Alex Johnson of describes these little rooms within larger rooms "indoor shed working"; we used to call them cubicles. While as an architect I was always used to working in open space, sometimes these can make a lot of sense, like in a noisy machine tool trade show like Lamiera in Bologna, Italy a few weeks ago. Salvagnini, a big Italian manufacturer of metal cutting and bending equipment, knocked these up as private meeting rooms. They are rather nicely done.
They are made with a fairly elegant steel frame, held together with pins and reinforced with diagonal bracing on one side.
Natural light is brought in through double layered plastic, what used to be called Rohaglas or Chemacryl SDP.
I really cannot tell if all the detailing is there for a functional reason or if it is just for looks; It doesn't look like the unit folds up or anything. I tried to ask, but all the salespeople either didn't speak english or didn't know.
The interior is utilitarian and unexciting, with a small air conditioner through the wall.
But from the outside, I thought they were an attractive and effective way of dealing with the problem of needing privacy in a very public space.
