Cultural Complex Design, Madurai Cultural Complex design is an individual project during the sixth semester of college. The objective was to design a centre in culturally rich Madurai to exhibit and develop the traditional art forms. The project includes an auditorium, library and a school teaching various traditional arts.
The core idea was to create a space with minimum visual interference, a privilege very few buildings have today. The vista could be enjoyed seamlessly without the interference of other structures. The important structures are the Auditorium, the library and the Open air theatre. The design had to cater to a vast number of performance arts in South India which required indoor as well as outdoor exhibition spaces. Supervisor: Prof. S.Subashini email: ssarch@tce.edu

Cultural Complex Design The site is located at the historical city Madurai. Madurai which was one of the oldest and most beautiful cities in the world is now a mere shadow of itself. Visual pollution throughout the years have affected the pleasant views which it used to flaunt.

Cultural Complex Design, Auditorium Design The auditorium would be predominantly used to stage plays, classical dances and concerts. The design is based on the fact that the average temperature below 3m from ground level close to the average temperature of the region thoughout the year. Located in a hot climate, any small change in temperature can reduce the energy required for the cooling of this large structure. In order to reduce the cooling energy, the auditorium was designed to descend below ground level.

The southern facade of the auditorium has a slanted curtain wall. The angle shields the sun rays from the interior of the auditorium in the summer months. The low sun rays in the winter is allowed to enter the building. The facade uses a unitized facade system supported by the truss and bolted to the slab.

The open sides apart from providing light gives a feeling of openness in an otherwise closed space underground. Assisted by the landscaping, it provides a sense of placeness.

The institution building contains several classrooms which are mostly used for training students in dance or classical music. The building consists of two identical structures which open towards each other. The close distance between the buildings keeps the corridor in shade for most of the day. The centre also acts as a courtyard which allows hot air to escape. Institution Section

Restaurant design This project was carried out during my ninth semester. It was an individual assignment project involing two subjects landscape design and project management. The objective was to design a commercial building in the core of the city. Factors such as return on investment and construction time were considered.

Restaurant Design With the site at the core city of Coimbatore, the brief was to design a restaurant in a very crowded street of Gandhipuram the major factors to consider for the project were noted.
The return on investment With the land prices taking a huge leap in the rapidly growing city, local rents of spaces took a leap. Being a commercial project, it is crucial to complete construction and start business at the quickest possible time in order to gain a return on investment.
Green space in the core of the city The rapid growth of the city had reduced the amount of green cover in the city. The intention of creating a green space in an already small piece of land was a great challenge.
The rising labour wages Rising labour charges are another challenge faced in Coimbatore. With workers getting daily wages it was important to complete the projects on time with the most efficient number of labours.
The duration of the project proved to be a factor concerning two of these problems. Using Cross Laminated Timber construction for this project was a solution to complete the construction quickly with a limited number of labour. Having provided CLT structures. Green walls were used on the facade and at the central courtyard of the building. The greenery induces freshness into the usually busy street.

Considering the span of the timber slabs, the plan was generated in a fixed grid with supports at regular intervals. The timber panels are cut to required shape at the factory and is transported to site. Five layered CLT panels were used. Though there are several methods of connection for assembling the timber panels, I chose to use connections that did not reveal or project Anchor and bolts connection

Multiuse Skyscraper Design Evolution Form Evolution Inspired from the city’s deep connections with kites, the concept was based on its aerodynamic body. Initially a tetrahedron shaped facade was planned.
Wind
By giving uneven surfaces through change in the floor space, a better result was achieved. The stepped floors helped reduce high wind speeds(yellow) to medium(red) or low(blue) speeds. Double glazed curtain walls are used in the facade.
Initially the facade was intended to deflect the wind. This allo we d the wind to acc umulate sp e e d and thus act with gre ate r f o rce at the e dge s. The facade was the n change d with mo re une ve nne ss in the sur f ace. Wind analysis for the initial design The wind analysis in Vasari showed wind speeds gaining speed as it travels along the surface of the building.

Multiuse Skyscraper Design Facade design The building uses a double facade. External facade comprises of a unitized curtain wall system. The system consists of rotatable photovoltaic panels at the spandrel. These panels are automated to rotate according to the position of the sun. They also act as shading elements. External facade is held by steel extrusions from the beam which are anchored to the floor beams. The internal curtain wall uses a stick system and extends from floor slab to the beam above it. since it is packed from top to bottom, it ensures a perimeter fire stop.
Hot air moves upwards and is forced out at the nearest refuge floor.

The core areas connect service lines between floors. This space is non occupiable and is for technical purposes only. It contains HVAC ducts, plumbing, electricity and drainage lines. The service lines for a set of floors is gathered and reorganized at the service/mechanical floors Outrigger systems are used to withstand the forces due to the wind.
The foundation consists of a rafted slab supported on a pile foundation.
Composite columns with both steel and reinforced concrete columns are used to provide strength.

Residence Living room design Type of Project: Residence design (7th semester Internship) Site Location: Bangalore, India Work done: Project Coordination, purchase handling and site supervision Project period: December 2013 - April 2014 Firm: Atto Atelier, Bangalore Principal Architect: Ar. George Attokaran Contact: +91 99000 54884 email: attoatelier@gmail.com
This live project was a great opportunity given to me by the firm. I coordinated the works in the project and simultaneously managed the purchases and the accounts involved in the project. During my internship, I spent most of my time on site and making purchases (lights, flooring material, modular kitchens, etc,.). The project involved the renovation of a residence in an apartment building in the heart of the city. The residence is located on the fourth floor of the apartment. The idea was to create a contemporary feel in the residence. Initially a lift was planned within the building. The idea was then substituted by a spiral staircase. The false ceiling design too had to be modified along with the change. The False ceililng and the spiral staircase were the two prime elements of the design. The complex shape forced us to create our own cast for the false ceiling. Every geometry of the pattern was documented and the shape was built manually at site.
page 19
Residence Living room design, False ceiling
The design of the false ceiling was complex as it had to be curved in such a way so that it merges with the other elements in the room and at the same time hide a beam that was passing through the centre of the hall. The complex shapes were fabricated as individual moulds in site using plaster of paris and assembled under supervision. Plastic fibres were used for reinforcement in the moulds.

Residence Living room Design, Spiral Staircase
The spiral staircase connecting the living room to a lounge upstairs replaced the lift planned during the design stages. The spiral staircase was constructed entirely of wood. The central pole and the steps are made from teak wood while the raiiling was built using strips cut from of plywood planks.

Residence Living Room Design, Pooja Room construction
The east facing pooja room was designed to obstruct a direct view to the kitchen from the living room. The curved structure was built using steel bars and chicken mesh. The angles of the bars were calculated and designed accordingly. The entire design idea was to create curved finishes in the living room. The concept of having curved surfaces throughout the room shaped the pooja room and the false ceiling. They had to merge with each other as well as the spiral staircase that was to be installed in the room.

Cinema Theatre interiors / renovation Type of Project: Professional (10 th semester) Site Location: Tirupur, TN, India Work done: Total redesign of the auditorium,the lobby and site supervision during execution. Project period: July 2014 - January 2015
Audience viewing angle was initially determined for various heights and the floor tiles were laid accordingly Screen
Manager: Mr.Boopathy Contact: +91 93623 29838
Having gained site handling experiences during my internship at ATTO Atelier, I took up this project when I was still in College. The project fund was limited and a deadline was fixed. The theatre which has been a landmark for over two decades needed a complete makeover from the facade, auditorium layout to the lobby interiors.

Cinema Theatre interiors / renovation After the removal of the existing seats, the entire floor was repaired and granite was laid for installing new seats. In order to reduce project cost most of the ceiling and wall coverings inside the auditorium were retained. They were repaired and painted to suit the auditorium’s new ambience. The canteen and lobby were also renovated and lighted.

Bollywood / Kollywood has a large number of ardent fans. With the maximum ticket prices limited in the state, the 760 seated theatre has to cater to audience of all classes. Special LED lights were fixed on walls which were usually lit during scenes of intense applaud from the audience (usually during an actor’s introduction scene).
