Hideaway home office already built?

[MumofSpud]

Is it impossible to get a hideaway home office unit that is already assembled / built?

Um. Only the very dainty flimsy ones. Anything substantial would come disassembled as the assembled piece wouldn't fit through a doorway.

Something like this:

looks like it might come all assembled but you'd still need to wall mount it
