I'm in the midst of what seems like a never ending research project on some of the great Georgian squares in London. I am trying hard to understand as much as I can about the design of squares, and the Georgian squares of London are more of a vehicle as opposed to an endorsement. I am working on several actual projects currently that include “squares” and so my interest is particularly keen with regard to dimensions that work and those that do not. But the other issue I am exploring is the connectedness of squares in predominately mixed use districts, and that too makes the London squares in Belgravia, etc. potentially helpful since you can “kick the tire” on twenty differently shaped squares in roughy a half mile radius. Plus, the average walking distance between the London squares surveyed is only 586 feet - I think a very remarkable frequency for an area very much developed by thoughtful speculators. Noteworthy.
