• Commercial not a preferred use

• Better to simplify the uses based on economic study

“Streets (other than major highways) proposed for predominately industrial areas which will be used for heavy truck traffic or truck parking may be constructed according to Type A secondary highway width and standardswith approval of the engineering and survey services director, roads director, and the planning director”

New industrial roads will be required to have a 90’ ROW and potentially existing roads will also need to be upgraded.

Water demand is estimated to be 100 acre-feet per year, which includes 54 AF for domestic use by employees and 44 AF for landscape irrigation.

GEARY TRIANGLE

Richmond District, San Francisco

RICHMOND DISTRICT

The Richmond District in San Francisco is a diverse and predominantly residential development with two major city parks bordering it. The district also has various retail and commercial activities along some major streets.

92% of the district parcels allocated to residential plots.

Existing CONTEXT

A major point of critique is that the district edges, where it interacts with the city and parks, is highly acontextual to its immediate surrounding and uses. For example, the blocks that face the Golden Gate Park are as mono-functional in use and as low/dense as a midneighborhood block, almost completely ignoring the presence of a major city park in front.

The same applies to the presence of schools, other parks, the oceanfront, the Presidio Boulevard, or the university and Central SF.

Defined park edges and tree cover

Urban MORPHOLOGY

Almost all parcels allow 4 stories, but only 9% are 3 or 4 stories. Multiple zoning and building regulations are applied here, the resultant land use indicates that the majority (92%) of the blocks are monofunctional residential plots, almost as residue after the main commercial district areas.

Land Use Land Use based on Street Type

GEOGRAPHY

The sheet flow direction along the Geary Boulevard drains the storm water into Sutro Heights. Using the topography and drainage pattern can help to channel the storm water through green infrastructure. The Geary triangle needs green infrastructure connection to the Land’s end and Sutro Heights.

Sheet flow direction Connecting the parks through green infrastructure

MOBILITY

The historic map of 1880 San Francisco street morphology is an evidence for the use of street cars which could be a reason for this triangular intersection. Richmond provides opportunities for east-west and north-south connections, while improved connections to Richmond could generate improved accessibility to green spaces and ocean beach. The Geary triangle witness a higher collision rate which demands a redesign of node into a safe, accessible transit destination to the residents and floating population.

WEAVING INTERBAY

1.5% population growth in SEATTLE

Before the dramatic regrading of Seattle, Interbay was a coastal zone of tidal flats, wetlands and coastal forest. The geography and ecology of Interbay in Seattle has heavily been altered through regrading anvvd landfills. Despite the extensive engineering, Interbay is still at the risk of liquefaction from earthquakes and the effects of sea level rise. Seattle is a fast growing city with a 1.5% year-on-year growth in population which is leading to densification of the Downtown. Interbay in Seattle is a land engineered with regraded landfills and is known for fishing, Seattle armory and industies. Currently, Interbay provides around 6000 jobs through commercial and industrial establishments but fails to house the blue collar workers with the mandatory housing amendment. Weaving the urban with green infrastructure

Interbay - Site context

Interbay ranks second in accommodating local industries and commercial establishments when compared with other industrial areas in Seattle. These establishments generate a $3500 million dollar revenue per annum and this proves the value of the land and jobs created in Interbay. The growing 2.8% year-on-year population in Interbay needs vibrant programs to enhance the work life balance in the district.

Conceptualizing the URBAN FRAMEWORK

The agenda of the proposal is to integrate urban typologies with natural infrastructures. The topography defines the edge, and the landscape integrates the Interbay from north to south. The hydrology map reveals the flow pattern of stormwater and sewage drained through the landscape. Walkability and bike riding is enhanced by displacing the grid-iron pattern and replacing it with topographic connections. The density of sites is increased by introducing diverse programs associated with the existing industries.

The scope for establishing the link between the education, impacts of industries and research development could only be brought by finding their position with regard to each other. Architecture always has a significant role in contemplating and creating the learning spaces and the intent will be achieving the same in inclusion with the environment and sustainable aspects.

Need for TYPOLOGY ?

The ongoing conflict between ‘’academic rigor” and “practice based” knowledge is not withstanding, great strides have been taken more recently towards better understanding and fostering more conducive conditions for education to happen.

PROGRAM INTEGRATION

The role of architecture is finding the niche for both the entities in specific and plan them in a manner such that they exist together. Innovative handling of these entities and integrating them with context will be the role of design approach.

The industries are entities which are found to be in a crisis especially in case of manufacturing sector. Technical education system lags in competing with the globalization standards with regard to the generation of skilled labors and research scholars.

The land-use pattern of the GIDC [Gujarat Industrial Development Corporation, Ahmedabad] is classified as industrial-use category.

Site | GIDC AHMEDABAD

The manufacture industries in specific get developed where they get their resources and infrastructure from the government. Such industries are developed along the SEZ’s where they almost utilize the resources and it is significantly found in Tier 2 category of SMART CITIES. Identifying such SEZ’s and their connectivity with the city will be the first criteria of site selection. Mapping the inter relationships of existing industries and the other institutions around that area and suggesting the typology with respect to the context will be appropriate design response.

GIDC | Ahmedabad SITE ANALYSIS

Promoting mixed land use in area based developments–planning for ‘unplanned areas’ containing a range of compatible activities and land uses close to one another in order to make land use more efficient. Cultivating the need for the program within the context and responding to them through pragmatic analysis of the same. Preserving and developing open spaces.

Approach to site

Master-plan STRATEGIES

From site analysis, an inference for the programmatic zoning is developed. And based on the integration of the three different programs, the placement of the typologies are formulated.

Through site study and series of pragmatic approach, master plan is been evolved. Developing approach access points from the influx points. Retaining the northern industrial periphery and creating a buffer with the metro depot.

The process of weaving the possibilities of each typology in terms , vehicular access and industrial service needs maps the intersperse of activities within the site. Iterating the probabilities of orientation of the built form, connection between the typologies and security aspects of the industries.

Programmatic design EVOLUTION

The idea of segregating as components and clubbing it in as part programs is to bring the collaboration process part of the built. The spaces that bridge between these components act as pause points to enhance activities of a campus.

Facade facing the industries establish a connection and gives access to the tool room

Connection between institution and research laboratories area

The institution block handles the program of bringing in the feasibility of industries with the technical education. This is programmed in a manner it caters to the needs of a future technical education and attracts public attention in the city and changes the perception of industries in cities. The research typology’s significance is to be the connect between the institution and the industry. Taking this into consideration, the most often accessed tool room will be part of this block in the ground level and the institutions connect with labs will be in the upper level. A new industrial working model, while the manufacturing and the production happening at the ground level, light machinery process are carried out in the upper level accompanied by training programs creating an industrial interface.

INFLUENTIAL TIME-LINE

Retteri lake

Origin of the water

Direction of the flow

Duration 6 Weeks

1970’s

The Grand South Trunk road was laid across the retteri since it was the only connection to the north western part from the chennai city.

2004 Drought

The lake faces dry period where the lake is completely dry, encouraging people to encroach its inundation plain.

2013

Economical Development along the boundaries of the lake timber and small scale industries are developed. Major shift in land use pattern leads to the overall economical development

Retteri is an intermediate lake which does not depend on rain for water and depends on the surrounding water bodies. Adding to that, the urban development along the north of Chennai had gone beyond its limit and this is the only intermediate lake at the verge of drying out in the Kosasthaliyar river basin.

2015 Chennai floods

The outlets play a major role in preventing the flooding of the encroached inundation plains, by taking out the excess water through them.

Approach to URBAN WATER SUSTAINABILITY

The urbanization of cities around the world has given us great cities but, the ecology of the suburbs is experiencing a severe risk. The ecology had collapsed due to inhuman interventions in nature and specially with the hydrological system of the city.

Retteri lake DESIGN PROPOSAL

The urban road network dominates the cities fabric. The emotional connect to the water bodies of the city has vanished long back when the navigation and lake dependency got ceased.

The proposal involves the concept of 3E’s and based on the study and inferences, 7 zones has been identified. The design approach will be multifaceted changing the perception of water bodies considering the issues in city planning, infrastructure, water literacy and management.

“ When we walk , we think, We contemplate and thereby experience the soul beauty of the nature.”

1. To increase the Water Quantity [ Check - Dam for the farm lands ] 5. Pavilion for the Public and Lake [For the upcoming recreation proposal]

4. The Lake Conservation Centre [ The hierarchy of the 3E’s is handled through the intersection of both functional and public domain of the conservation center.]

2. Cars ‘Go’ above us [Highway above, pedestrian below]

3. The Main Bund Portal [The landscaped bund acts as a pedestrian zone]

6. Pedestrian Rings [To address the immediate precincts of the streets with water body and encourage fishing in the shallow regions]

Section along THE BRIDGE

The intervention of bridge across the lake will join the two divided parts of the lake together. The connecting bridge will be having vehicular transportation above and pedestrian access below. Bringing in an ecological sustanance within the water body.

The pedestrian rings act as a floating pavilion for fishing, recreation and environmentally sustainable for shallow water plants and fishes.

Ecology

The ecosystem of the lake is conserved by establishing a establishing a elevated connection for highways. Nodes for activity is made at the junctions and also under the bridge.

Emotion of Society

The sense of belonging towards the lake is incorporated into the design by facilitating experiential spots.

Economics

The economy of the neighborhood community is enhanced with the help of NCPL at the source of the lake, to draw the attention of the community towards the lake and bring in commerce.

Section along PEDESTRIAN RINGS

The pedestrian rings act as a floating pavilion for fishing, recreation and environmentally sustainable for shallow water plants and fishes. At regular intervals culverts are fixed to make water flow back and forth. The condition of the lake will be in view of the public and taking care of their water bodies will become the responsibility of the public through time.

Inculcating

WATER LITERACY

IN URBAN CONTEXT

An approach that incubates and inculcates the idea of co-existence should be the intervention. This will bring in belongingness and water literacy. So, that the community would take care of the water bodies.

TRANSIT SHELTER

Indian Green Building Competition

Schematic Approach - Prototype

Shelter for SHELTER SHAPERS

The construction labors have an integral part in the industry. Shaping shelter for the shelter shapers should be a primary concern for the construction industry. A resilient shelter which could bear all the outcomes of the nature should be adopted in the shelter since construction labors will always be in movement for their next workplace. Such shelter should work on sustainable methods to get adapted to the context.

MATERIALITY

for green – transit shelter is defined by the use of construction waste available and modular form-work system which integrates portability and sustainability of the shelter.

Making Shelter and MATERIALITY

The process of construction wastes a huge resource which are dumped as landfills. Instead breaking the method of waste disposal and combining the proper construction waste materials can produce valuable building elements which is beneficial for investor.

The step - by - step method of assembling the green - shelter will also be based on the property of the material. The heavier construction material will be forming the base and the lighter materials will be composing the structure to make it flexible enough to dismantle it.

STEP 1

Sculpting an URBAN LIVING

The site has a strong relationship with the major landmarks & green spaces. Views from the site towards the Governor’s palace raj bhavan complex by the south & the kowdiar palace by the north.

The units lying above the adjacent neighboring buildings take advantage of the views from the site and the units lying below overlooks the park and ensures a strong integrated community. The kitchen garden is plugged between the units creates micro community and enhances the interaction between units, which also acts a visual buffer

The site is sandwiched between two high rise buildings restricting the views & the light into the site. The irregular site profile offers a challenging design footprint on the ground after leaving a 6m drive way around.

Densifying the ground plane offers a very minimal footprint as it goes higher due to the set back regulations creates an interesting skyline but eventually minimizes the views from the site and fails to create community

By inverting the skyline upside down creates large community gathering on the ground plane and gives a relief from the existing urban fabric.

“The rain forest, creating an experiential skyline through the spaces”

Process of sculpting THE SPACES

1. Embracing the site profile by allowing the design footprint to evolve along the perimeter way around.

2. Creating a landmark building right at the entrance which anchors the site at the edge and creates an strong image-ability

The design explores the possibilities of bringing in social sustainability and increasing the open space ratio per individual. The monumental voids give space for the tall trees to grow and change the attitude of residents over spaces.

The development is a 16-story building with 2 basements. The project accommodates around 81 units including all amenities. A residence with an identity rooted to its context and a lost experience in the current world of urbanization.

3. The 12m x12m grid mass conceding one unit per floor maximizes the views

4. The masses are lifted to maximize the view on either sides, over-powering the high-rise building adjacent to the site

5. View towards the rear side of the site

6. The mass floating at the lower level achieves the view through the low lying building at the adjacent site

7. Maximizing the view towards the north

8. Creating an interactive community spaces at various levels
