Resurrection of dumpyard

Role : Student designer

Studio : B.Arch Graduation thesis project

The centre for creative use of waste is the resurrection of an existing dumpyard on the foot of the only marshland of Chennai, India. The proposal houses activities, flexible exhibition galleries and spaces which also acts as an example of alternative construction materials. The existing dumpyard which is inactive would be treated, cleared and part of it is used to make a mound, retaining the identity of the space. The centre’s narrative is to promote “Reduce, Re-use and Up-cycle”. As people walk through the spaces, they have to choose between “Stairway to heaven” and “Highway to hell”. Highway to hell exhibition cuts through the mound with space depicting dystopian Chennai while the “Stairway to heaven” depicts utopian Chennai instigating people to think their consumption patterns. A watch tower looking over the vast marshland turned dumpyard intiates conversation on preservation and conscious consumption. The centre holds a prototype of weekly market and a segregation unit handling dry waste for 2km radius. c

Regenerating streets Role : Intern Architect

Studio : Triple O Studio, Chennai

This was a real time streets redevelopement project of KCT college, Coimbatore, India. Me and my co-intern worked on the initial study understanding the culture and users of the college premises. We identified the street being a catalyst for initiating conversations, breaking hierarchy between tutors, senior and junior students. The street acts as both place and link between destinations. It is the PUBLIC SPACES on campus that alumni best remember, and it is these places that play a strong role in attracting new students. We conducted surveys to understand the usage of the streets both as a link and a space. The survey suggested that the majority of the students - day scholars, found it difficult to reach destinations by walk. A bicycle sharing system with pod locations were identified and proposed. The main hot spots - Academic plaza, game floor and the plaza were identified and designed for better placemaking. The first phase of project was enhancing the streets making it pedestrian friendly. I was solely responsible for this first phase and site supervision.

Funnel Stool

Role : Graduate Student Designer

Studio : The way we live - Understanding the home, CEPT

The funnel stool is a project aimed towards wood joinery exploration. The stool is inspired by Nakashima’s furniture and elegant wooden joinery details. Nakashima’s main focus was on good craftmanship, conscious decision of details and joinery. Building on the ideology, funnel stool expressed the same by evident visible joints of the seat. I was curious to work with local wood and chose mango wood for the seat. Mango wood is harvested from locally grown species, the wood is kaleidoscopic in colors because of spalting which instigates curiosity. The seat is put together by three pieces of wood joined by a open tenon and mortise joint, further the form of funnel is achieved by chiseling the wood out. The legs are fixed with tenon wedge joinery without usage of any adhesives. The stool is 1 of 10 shortlisted furniture to be produced at National Institute of Design for Nakashima & NID : A celebration in wood, 2017.

Step Stool

Role : Graduate Student Designer

Studio : Studio project, CEPT

This was a 2 week time problem executed in collaboration with fellow graduate designer from my cohort. The brief for the class was to propose furniture for the upcoming central library of the campus. We studied the requirements and functionis of the current library followed by understanding the architecture and spatial character of the upcoming library. We chose to design a multi purpose stool. The corridor space being narrow, a stool that acts both as a seating to skim through books while reading and a step stool to access the books on higher shelves was proposed and designed. Ideation led to two options, one was a stepped sit-stand stool, second was a tiltable step stool. We made quick mock-ups to understand the scale and functionality and chose the second one as it was very compact and easy to maneuver between the carrels/corridors of the library. We designed a single wholesome piece and explored steam bending steam beech. Using pressure cooker to steam as make shift method and after three attempts, we were successful at steam bending in the small scale.

SEWA | Storage systems

Role : Graduate Student Designer

Studio : Design at work, CEPT

The studio based course “Design at work” was to understand workspace and design a furniture for efficient working at the workplace. The class studied workspace of SEWA, a trade union organisation of economically challenged, self-employed women workers of Ahmedabad, India. The existing condition of the workspace was disorganised and chaotic. All the working and archived files were spread across the workspace inclusive of working desks affecting the efficiency of the employees. I took the organisation and storage systems as the point of intervention and proposed a storage system. My design proposal was a modular storage system, made of bent sheet metal which is stable in structure, has long life span and is economical compared to plywood. Most of the existing sheet metal storage systems available in the markets has sharp edges, I designed a sandwiched sheet metal panel with flinched threaded recessions for easy and cleaner bolted joints. The storage is flat packable and thus reduces transportation difficulties too. I made a part prototype to experiment and refine the joints.

Systems design | Banking

Role : Graduate Student Designer

Studio : Systemic design - Furniture for institutions, CEPT

The studio introduced “Systems thinking” approach and application to design. The brief was to understand banking and propose an intervention to solve any issue faced by any user in the system. Research and studying the systems of banks led to understanding the importance of the relationship between the bank and customer. This led to revelation that bank is similar to an airline, where the customer is considered a vital element of the system and bank is one of the many “social levelers”. With the world moving faster towards digitalisation, banking industry aswell is keeping pace with the rapid technological advancement. Customers are identified to struggle with this rapid transition. Though the phone and mobile banking is accessed, a majority of the customers feel under confident to carry out digital transactions. I was interested in catering to this target group. The intervention is aimed at making the transition from manual to digital transactions easier for the customers by empowering them with knowledge, building confidence and accomplish the transactions with comfort.

06 The traditional, current spatial design of the bank accomodates for live interactions to carry out transactions. In the first phase, the spaces are divided into 5 types based on the level of hesitance of the customer. Self banking ATM, with separate access from outside for the confident customers, self-banking kiosk right at the entance for little hesistant customers. An interactive banking space with mock transactions for the customers willing to try. A physical live counter for banking with an official, and a private space for customers to dicuss and transact in private. To aid this I designed and prototyped a modular furniture system to acts as a space maker, depending on the neccessity instead of creating physical partitions, thus easier to transit to phase two, three, four and the last phase with zero dependance on bank officials. The furniture system is flat packable and assembled on site. For the customers to feel welcome and relatable to the bank, the fabric and patterns are customised according to the locality and its identity.

The big data cruncher Role : Interior Designer

Studio : Spacematrix, India

The client was a young fast-growing IT company in need of extending their physical workspace. I single handledly worked on the design development, presentations, client management, preparing technical construction drawings, verifying bill of quantities documents, furniture dockets, coordinating with vendors and supervising execution at site under the guidance of our Lead designer. The design was conceptualised with openness, kept clean and simple in terms of planning as well as the visual quality. We decided to go with open exposed ceiling to alleviate openess and increase volume of the space. We brought in the natural elements and attempted to promote collaboration within the office and across continents, through flexible use of a large designated space for training and group activities. The meeting rooms are color coded with company’s brand palette visible from the open office. This sets the subtle minimal backset for the office maintaining the identity.

My colleague and I worked together on design development, presentations, preparing technical construction drawings, bill of quantities documents, furniture dockets, coordinating with vendors and supervising execution at site. The intent of the project was to create model apartment for customers to visit and understand the space before investing. Thus, we designed an executed the model apartment to be fully functioning and ready to inhabit. The 3 bedroom show-flat has been conceptualized and executed as cozy and opulent house that celebrates luxury and plushness. The shell is wrapped with wood created assorted compositions, transforming from sleek elegant lines to chic surfaces. Interplay of balanced use of bold colors and warm lighting form soothing visual compositions. Customized furniture, curated lights, accessories and a touch of green plants take the story forward making it a vibrant space. The floral art-prints compliments and accentuates the overall cohesive design language.

Passing the baton Role : Workshop instructor

workshop : Collaboration with Haripriya & Science Gallery, Dublin

Responsibility : Research | Systems thinking | Workshop development | Workshop instructor Tools : Canva

I had an opportunity to conduct a workshop on food, sustainability and systems thinking packaged as “Passing the baton” at Youth symposium 2021 : Boredom rebellion, by Science Gallery, Dublin. The workshop was intended to make participants aware of the cultural, historical, contextual and emotional nature of food in order to understand its deeper connection to the individuals. The vision was to create a dinner table for the attendees where ideas, memories and thoughts can be expressed and listened, where people can bond over their shared experiences and build a community. Using systems thinking as a tool, participants recalled, reflected and documented food memories that are personally significant. These narratives would be analyzed to create a resource bank that can be passed on to the future - as a baton. Avocado was used as a relatable example to introduce systems thinking.

HA-TA

Role : Architect | Structural design specialist

competition : Yoga on the cliff | Bee breaders

The brief

This is a modified competition entry for a barrier free “Yoga house on cliff” designed with energy efficient measures for Vale De Moses, Portugal. My responsibilites encompassed being an architect, structural and design specialist in collaboration with fellow architects, a Sustainability specialist and an Energy consultant.

SKY AIR

EARTH

WATER

FIRE

Ha-Ta is designed with a concept of open-ness and earthy nature. It encourages an occupant to feel a sense of belonging and gratitude for life on earth. Ha-Ta has achieved this by adopting to the five (5) elements of life or the ‘Pancha Bhuta’ as it is said in Sanskrit (one of the oldest languages spoken and written in scriptures. It is also considered as the ‘spiritual capital’) Ha-Ta touches upon all these elements and beautifully merges them in one location as: Earth - Site slopes incorporated with Ha-Ta and contour on the east is beautifully integrated as an earth berm and given access to people to take a long night stroll. Air - Air is given importance and the form of the building is designed to always let in wind through all directions by a hexagonal design . This form does not obstruct wind and hence a basic square or a rectangular form has been molded to a hexagonal yogic space. The main yoga space has been raised one level above for free-flowing air to brush through the human skin and make us feel comfortable and warm. Sky - Raising the building a level higher than placing it on the ground is to allow the human eye to search more for the blue sky and the tall trees. This enhances peace of mind and releases happy hormones inside the body like dopamine and serotonin. Water - Ha-Ta can be accessed by climbing through the ramp or walking through the beautiful and elegant Zen garden designed in front of the building. It hosts pebbles, stones, water flowing, miniature water falls to induce the sound of water. This is called ‘White noise’ and we can let go of our thoughts and let the noise wash over us! Fire - Ha-Ta is designed to be exposed to optimum amount of radiation from the sun. It smartly cuts down most of the direct radiation through the South and lets in diffuse radiation with excellent daylight through the north side that has a large, glazed opening area just to focus on daylight and feel the warmth.

10 Oleiros

The site is located at 39°58’58.6”N 7°55’03.6”W and has the Mediterranean climate. The summers are hot and dry, and the temperature is mild in the winter. The average annual temperature for Oleiros is 21° degrees and there is about 336 mm of rain in a year. It is dry for 236 days a year with an average humidity of 72% and an UV-index of 5 Castelo Branco’s climate file was used for the climate analysis as it was the nearest weather station available.

High Direct Normal - June to Sept Low Direct Normal – Oct to May High Diffuse Radiation – Apr to May Low Diffuse Radiation – June to March Max. radiation - S, SW, SE, W & E Min. radiation - N, NE, NW

DESIGN STRATEGY

1. Cross-ventilation - with operable windows considering different thermal requirements for summer and winter 2. Thermal Comfort - Zen garden is designed and created with pockets of water bodies to add humidity for summer thermal comfort as occupancy in summer is expected to be higher.

1. Southern façade - Shading required during summer 2. Northern façade - Diffused daylight as it has no direct radiation component 3. Renewable Energy - Rooftop Solar PV panels oriented 39.5deg (same as latitude of Oleiros) toward South to maximizesolar energy 4. Embodied Energy - Usage of vernacular building materials to reduce embodied energy

Windows are operable on all facades of the building based on the following: 1. S, E - Direct radiation is evident from sun path & global horizontal but no wind flow from these directions. Hence possibility of high temperature winds are cut off, making the design passively cool. 2. E- Direct radiation is evident but no wind flow from East direction. Nearby slope on the eastern side prevents the building to experience morning healthy sun and moderate air flow. So, design is raised structurally to a higher level and Yoga space housed on first floor for optimum exposure to radiation and views. 3. W- Direct radiation is evident from west side but presence of trees are incorporated in the design and does not favor cutting down the trees. Evening sun and high temperature wind flow from the west is cut down by trees.

Prevalent wind direction - W, N, NW Moderate wind direction - S, NE and N Wind speed 7m/s

Adaptive Comfort & Outdoor Universal thermal Climate Index

Summers - Hot 12 pm - 6 pm (Uncomfortable) Winters - Cold (Uncomfortable)

10 HA-TA’s hexagonal layout ideology

1. Elongated site leading to unfavourable orientation of E-W. 2. Adjacent slope contour advantage used with earth berm for passive heating and cooling by raising the structure by 4m. 3. Favourable multi-oriented facades disabling long sun exposure hours on a single wall - Advantage of harvesting wind based on wind direction. 4. Compact space planning considering unobstructed yoga space for 38 + 1 users - Multidirectional view points towards mountains and valleys for enhanced mental health. Roof Plan

The Baseline case was considered to be a conventional building with Solar PV sizing typical features without the incorporation of energy efficiency meaTotal EUI = 34 kWh/m²yr = 5304kWh/yr (approx.) sures. The Energy Use Intensity for the baseline case was 60kWh/m2.yr. A 1kWh of solar PV serves = 1400kWh/ yr series of elimination parametrics and sensitivity analysis were done Solar PV sizing necessary = 5304/1400 = ~3.8kWh PV 1 kWh consumption needs 110 Sq.ft. of rooftop area to understand the factors that affect energy use to the maximum. 3.8kWh needs = ~418 to 500 Sq.ft. rooftop area Based on this, the above series of parametric runs were finalised and collaborated for concise results schematically.

INDOOR AIR QUALITY features:

Daylighting features 1. Window to Wall Ratio of 40% on all sides except North 2. North façade, facing diffused solar radiation given clerestorey openings to facilitate more daylight, Window Glazing is proposed with low VLT of 40% considering high WWR is sufficient for daylighting 3. The space has excellent daylighting with 100% of the space daylight >300lux throughout the year.

Annual Solar Exposure = 2.2% Percentage of analysis points ≥ 1,000 lux for ≥ 1000 hours per year

Spatial Daylight Autonomy = 100% Percentage of analysis points ≥ 300 lux for ≥ 50% of the hours

1. Indoor air quality monitors are proposed for the building at 6 strategic locations- at the centre of each facade at human height of 5 feet erected on the walls. 2.
