1、Planningthroughinfrastructuredesignanddevelopment:

wallingthecity（1550s）,expandingthewalledcity（1870s）andbuildinganewurbaninfrastructure（1930s）.Theywereallledbythegovernment’sabilityanddesiretoinstigatechangeandshapethecitythroughundertakinglarge-scaleinfrastructureprojects.

Thefirstlarge-scaletownplanningexerciseinTehranwasundertakenin1553,withtheconstructionofabazaarandcitywalls,whichweresquareandhadgatesonfoursides,inaccordancewiththepatternofancientPersiancities.Thissettheframeworkforotherdevelopmentsthatfollowed,andthecitygrewinsignificance,eventuallytobeselectedin1785asthecapitaloftheQajardynasty.

Onbecomingthecapital,thecityswelledbycourtiersandsoldiers,whowerefollowedbytradesandservices.Fromapopulationof15,000attheendofthe18thcentury,Tehrangrewtenfoldbythe1860s,witha10thofitsinhabitantsnowlivingoutsidetheoldwalls.Thecountry’smilitarydefeatsinitsencounterswithBritainandRussiahadengenderedaprocessofreform,whichwasnowbeingextendedtothecapitalcity.Thesecondlarge-scaletownplanningexerciseinTehran,therefore,wasconductedforaccommodatinggrowthandintroducingmodernizationandreform.Startingin1868andlastingfor12years,newcitywalls,intheformofaperfectoctagonwith12gates,wereconstructed,whichweremoreusefulforgrowthmanagementandtaxcollectionthanfortheirdefensivevalue.Selectionasthecapitalcityandthesetransformations,whichincludedanewcentralsquare,newstreets,abank,aninstituteoftechnology,ahospital,atelegraphhouse,hotelsandEuropean-styleshops,were,accordingtoaBritishobserver,a‘‘twofoldrenaissance’’forTehran.
