Swinburne architecture_India study tour 2019_The Color of Chennai

FUTURE THINKING REHOUSING CHENNAI SLUM DWELLERS Ideas towards promoting discussion around possible routes to improve the design of housing developments in Chennai for former slum dwellers. A brief report on strategies that add design value to the currently deployed construction system and development model aimed at improving construction speed. Strategies include working within the significant economic constraints while avoiding disrupting tried-and-tested procedures.

This document collates essential briefing material and design ideas gathered during a December 2019 study tour towards such an integrated design approach.

THE COLOUR OF CHENNAI Executive summary This design proposal was the outcome of a 2019 Swinburne Architecture Program travelling studio to Chennai, the capital city of the South Indian state Tamil Nadu. The study tour was led by Professor Marcus White and Canhui Chen, funded by the Australian Department of Foreign Affairs and Trade (DFAT), through the New Colombo Plan (NCP) mobility program.

The travelling studio focused on the challenges of slum clearance and relocation in Chennai. Of particular note was the slum residents’ reluctance and, in some cases, outright opposition to relocating away from their slum area to a zone where new social housing was being developed by the local government.

Throughout the tour, students attended a series of lectures and workshops offered by various stakeholders and local authorities such as experts at IIT Madras (IITM) and officials from the Tamil Nadu Slum Clearance Board. Furthermore, the students were given the opportunity to visit a number of slum areas in Chennai, as well as in-progress construction sites for relocation housing developments.

The travelling studio participants worked on ideas that could promote discussion around possible routes to improve the design of the developments they were studying. The key challenge was to suggest strategies that would avoid disrupting the current construction system and development model employed by the local contractor aimed at improving construction speed and working within the significant economic constraints.

The resulting design proposal in this ‘Colour of Chennai’ travelling studio summary has four principal aims: 1. Create a public interface that promotes local communal activities; 2. Enlarge the central courtyard to increase natural cross-ventilation, sunlight penetration and thermal comfort of the space; 3. Create a compact yet flexible interior layout which accommodates the different needs of the incoming occupants; 4. Construct a balcony and facade design that utilised local construction method and embrace cultural richness.

Ultimately, the goal is to bring to the development the translocating residents’ sense of community, optimism, social vibrancy and colourfulness that were so much in evidence within the slum area.

service cores, providing limited scope of natural airflow.

•

Building forms and facades were aesthetically unappealing, little effort was made to welcome the new residents. Repetitive modular units presented a dull impression.

•

The authority was reluctant to consider the cultural and social background of the relocated slum-dwellers. As a result, the new development was struggling to create a sense of belonging to them.

•

Building performance in terms of sustainability and energy efficiency was unsatisfactory.

Existing Condition •

A residential complex composed of three building blocks was under construction to relocate local slum-dwellers.

•

The new development was driven purely by construction speed and economic constraints.

•

They were often led by engineers only and had little input from architects, let alone forthcoming local residents.

•

The housing projects were high density, mass concrete developments, that had little access to natural light and ventilation. The central courtyard was almost blocked by

Design Objective: The primary objective was to utilise public space and public interface to integrate the site with its surroundings effectively and to foster and promote local activities. The students investigated predominant social and cultural practices of present slum-dwellers to identify key design elements. Spatial design, careful material choices and urban planning strategies were implemented in the design process to create a space that is environmentally and culturally sensitive and reflects community practices.

Pongal

Design Proposal A comprehensive design proposal was developed considering all the aspects of site features, spatial and physical configuration. Two major axes, commercial and leisure, were proposed across the site to facilitate commercial activities and promote community interaction.

Major design interventions included green spaces with organic walkways in the ground level, courtyard garden space, an amphitheater, sky bridges connecting two adjacent buildings and provision of a basketball court.

SUSTAINABILITY STUDIES: creating liveable spaces Student Team: Amy Nuccio Nicole Farnell Eddy Jameler De Leon

Design Objective:

the building block, creating an unobstructed circulation of air and ensure adequate light in the interior of individual units.

Major design considerations included the relocation of stairs and lifts, repositioning of exhaust vents and introduction of the thermal chimney to remove heat efficiently from individual units. The proposed development was analysed using digital simulation tools and the result showed vast improvement in the lighting level of the units.

Existing Interior

Greatly more liveable spaces were created through sustainability studies of the existing slum clearance high rise development. By analysing lighting levels and ventilation, healthier and brighter apartments were designed to lead to happier communities. Spatial configuration and circulation provisions were reconsidered to ensure the physical and psychological wellbeing of the people.

Environmental Simulations:

Proposed Interior

Digital simulation tools were applied to find out interior conditions in terms of lighting and ventilation. Analysis of the existing development revealed many of the units received inadequate lighting levels. Service cores, composed of lifts and stairs were identified as major obstructions while position of vents provided opportunity to re-design.

Design Proposal: A design initiative was taken to open up the central space of

Lift Relocation •

The central lift cores were identified as elements impacting lighting levels and view access across units.

•

The Lifts were relocated to the external sides of the building and positioned at opposite corners to maintain equal access for units.

•

The relocation of the lifts allowed adequate daylight in the central space of the building.

Stair Relocation •

The stairwells were identified as elements obstructing daylight and natural airflow inside the building.

•

The stairs were rotated 90 degrees, aligning to the longer facade of the building.

•

The new orientation of stairs increased central lighting and reduced view obstruction while access remained the same for all units.

Thermal Chimney •

The existing ventilation shafts and lighting wells were identified as areas that could be made more efficient with the addition of thermal chimneys.

•

Each of the current units was appointed one shaft which exposed to the external environment.

•

Each shaft was exposed at the rooftop level and unit level, causing heat to be dispersed throughout the building.

•

By enclosing the shafts and including thermal chimneys, heat could be more directly relinquished from the building.

INTERNAL LAYOUT: capturing the lifestyle of slum-dwellers Student Team: Brodie Wilkinson Tara Peters Tirth Nayak Mark Datiles

Design Objective: The internal layout was redesigned to suit the lifestyle and social practices of the relocated families. The concept was informed by re-evaluating the existing unit plan, identifying key features and issues, proposing possible alternative solutions and most importantly, gaining an understanding of the residents’ way of life to ensure a connection remained between old space & new.

Design proposal: A design proposal was developed for internal layout considering social and functional aspects of the living condition of relocated families. Social aspects included community living, religion, diversity, individualism, sense of identity and comfort. Storage capacity, security, affordability, multi-dwelling provision, and structural stability were considered as key functional aspects in the design process.

The existing apartment layout was re-evaluated in terms of spatial quality, functional arrangement and environmental conditions (light and ventilation). The new proposal considered multi-level sleeping arrangements to reduce the size of bedrooms. The living area and kitchen were combined to form a large space with an adjacent balcony.

This arrangement allowed adequate light and ventilation inside the common space. Additionally, the quantity of concrete used in construction could be reduced significantly.

Patterns

Design Objective: Traditional building elements and methods were revived through exploring sustainable facade design options. The idea of breeze blocks, conventional brick arches, culturally meaningful patterns, and murals was investigated and applied in design to achieve a living space that is culturally responsive to its dwellers.

•

Extrusion of certain spaces gives the facade a modular appearance, breaking up the monotony of plain surface.

Patterns provide building facades with unique character and identity, emphasising on local trends.

Colour •

Colour improves the facade aesthetic significantly, adding a sense of uniqueness- a practice that is highly appreciated in Indian culture.

Design Proposal: •

More vents were introduced to facilitate passive cooling through cross ventilation.

•

Adequate daylight access was achieved in the interior spaces by applying translucent (mesh) and permeable (breeze blocks) material.

•

Vibrant and cheerful colours were applied in the building facade, aiming to create an exciting living space.

•

Design options emphasised on cultural references, initiating to develop a stronger sense of ownership in the tenants.

Breeze Block Ideation •

Generalised religious and cultural symbols and shapes were developed to create a set of universal breeze blocks, to represent people from different religious backgrounds.

•

Compressed Earth Blocks were used to ensure regular temperature and efficient energy consumption.

•

Squares and rectangles represent solidity, stability, and physicality.

•

Squares and circles combined often represent heaven and earth or spiritual and material.

•

In reference to religious beliefs, specific colours were applied to the breeze blocks to achieve prosperity in life.
