Is there book or research on economically sustainable design of town or village? I'm looking for a book which may help to design a self-sustainable small  settlement, which can maintain its own economy with limited connections to the outside world. Prefereably it should answer questions like:


What population is sufficient for such a town or village?
How to model microeconomics of such a settlment?
I would suggest the Handbook of Regional and Urban Economics. It currently has 5 volumes and collects papers on the theories and empirics of urban/city design. Selected chapters that may potentially address your questions include: 


City size and place as policy issues
Financing urban public services
The theory of urban residential location
Therories of urban business location
Urban labour markets
Urban housing markets: Theory and policy
Micro-Foundations of Urban Agglomeration Economies
