kroma.

The ultimate level of development attained by an child is determined by their experiences in the first few years of their life. From a very early age, children are capable of consciously perceiving, using, and evaluating the physical environment that surrounds them.

Often a place that instills fear in children due to being an unfamiliar environment, a Kindergarten needs to have an inviting and unique appearance. So, the space was made to appear friendly without any sharp corners and was given a lively appearance by using various colours and interesting shapes which would appeal to a nervous child’s mind; a space that sparks curiosity and nurtures their creativity.

This design helped develop a better understanding of the importance of designing a building that suits its purpose and appeals to its intended users rather than a general audience. All the drawings and renders were done completely by hand in order to tap into the playfulness and creativity that i wished to incorporate into the project. kindergarten | 03

movēre The Indian population is ever-growing, this means more people are constantly moving. Public mobility spaces act as nodes for this movement; they help connect people to places across the country.

Presently, uncontrollable mobility at every part of the city has given rise to an increase in crowded spaces. These spaces are becoming hotspots for the transmission of diseases and hence caged people inside their homes.

In India, the public transportation sector indulges in transporting millions of people a day. The bus sector alone operates 170,000 buses carrying 70 million or more people every single day. How can these spaces transform? How do we change the idea of crowded public mobility areas? How do we make them work for a pandemic and post-pandemic world?

For this project, we proposed the redesign of the existing bus terminal : JBS or Jubilee Bus Station. It is a two-tier bus terminal located in Hyderabad, Telangana. Located in the heart of the city and teeming with people on a daily basis, it is an important area that needs to be made serviceable for a post-pandemic world.

Jubilee Bus Stand (JBS), is located in the heart of Secunderabad, Telangana. It is one of the two main bus stations for buses leaving Hyderabad city, the other being MGBS. It is owned by the state run bus transport corporation, TSRTC. It is 2 km from a Railway Station and 800m from a metro station. There are about 540 bus services daily to various parts of Telangana, Andhra Pradesh, Karnataka and other neighboring states.

site surroundings SITE ANALYSIS A thorough analysis of the site and it’s existing elements revealed various problems we would have to fix through our design interventions. The main problems were the circulation, which created a lot of crowded areas and the parking, which was located too far away from the bus station.

vehicular movement bus terminal | 11

FORM EVOLUTION

CIRCULATION In the present bus terminus, every passenger has to follow the same linear path to reach their bays, which creates chaos and crowded situations. To solve this circulation problem, a radial circulation was planned. This is the circulation that would result in the least crowded spots and lead to a peaceful, healthier and safer transit experience

present circulation 12 | movēre

proposed circulation path

The roof is large and continuous, with mesh framework and openings that allow North light to enter.

The waffle roof was made to give a sense of direction to the users. The outward radial path guides them to their respective terminals without experiencing close contact with other users.

This waffle element provides some enclosure to the structure and gives a sense of unity by merging with the waffle roof.

The stalactite-like columns support the massive roof and blend into the ground seamlessly.

The no-contact entrances at the West lead outwards towards the bus bay, this makes the circulation hassle-free. The administration block is in the North and the cloak room is on the South.

The parking is underground so that people do not have to park their vehicles far away and walk to the station. This was a major problem in the existing design.

comunità Community is central to human experience. The goal for this project was to create a place of gathering, a space that allows vibrant and joyful experiences and provides support of some kind—be it relief from hectic daily life, meeting like-minded people, finding new interests, delving deeper into existing interests or by simply being a place to spend some time.

The spaces can cover a wide range of facilities, forming part of the ‘hard’ social infrastructure that supports community wellbeing in the city. Services and activities developed and delivered from these assets help bring people together, and improve and strengthen neighbourhoods, community resilience and community safety. community centre | 15

net-zero?

As population continuously increases, urban areas and businesses will continue to grow, bringing growth in construction of large buildings that continue to negatively impact the environment. It was announced at the COP26 by India that the country would cut down emissions to net zero by 2070.In addition to this goal, The IGBC had also set the target of achieving 10 billion sq ft of green building base in the country by 2022.

So, we partnered with Savvy Group to design a green office building, which can help add to the sustainability goals of India. We focused on major sustainability goals such as water and energy efficiency, scalability, market potential, resilience, health and well-being and affordability, The project brief provided by Savvy calls for the development of a 15-storey commercial complex designed to follow the principles of sustainable green buildings, comprising modern, flexible and efficient office spaces.

For this project we worked with a project partner who gave us various requirements for the office building they were looking for. We engaged with them frequently and designed the building as per their needs. We also partnered with industry partners who helped us plan and choose the materials and systems of the building. Overall, it was a very realistic work experience.

The proposed building has 15-storeys and an average of 5,040 users a day. Consequently, It was incredibly challenging to attempt make it net-zero due to the huge population occupying it, the height, and the taxing water and energy requirements for such a large office building

LOUVRE DESIGN A louvered facade system that was optimal for our building and its context was designed.

We tried multiple iterations and analysed their respective simulations.

13 horizontal louvres on South side, spaced 250 mm from each other and extruding 125 mm from the walls The other sides used a combination of dense horizontal and vertical louvres which were tilted 22° towards the building

NIGHT FLUSH VENTILATION

200 mm PT Slab

Night-Flush ventilation is a strategy used to cool down the building structure via lower external air temperatures at night. This strategy employs the building’s thermal mass as an intermediate storage medium, allowing the structure to absorb the heat built up during the day and to flush it away during the night.
