01 . LAKE EDGE AS A SOCIAL NODE Lake Renewal project, Bellandur

Project Type : Design Thesis University : M.arch, CEPT university Location : Bellandur lake , Bangalore Water and Urban form have always been considered as opposites, It is always looked as “either this or that”.

The vision of the project is to accommodate the lakes in the planning of the city of Bangalore giving rise to a new urban ecology .

An investigation into how Bangalore lakes can become a social node that serves as a third space a place of public realm .

Records suggest that till 1960 there were 262 water bodies in Bangalore. Today the figure has come down to 81, out of which only 34 are recognized as live lakes..

Design Question

Aim

Relationship between city & its lakes has changed over time , our need for the lake today is not what it was years ago, How can we re-establish a multifunctional use of lakes in context of today’s cities.

The urban design project aims to create a design approach which will revitalize the lake in an ecologically sensitive way and to also re-establish a multifunctional value of the Bellandur lake in the context of today’s built environment, users and nature with an intent of reconnecting the lakes to the city.

How to revive urban lakes in Bangalore using in an ecologically sensitive way .

Theoretical Premise Urban context

Context of the lake is what becomes the most important aspect of an urban lake

Social Aspect

Value is driven by the society needs and preferences from the lake. Value keeps changing based on the society involved with it

Attached Value Reviving an urban lake, re- establishing its identity is the restoration of societal connection to it , lost as a result of urbanisation

Multifunctional use value The different typology around the lake react and use the lake in different ways, these become important social factors in rejuvenating the lake. The variations give an opportunity to develop a multifunctional use value to the lake. Making it more diverse and sustainable

Zones

Understanding the typology around the lake.

A vast lake like Bellandur has innumerable edge conditions. The idea was to study each condition and to cater to the unique needs of that particular zone.

For the thesis project I have indentified and studied 7 such zones. I will be running through one of the demo areas in this portfolio.

The edge conditions of the lake largely depend on the building type and economic conditions of the adjacent civilization.

For instance, low rise homes with little private open space utilise the open area abutting the lake more efficiently that high rise buildings where it becomes sites for dumping waste & corruption

Mapping the urban context along the lake edge

Sample Zone 1

Encroachment of low rise buildings in the buffer area

There is solid waste disposal in certain areas on the site

The lack of open spaces in the low rise structures results in aprropriation of lake edge

Sample Zone 2

Encroachment of buildings

high rise

The boundary wall cuts off the connection to the lake , open spaces within the boundary

Human involvement with the lake is missing , there is solid waste and area is prone to illegal activities

Design Strategy used for Sample Zone 1 Owing to the dense built fabric of this area.

Most of the activities happen on the roads, creating congestion

congestion of road with various activities solid & wet waste - dumpyard

varies activities roads as eco channels - porous footpath irrigation pit, filtered water flow eco buffer- natural ecology with little or no human intervention

Vegetable, fruit vendors, tea stalls, kids playing. flower vendors, people gathering for leisure all takes place on the roads.

Demo Plan -1 Owing to the dense built fabric of this area. Most of the activities happen on the roads, creating congestion. The edges became a dumoing yard. The idea was to decentralise the activities and utilise the edge for this. The roads behave as eco channels & the immediate lake edge is an eco buffer.
