Preface This studio will focus on the design aspects of urban transformations within the existing
urban areas. The underlying context is that Indian cities are growing rapidly in terms of population and therefore expanding physically. Increasing urban population and the growing urban incomes will fuel demand for more and more built-floor space in cities accompanied by a demand for infrastructure.Many urban areas within these cities are dealing with unstainable levels of stress on infrastructure, resources and public services and are becoming increasingly unliveable.
As an attempt to address these concerns, the Ministry of Housing and Urban Affairs
(MoUHA) has initiated various schemes such as AMRUT (Atal Mission for Rejuvenation and Urban Transformation), SMART CITIES MISSION and HRIDAY (Heritage City
Development and Augmentation). These schemes enable planning for developing infrastructure in the brownfield areas through mechanisms such as Local Area Plans (LAP)
and Town Planning schemes (TPS). These typically include those parts of the city that area already developed but are not able to sustain the pressure of existing infrastructure
Students will work on the projects that are emerging out of these initiatives defined by their studio tutors. Through their design projects, students will explore the methods of
integration of the physical design with the regulatory frameworks (TPS, LAP) in creating liveable, functional, memorable, safe and sustainable urban areas. The projects will
have a strong design focus on the physical setting, however issues of private ownership and social equity, land economics, planning models, project finance, and implementation strategies will also be addressed.
The learning outcome of the studio will be to: •
Prepare strategic framework plan of delineated areas with identified design projects
•
Prepare building regulations for the intended urban form outcome for the project
•

Local area plan - Ahmedabad
AUDA has demarcated a 200m zone on both sides of the metro corridor as Transit Oriented Zone (TOZ). All TOZ zones will be eligible for an increase in FSI. From FSI of 1.8, the new permissible FSI will be 4 for all Metro and BRTS corridors. Within these zones, AUDA has initiated local area planning (LAP) since 2015. LAP aims at developing a framework for improving the public realm (public spaces, areas under roads etc.) by enabling retrofitting and redevelopment of the existing built environment and preparation of a new layout with enhanced infrastructure provision (Ministry of Housing and Urban Affairs, 2018). LAPs are developed based on the principles of TOD. According to AUDA (2017), TOD is referred to as a high-density mixeduse development along the metro corridor that will encourage efficient use of ground and front margins. 10

1b Site Context and background Site is located in the west part of ahmedabad near to sabarmati riverfront. Ahmedabad has three major public transport options within the city that are metro, BRTS and AMTS. Precinct is well connected with the major nodes and also provides connectivity to the east side of Ahmedabad through Ellis bridge, that is 10 min. away from the site. Also it connects the major growth centres with good public transport connectivity. The intension of the project os to explore the possiblites of urban expansion in a brownfield site at Paldi, Ahmedabad.we have analysed various aspects of the site and tried to retain the unique character of the place while improving the overall standard of the place.

1e. Case study This vision for Kabul recognizes Afghanistan’s rich cultural heritage while looking to the future. It captures the symbolic power of the city while clearly defining the elements that will bring regeneration and investment to Kabul as a whole. Nodes organized around transit stations propose specific programmatic and public realm strategies that create distinct regeneration opportunities along the boulevard.
Learnings 1. Establish three distinct character zones and urban design strategies 2. Defining the cultural elements that will bring regeneration and investment to Kabul as a whole. 3. Social Housing Interventions in public parcels.

2b Framework Stratergy
Strengthening the Accessibility Improving the Streetscapes emphaizing more on universal accessibility by three major stratergies which is careful integration of transit and bike lanes in the public realm. Also to encourage walking by integrating private streets into public streets.Also,linking missing connections to complete the loops of the network. The effectiveness and quality of street networks through redistribution of streets giving safe space for all users.

2b Framework Stratergy
Integrating Public realm Network The framework identifies stratergic public streets to improve the public realm along these networks through devising linkages with neighbourhood level open spaces by having complete street design and as a part of improving the green cover by converting underutilised spaces to parks and having bioswales along streets which improves the soil perculation to reduce stromwater runoff. Existing parks/ open spaces which area acting in isolation also have been integrated with the streetscapes.

Compact Mixed-Use Development
With identification of strategic nodes in our site, come up with districts that give varying character and experiences. Transit district having high rise mixed use typology treating it as a boulevard having Lower floors activated for commercial purpose. Mix district with podium building our strategy being devising built form regulations to allow for higher permeability along the building edge at the lower floor in the form of commercial and boulevard character. Finally Riverfront district, with high rises give visual connection to the biodiversity and riverfront. Strategies are formulating development control regulations by introducing green terraces at the ground floors to enhance the physical connection to the neighbourhood.

observe how communities have turned their back to the river,wherein the excellent opportunity this riverfront provides is somewhere lost.
Sabarmati river has been an integral part in the life of Ahmedabad since the time the city was founded. But as the city grew, the river bore the brunt of its development. it resembled any other Indian river of the day, polluted to a level where its water was no longer clean. Later efforts were taken to revitalize the river.Land has been reclaimed and redeveloped into city level public space where people of ahmedabad have access to the riverfront. But today, when we observe Paldi’s riverfront, we can
The proposal identifies TOZ LAP as an opportunity in exploring the possibility of connecting neighbourhoods abuting the river, physically and socially, and also programmatically bringing activities that would bring the river at the forefront of urban transformation and development. An urban waterfront has a special place in the modern resident’s heart because it connects them with nature. While reestablishing public space program, enabling outdoor gathering opportunities and improving riverfront accessibility.

3a Project Identification
Potentials to transform Waterfronts is an important defining element of public space across the world. when looking at the cities like Seoul,South korea have brought back a their waterfront by converting expressways into city level public space in the centre of the city. New york once it was a highway now it is tranformed into a riverfront park to bring river to the urban core.In case of Chicago river was just carrying sewage now it tranformed and brought into citi level central public space with waterfront activities to bring people close to river. we see instances like New york, Korea and Chicago wherein the transformation had led towards bringing their waterfronts central to urban development and its residents, in contrast to what we observe incase of Paldi and its riverfront.

3b Precint context National institute of Design
The Precinct is well connected to the CBD (Central Busines District) and to the city at large by the BRTS corridor running through the site. Biodiversity park marks the end of the riverfront project.Addionally, There exists scenarios of tourism as evident from the newly inaugurated seaplane terminal connecting various tourist destinations around the state. It has a good regional connectivity by ahving interstate bus termius in close proximity to the precint. Precinct is characterised by high rise development along the BRTS (Bus Rapid Transit System) corridor with the rest of the neighbourhood having predominantly low rise residential. Most of them are co-operative societies which built before 2000s, few are undergoing redevelopment.

Spatial Strategies
The strategies for the Rivefront open space was developed in conjuction with the overall Paldi Local area plan framework.The proposal identifies underutilised plot to tranform it into a neighbouhood level public space with integrating with the biodiversity edge. Along side,the riverfront street which act as a throughfare for the people disallowing the neighbouhood to connect with teh riverfront that can be addressed by converting certaing nodes to pedestrain oriented public realm which supports Paldi’s vibrant street life culture.Finally, to bring equitable acces to all street users, Neighbouhood streets are to be redesigned by carving out space from private realm.
1.Redesigning the existent under-utilized assets
2.Exploring possibilities for an active street scape and nodes to support Paldi’s vibrant street life culture. 3.Curating strategies to carve out more area under public realm

4b Street Revitalisation Spatial Strategies
The goal is to utilise a series of street network strategies to reconnect the riverfront and BRTS corridor for a more walkable core. Main concern for the same being one would not realise the presence of the riverfront until physically reaching it. And Street has encroached footpath by vehicle and street vendors. The proposal is to enhance the experience in the street by having continuous footpaths with trees and dedicated space for vendors and paid on street parking to control use of private vehicles and having dedicated bicycle lanes.
1. Inserting new connections to improve access of the resident communities with the transit boulevard and riverfront. 2. Creating a safe and pedestrian friendly street sections emphasising on universal accessibility.

5a Street network Once these projects are developed. precinct will undergo transformation by having more connections leading towards the riverfront and built form responding to its edge. The existing block size with an average perimeter of 550m. The residential blocks next to biodiversity park has streets forming culdesacs that can be opened up by establishing a parallel connection to the park. Finally, The proposed average block size 310m with increased area under public ROW 15.2% from existing ROW 11.5%. The street network craved from margins form the Future ROW where the plot owners will entitled to get incentive for original plot size. NMT street and certain streets through plots will be of flexible ROW will get implemented when the plots go for redevelopment with certain incentives.
The circulation shows the street leading to the riverfront and to the biodiversity edge with shared street restricted access to the vehicles. Series of NMT streets are proposed that connecting the major public spaces withing the site.These key nodes of activity along the street that leading the public space collectively provide a range of destination and outdoor recreation opportunities to be enjoyed both by tourists and residents alike.

Public Realm Guidelines 1. There shall be continuous street tree canopy and water management landscape (bio swales) along the Neighborhood primary streets. 2. Covered walkways Along the primary street, there shall be a covered 3.5m clear walkway 3. There shall be mix of building use along the primary street 4. Parking - no on street parking permitted on the main streets 5. Dedicated cycle routes (Certain key roads within the Downtown Core Planning Area will be earmarked as dedicated cycling routes )

Key learnings
This excercise required a new understanding of urban design in city planning which was broken down in stages and each part imparted new perpective doing it so. The first part invoves the site undersanding and analysis, surveying, detail plot ownership, and it physical features,case study gave the good understanding of the existing conditions in the brownfield site of the same along with i able to understand for the furture requirements of different stakeholders The next part was as part of group upon understanding of primary and secondary data analysis coiming up with the LAP (Local Area Plan) Framework for the given site which gave understanding of the possibilities of Transforming brownfield site through TOZ - Local area plan and lead to the startegy framework. This was followed by individual proposal for Urban transformation in the delineated boundary by assessing the precinct and coming up with trigger projects for the Urban transformation which gave the understanding the imporatance of public projects and priyority of its development. The final part was the detail working of design Proposal which involved the key learning from previous study and using those as a tool to achieve Framework strategy. Finally the connecting back with overall LAP (Local Area Plan) Framework and design intent of projects. This process enabled to work in large Urban Transformation of Brownfield sites.
