Here are some links around the blogosphere that relate to workspaces.
10 seeeeeriously cool workplaces – A nice list that got pretty popular a few months ago, some of these workplaces are the definition of cool. Pixar, Red Bull, and the Mind Lab top the list for me.
Kithaus K3 [Coudal Partners] This is a beautiful modular structure (9′ x 13′) that can be used as an office, studio, mediation room, etc. Put in the right spot, this would provide an amazing link to the outdoors while still having all the amenities of a proper office. No word on pricing but you can find out more at www.kithaus.com.
CUBEDOOR [lifehack.org] – Not as stylish (or functional) as the sliding door in Topo by Metro, CubeDoor is one solution to a common problem. While this technically provides a door, I don’t think it does anything for privacy and will probably hurt your social appearance in the office. I see its best use as a good gag.
Wall-Sized White Boards – For those with a larger office, this is a really neat (and cheap) solution to create dry erase walls. The only cool thing left would be to make it magnetic. One comment suggested magnetic primer, but I’m not sure how that would work.
