THE PROJECT The traditional Teahouse as a space for holding conversation within

The notion of continuing the teahouse conversation beyond the physical walls

MODEL PROCESS Configuring the bamboo sticks to create a flexible structure. Even though flexible, this structure was rigid when bent to certain positions. Its flexibility allowed for a multitude of variations for structure and design

Using a closed structure form stemming from the lattice variations of column-like structures were formed. Varying the heights and bottom diamter allowed for the proposal of different functions below each space - also doubling as structural supports for the roof structure

WIND LOAD ANALYSIS Using Mesh surfaces extracted from 3D models, winds loads for monsoons of 80m/s were applied to the SW end of the build to evaluate the structural stability of the proposal.

KARAMBA STRUCTURAL ANALYSIS Structural Members Displacement (cm)

ROOF DEFLECTION Point loads applied to the affected roof surface showed major deflection at the SW end of the roof thus there was a need to provide additional structures to stabilize the area.

ADDITIONAL LATTICE BRACE Lattice Brace was added to stabalize the roof deflection.

AXONOMETRIC The overlapping of function and structure as influenced by overall landscape. The Openness of the structure allows for a free flow of movement and thought, stimulating the notion of flexible arrangment. This structure remains primarily a teahouse however can shape itself to the needs the the students/ teachers/public within may need in order to begin the process of continual learning.

CIRCULATION THROUGH

MAIN KITCHEN-TEA FUNCTION OPEN SPACE - VISUAL CONNECTION

SECTION A-A Larger spaces open up to form lecture like theatres for the architectural school use and also doubles as a larger group teahouse fucntion. The lower portion of the site tucks away for the more private individual to enjoy a quite study space or a peaceful tea break, or to share a moment with a friend.

SECTION B-B The teahouse operates from the centre of the design, as the heart of the structure it is the core foundation of the beginning of conversation. Without the function of the teahouse and the operation that it holds within, these conversations will ceise to exist.

SECTION C-C The sight line through allows for street visibility for future development that may be apparent on beyond and also respects the visual aesthetic of the existing landscape. The user is able to weave their way through the space moving between different platforms of visualy hierarchies that lend itself to various conversation that coud take place.
