In D.VA's closet is a hidden door behind where clothes are hung, and entering finds one in a large, expansive room with fluorescent lighting and a single gigantic stainless steel table against the back wall similar to the ones found in the kitchen, complete with cabinets and drawers filled with tools and various boxes of scraps.

The floor is largely tiled and scuffed, but in the center is a raised platform with a rack that is configured to secure a single person sized mech with the press of a button (mech not included, unfortunately!).

Aside from those features, one large workbench each sits against the left and right walls, with a variety of monitors that display random technical info and provide various options for controlling the room's lighting or controlling its radio. They are also capable of playing any movies that the room's owner has on their phone, purchased from the points shop. On the wall above each bench is a sheet of particleboard with hooks riveted into it to provide easy access to tools. Horizontal display cases flanking each bench have variations on the room owner's Henshin armour, though they're all nonfunctional.

A single plain couch sits in front of the mech storage pedestal.
