box room office feng shui?

hi there. im turning a box room 2m x 2m into a box room, theres a door in the back left corner with a cupboard (built in) next to it on the opposite wall theres a window. the window looks out to the east, the room is on the 2nd floor at the back of the house above the kitchen and with a bedroom next to it (phew) anyone got any tips on how i can get the best from this tiny office?

a simple corner desk might do the trick. anything along these lines or smaller…
