Kostof, S., & Castillo, G. (2014). The city assembled. New York, NY: Thames & Hudson Pg.189-230 This reading talks about the different kinds of streets that have emerged or evolved through history. It talks about the evolution of the elements in terms of their morphology and usability. There were different aspects that used to and still are taken into consideration during the creation of these streets, some of which are culture, class, public health, traffic and aspects related to these and many more. For instance, in case of Islamic culture, the sanctity and privacy of the women is always a priority and to hide them from the eyes of the public, the ground floor used to be shops with balconies above such that the women could see what is happening on the outside but the passerby on the street won’t be able to see the women. While such factors do cater to giving a certain characteristic to the street, the desired characteristic always seem to remain a utopian idea as said by the author.

GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | POSTER
This is the initial phase in which we studied the physical,social,and climatical aspects of the calico mills land as well as its surroundings.we broke these topics down into further parts studied them individual and also found inter relationships between them .All the information (Qualitative and Quantitative) gathered was quantified. Quantification Would help us further to compute our design proposals.In order to analyse the quantification,we used grasshopper plugins like ladybug(for density ),decoding space(for degree centrality) and a few others

SITE ANALYSIS
GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS
Understanding the build and open spaces and how is the landuse in the area,relationship between various uses and their distribution.Landuse evolution-Analyzing the past and present historic patterns of the landuse at different scales from patches to blocks So the basic aim of this analysis was to understand the interrelationship

GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS | LANDUSE
The above maps shows the impacts on arterial streets which is due to the vehicular movement and presence of informal market under flyover
The above map shows how street are getting affecting due to kind of landuse present over there.Here,presence of institutional and commercial building is what making the streets active and generarating more vehicular mements
The above map explains the flow of pedestrian and vehicular movements due to the presence of informal settlements.The collector street remains active throughout the day due to the continuous movements from local streets
GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS | LANDUSE
Open spaces: The distribution of the open spaces is 27386 sq mts in the site area which includesgraveyards,some unused open spaces,towing ground
Public services: The distribution of the Public amenities is 34,970 sq mts in the site area which includesgovt services such as crematorium,police and fire station etc
Industrial: The distribution of the Industrial part is 110061 sq mts.in the site area which includes both the production units and the warehouses.
Institutional: The distribution of the institutional building is 51,487,575 sq mts in the site area which includes educatinal building,religious,health and recreational
Commercial: The distribution of the Commercial building is 51276 sq mts in the site area.Most of the commercial part can be seen on the street edges
Residential: The distribution of the Residential part is 22,7,916 sq mts in the site area which includes the formal settlement of the different building typologies,informal settlements and slums
GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS | LANDUSE
The analysis period has been based on an approximation made on site observation. The map divides into two broad categories which are Resident and Floating. These are simply to see what amount of the site remains as populated and to relate it to the activities, uses and typology over the given set. Jamalpur has dense populated residential areas and with a major portion of it’s commercial grouped into the southern sector.
GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS | POPULATION DENSITY
GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | SITE ANALYSIS | POPULATION DENSITY
Similar situation as section 2 with the chawls making up for most of the site density. The built heights are low rise hence the density. The mixed use condition gives rise to more resident population over commercial density.
Population density in the section show a prominence of floating population and a stark difference between built propotions and occupied spaces.Landuse and density map coincide with the other as commercial spaces are infact a flux
The proportion of residential is far more than the floating population mostly because of the chawls in the setting. Sheetal Varsha though the largest commercial building it has low density.The whites here are mostly the street, the reds are part of the chawls which are densely packed.

This Analysis is for studing the patterns and functions of the street with respect to the other layers of street like landuse,street Hierarchy,public and private transportation network and predesrain network
1. The anganwadi is at a walkable distance for the neighborhood communities and they mainly use the internal streets to access it.
5. Mosque is used by a specific community only which are mainly the locals of that area who walk up to it every day.
3. The slum areas on the edges use AMTs for their daily commute to work 2. The pan galla acts as a gathering and travel. They walk up to the stop space by men who walk through the which is within 500m radius. local streets to socialize. Auto rickshaws are also concentrated on this side. This is were they stand. 4. School is located on the edge on a junction of an arterial street making it a busy area generating traffic. Students either come walking or cycling from the internal streets or others coming from outside the area come by AMTs.
7. Warehouse is located on the local roads of industrial areas where workers walk to it from the bus stops near to. The use the shortest pedestrian routes to reach the warehouses.
8. Apartments are accessed mainly by private transport and the auto rickshaws also stand there outside it for the people to travel.
6. The industrial area has many workers who come by AMTs or BRTs and then walk up to their factories through the collector roads.

There are certain speciďŹ c factors that contribute in making the frontage active. Varying setbacks create interesting edge conditions leaving opportunity for informality to unfold. In slums, setbacks give enclosure to a space, transforming them into semi private spaces with otlas and khatlas to proliferate, giving rise to everyday household activities. Similarly, along the commercial and institu-tional edges, setbacks accommodate small shops and pan gallas introducing public interaction to the space.

In long straight street we have a longer visiblity but because of of depth is felt. This is one of the major street which connects the artiler and sub-artiler street which is about 450 m away from the parallal street which makes this block into walkable distance This juction acts as the entrance for the site as it has police station at one side and quite a large street opening to this street
H which is on the only street in this area which go through the NALA because of which we can see people coming to this side of the area
This is the one of the major junction of the site as it has pan galla on one side and the general stores on the other so this become one of the most active junction
Permeablity for me is the freedom to move around without any constraints and to go around smoothly.It gives an individual a choice of choosing the path he/she wants to take. coming on to my site there are two parallel streets running from which one is arterial and the other is sub-arterial.There is a collector road at regular interval at a walkable distance .The arterial streets have long coverage visiblity and the collector road which cuts this main road helps in forming walkable blocks.The street creats an enviroments and an experience for the pedestrians and passerby by facilitaties like tea stalls and pan shop making more social gathering possible.Hence ,more people prefer that route making it more permeable
Vatva is located around 28.9 kilometer away from its district head quarter gandhinagar. The other nearest district head quarters is ahmedabad situated at 26.6 KM distance from Vatva .
There are two types of urban grains visible on my site one is course grain which is seen in the industial area and ďŹ ne grain visible in the residential areas

Analytical plugins are tools to study and analyze conditions of the surrounding affecting our physical and social comfort.in the grasshopper ecosystem we have made use of ladybug and decoding spaces as plugins which is a toolkit that helps perform climatic visualization,thermal analysis and quantify spaces respectively. The analysis is performed on six different patches of ahmedabad fabric,5 are from our main site calico mills and one is dhal ni pol,used to understand the contrast between both sites climatically and socially
ANALYTICAL PLUGINS
SOLAR RADIATION A common inference drawn from this patches is that usually building blocks which are compactly oriented experience minimum thermal radiation and remains cooler, e.g.: Dhal ni pol, its narrow streets and organic orientation of houses produces more shadows which shows that the amount of incident radiation is less and mostly reflected radiation is experienced by the walls of the houses thus they remain cooler even in summers and also people often tend to use outdoor spaces even in summers for theirwork and leisure.
WIND ANALYSIS According to several climatic studies wind velocity beyond 5m/s is considered beyond human comfort and inappropriate for any activity. Dhal ni pol Patches are low rise residential areas in which the wind velocity reaches to almost zero when it reaches open spaces (chowks and some junctions), and hence can be assumed that during this month inner streets and chowks would notbe comfortable spaces to be in.
ISOVIST As a comparative observation, open spaces and wide streets are visually less complex as compared to the inner private spaces as number of obstructions are less which sets the level of privacy and publicity. Hence, the types of activities performed, change its nature accordingly

Evolutionary computation processes area focused on understanding the process of evolutionary development and mimicking it to generate various forms evolving from a “tool kit� of genes.complex forms and systems can be produced through the develpment and modification of the genes,at different stages in the time and different parts of the body plan,to obtain a family of solutions which behave differntly in relation to various functions and fitness criteria.through computation,the key concept of breeding,crossover,killing and mutation stategies are translated and applied in order to develop experiments able to produce multible variations

Fitness Criteria
SUPER BLOCK
Evaluating fitness criteria is both at an individual block level and how that block functions in a neighbourhood i.e. superblock.Here,on the basis of the values of all the fitness criteria of individual block,certain individuals have been grouped together in order to categorize specific uses for each superblock Further evaluation of the fitness criteria of these superblock through evolutionary computation is necessary in order to understand which individuals are catering to the better performance of the superblock

In the next 20-30 years urban population explosion will demand 3000 new cities, with maximum of these in South Asia. A major concern within these is to incorporate de sity and a mix of program without compromising spatial quality and comfort in order to cope with climatic changes. The site chosen for the main project is the derelict area of Calico mill lands and its surroundings. Through the studies of urban tissue samples and the analysis made of the interactions across various hierarchical levels within the built fabric, develop a generative set of rules at neighborhood scale, using a strategy for urban intervention based on the readings of the site and the context. Eventual aim will be the design of an urban tissue and its systems, and the detailed design of one ‘cell’ within it.

GENERATIVE TECHNIQUES FOR URBAN PLACEMAKING | HOW?
Pols are enclosed residential clusters entered by gates, which used to be shut at nights.The essence of a pol is a network of small streets, side lanes, shrines and open community spaces with a chabutaro, a birdhouse raised on a pole to feed birds in the neighbourhood. These neighborhoods have their own urban structure which is self sufficient for the communities, where each ‘Pol’ is also a self sufficient unit. As the individual Pol is an entity by itself, the neighborhood is also an entity at a larger scale. So the progression goes further, which gives the city an urban pattern consistong of these neighborhoods that downscale to a house.
