I know that there's a well established rule of thumb that states close collaboration just doesn't tend to happen beyond 30??? feet or a single staircase (i.e. people further apart just don't tend to collaborate). This is of great interest to universities and other places that do research, you should be able to find something, maybe in Peopleware (which if you haven't yet read you want to anyway).
True. However they also say: "...enclosed offices need not be one-person offices. The two- or three- or four-person office makes a lot more sense, particularly if office groupings can be made to align with work groups."
I think there needs to be a balance between private/semi-private team space and individual private space within the team space.
Indeed. It was, however, written in a very different period of software development and one could argue that it may be less applicable to the the "bolt things together", MVP consumer product/site sort of project that is the greatest?/primary?? focus of HN/YC/today's angels funding.
(To emphasize how different, we can be pretty sure that very few if any of the programmers studied had a memory budget even close to what's been in mainstream CPU caches for some years.)
For another example, see MIT's termination of SICP/6.001/Scheme with extreme prejudice and replacing it with Python based "bolt together" course(s) (I don't know anything about 6.02, but the initial 6.01 robot project is just that ... which is not to say that it's easy, e.g. it requires the use of differential equations and its labs are very instructor intensive, to the point the department is recruiting upper-classmen to help).
MIT believes that things have fundamentally changed....
