Introverts tend to draw their energy from long stretches of alone time. To determine whether you might be an introvert, see if you can understand these 27 problems.

Susan Cain, author of Quiet: The Power of Introverts in a World That Can’t Stop Talking, understands how introverts must suffer amid the loud munching on Trader Joe's paneer tikka and the cacophony of the "ideation sesh" unfolding a few desks over. She has partnered with Steelcase, the office furniture maker, to create new types of office spaces that will allow introverts to both work and respite in peace. Some of the new modules will house desks, others will contain couches, and others still will have yoga mats. All will have walls.

"These are spaces where people can innovate," Cain told Fast Company's Ariel Schwartz. "Solitude is a crucial ingredient in innovation."

Each room is built with glass that, according to Steelcase, is 100 percent soundproof and whose opacity can be adjusted for added privacy.

Below is a look at some of these spaces:

The first prototypes will roll out this month at the NeoCon design conference, and they will start being commercially available this summer. The rooms start at $15,000 a piece. Of course, if your boss had that kind of money to spend on your work habitat, you probably wouldn't be in an open office to begin with.

Update: Steelcase shows what the offices would look like with the opacity on the glass dialed up:
