Because of the fame and safety of Athens and also developing construction industry, the population became really overcrowding. However, vast majority of Greek cities were small in size and they look really unpretentious in appearance but when several villages became united as a single community, quite enough of them were self-sustained and the polis comes into existence. In my opinion, the society was democratising. They all had some responsibilities in society.
The Greek houses turned inset like Mesopotamia. I mean the courts were not looking outside. The rooms were not definitely defined in terms of function. However we can see some functional differentiation. For example, the andron was more like a public space (main dining room and entertainment room).
The normative grid provided a straight way to divide the land, shape the structure of the city and also control future growth of the city. In the Greek, the grid system lined in the social superiority of a title holder class. Orthogonal planning is as old as Egypt. However none of the Greek grids can be considered completely planned systems of public and residential structures with coherently organized blocks but at the same time the grid determined the size and the shape of public buildings, temples etc. There was really strict grid layout that adopted city. Hierarchically agora which is the open gathering place have higher importance rather then the other structures. Agora was the public meeting and marketing place in the city. There was also public gathering which is called Stoa. It provides an open space without fully enclosed it. It was used with various purposes like shopping, accommodation for travellers etc. Stoa consists of long row of columns defining long aisle ended with a back wall and roof.
Miletus was located on the hill and it was using really advanced grid system and its planner was Hippodamia who believed to be founder of grid system.
