The use of collibri in the design tools was extremely handy to experiment and understand the best design iteration in terms of shape, window sizes, core positions, wall and window U values, which best fit the location of the building and provide the designer with the lowest Energy Use Index to move forward with an informed design decision for the proposal. The proposal is then tested for embodied carbon in Structural, Facade and architectural elements and MEP, to understand and bring out the best solution the promotes greater environmental good and occupant comfort and wellbeing.

GUIDANCE: Ar. PAULA CADIMA Ar. SIMOS YANNAS Ar. JORGE RODRIGUZ Ar. JOANA GONCALVES

Bioclimatic retrofit of a high-rise building targetting towards net-zero carbon emissions deals with a great challenge of achieving comfort for not only the occupants on the interiors, but also for the atmosphere struggling to find its way through climate change. Explorations of the building depth, its materiality, its potential and it’s performance in the given context having a stark variation towards comfort levels raises the need for a retrofit adressing climate considerate actions.

3 PROFESSIONAL CAREER | INDIA 1. SPACE MATRIX, BANGALORE Jan 2020- July 2021 2. MALIK ARCHITECTURE, MUMBAI June 2019- Jan 2020 PROJECTS: RADISSON RESORT, LONAVALA IIITDM, KURNOOL DNR RESIDENCES, BANGALORE GUIDANCE: Ar. KAMAL MALIK Ar. KETAN CHAUDHURY Ar. RAGHAVENDRA HEGDE Ar. KAVANA MAHADESH The experience of Space Matrix and Malik Architecture in India, has been the stepping stone towards Architectural detail. Obtaining a holistic experience of dealing with project from its ealry stage concepts unto construction detials has provided great insight in working with teams with a varied skillset. Churning the creative aspects of design alongside technical detailing provided were aspects I trained myself with to widen my knowledge further.

RADISSON RESORT Lonavala, India

Radissson Spa and Resort, Lonavala is a project that has completed construction today and my contibution towards this project was during the design development stages through 3D modelling and construction drawings of the common interior spaces such as the restaurant and bar. The homely, yet raw local cultural vibe of the space brings out the essence of the design. The material palette of exposed stone, concrete and wood was chosen in alignment with the exteriors and theme of the spaces.

The Indian Institute of Information Technology, Design and Manufacturing, in Kurnool is a Government aided project on a 40 acre site. It receives a LEED certification based on pre design reports. I was involved in the production of tender and construction drawings such as the plans, sections and elevations along with details such as the facades, staircases, basements, skylights, compounding, etc.,

Landscape that integrates the campus as a community

Plaza following the natural countours on site

Landscape interaction with the built environment

The vast land parcel is strategically planned allowing a full fledged residential campus to have circulation along the site through different blocks which are zoned on the masterplan for easy access. The director’s bunglow is placed at the central portion of the site on the peak of the countours allowing a strategic view to all sides of the campus. The challenge of working along with an ever changing coutour site, trickles the mind to produce the most efficient design and hence allowing administration and seminar hall to be a unit undistrurbed from the rest of teh campus, which was my personal score of work in the course of the project.

The clubhouse is a centre for recreation with amenities required for users of all age groups. The connect between the spaces along the three towers allows an inside-out space bringing in the natural landscape to the interiors of the building.

Facade design details were explored further with vertical and horizontal elements, along with change in materials as proposals towards specialized and iterative design approach..

PUSHPA DEVANATHAN Ar. RAJSHEKHAR RAO Ar. LAVANYA VIKRAM Ar. KUSUM SINGH The introduction to Architectural Design and creative exploration, beginning from a cottage to a masterplan, was dealt with, over the 5-years of the rigorous course. Learning the construction details, structural design, fixtures and further more integrated with architectural design was a the first foot into the industry.

TURNOVER Bangalore, India

SEZ development influences the urban fabric of the vicinity creating a ripple effect that dictates the surrounding development and promote urbanization. The development of the city inspires the design to create a heirarchy in terms of visual charecter which creates an edge to the road forming an inviting approach to the city as it adds to the formation of a gateway between two metropolitan cities with rapid urban development on either fronts. The design is an attempt to rejuvenate what the land has lost and create vertical urban green terraces tracing back to its history of the surroundings. The mixed used development on site has floor plates with a twist pattern that cascade green balconies as the building stands tall. The landscaping on site is a response to the privacy for the two user groups for recreational purposes which also strives to give back a cleaner atmosphere to its surrounding.

The pedestrian plaza provides grandeur in design which allows one to admire building with its twists and cascading landscape. This entrace plaza provides access to the podium that consists of recreational activities.

The indivitual floor balconies are divided by trellis separations per room and achieve views to the lake in the vicinity and its adjecent building. It provides additional recreational facities to the users of the hotel.

COLLOQIAL DEED Mysore, India

The tourism hub inteneded to be a icon of the arts and culture of Karnataka’s rich heritage has taken inspiration from the vernacular forms of architecture into the modern day style of design as factors driving the fore of design. Since the design is guided and crafted for 3 user groups, the design is originally dictated by elemts such that, a passerby at the site visually connects with the freestanding cantelever exhibition centre which is elevated over the ground. This forms a user to understand the interpretation of the culture of the state. Once intrigued, a visitor/tourist, may take a guided 2 day itinerary around the site engaging in activities in and around the site for a cultural tour of the state in a compised arrangement. Further, students willing to undergo vocational training achieve the educational aspects and inculcate the arts of the rich heritage and showcase them in the areas on site means for showcasing their skills and talent.

The site is located in the route towards Hassan from Mysore along the back waters of KRS. The site provide emplyment opportunity to the residents in the surrounding to enrich the rich culture. The macro level site analysis provides climatic impacts which dictate the orientation and materials of the buildings. The aim of the project is to achieve a single stop destination for students, tourists and labourers with a variety of skills and develop community culture.

Features on the site that allow a tourist/visitor to achieve the complete essence of the project’s intention is through the bridge that gradually meanders through the site allowing a user to visually connect with heritage aspect of vernacular designing that has been converted to modern architecture through buildings. The totem poles behaving as signages replicate the Channapatna toy making culture. The experience centre allows one to understand the history and envision the future of the state of Karnataka in its elevator experience. Aspects in building design and orientation also replicate the state’s culture The master plan is arranged such, that an entrance to the auditorium on the rear end and the amphitheatere are accessible separately and maintained privately. The journey through the site with its itinararies allow a user to achieve a wholesome and holistic experience with engaging spaces such as the central gathering area that consists of interactive installations for users of all age groups.
