" to Dennis Kim. He meets his twin sister Missy in this office in The Porkchop Indeterminacy (S1E15). The office also appears in The Griffin Equivalency (S2E04).

Since The Pirate Solution (S3E04) Sheldon begins sharing this office with Raj when he hires Raj to "work for him". In The Cruciferous Vegetable Amplification (S4E02), the office was shown briefly when Raj opens door for Sheldon's "Shelbot". In The Hot Troll Deviation (S4E04), much to Sheldon's dismay, Raj gets a giant desk which Sheldon describes as "brobdingnagian monstrosity" into the office, and occupies the original position that Sheldon's desk used to hold; and Sheldon's own desk is moving closer to the door. In The Good Guy Fluctuation (S5E07), Sheldon was scared in this office by the "pre-Halloween hijinkery" of Leonard, Howard and Raj. In The Beta Test Initiation (S5E14), Sheldon was seen for the last time to work in this office with Raj.

Sheldon's second office
In The Rothman Disintegration (S5E17), Sheldon beats Kripke to win the retired Professor Rothman's office as his second office. Inside the office there are at least two whiteboards, a large window that opens, desks, air vent to the right of the desk, a sofa, bookcase, and filing cabinets, while a poster of a supernova is seen to the left outside entrance. When Sheldon moves in, several faults with this office drive Sheldon crazy:


 * The low temperature that Sheldon cannot adjust, because the control of the thermostat is not in this office but in the next door, Prof. Davenporter's, who set the temperature low due to "the hot flashes associated with menopause";


 * A hole on the wall;
 * Sound of wind chimes outside the window;
 * Sound of a mocking bird which is "completely out of the tune with the wind chimes";
 * Noise of the sieve shaker of the Geology Department from downstairs;
 * Prof. Rothman still appears in the office naked, from time to time.

. Later, in The Higgs Boson Observation (S6E03), Sheldon is seen still working in his second office.
