our rules > endless urban structures:
_2 directions given by urban elements
_1st step of occupation is supposed to be just on the first level
_base unit - a functional unit (2X3m)
_lot dimension = 8x basic unit = 48 sqm
_1st step of lot occupation=3"living"units+1infrastructure unit+2green units+1stair unit+1"waiting"unit
_max. lot occupation=2green units+1stair unit+10units, selected from:3 infrastructure unit and "living"units
_the infrastructure box is plugged to the infrastructure line and has to have 1side facing directly the oustside.
its position during the expansion process is defined in the 1st step of occupation.
_ about 2500 US dollars per family = 30sqm = 1 infrastructure unit + 1 stair unit + 3"living units"
_ about 2500 USdollars per famlily = urban elements + 2 green units
_ about 2500 US dollars per family = land cost
_ elements contributing clearly for the urban drawing : 
public areas+infrastructure lines+green structure+stairs[for roof use and defining the expansion process]
_ space for community activities > minimum = 192 sqm .:. maximum = depending on the available area  
_the strategic urban elements of the urban shape should appear as an action-reaction effect 
other conditions will come with the story of each place - surroundings, persons, climates
