tions. This would give us an overview of the language of our fabricated models would give off. This stage gave us quite an insight about materials with respect to light, structural integrity, economic efficiency, user experience, architectural language conveyed. Moving on from the first hand experience of experimenting with material, we have learned rhino, as a form generating tool, with no limits to our imagination. Rhino has been quite an imagination stimulator as it is so different from the rest of the programs used. It’s flexibility has been the key factor. It is the key program when thinking massing and architectural language as it focuses completely on form. I am shahenda , as an architecture student, this course has been the ultimately complimenting tool to design. Starting off with experimentation of material, we have learned different aspects of material through trial and error. Next, I have always been so ambitious in design forms and ideas; however, digital implementation has always been a struggle. our digital abilities are merely limited to the programs we have been using like autocad, revit and photoshop. In this course, we have mastered skills that would help us to stimulate our imagination and design ambitions. Experimenting with material has been a helpful tool to model design. It was such a realistic process as to how this specific material would react with real-life condi-
Moving on from the form generation,Next stage has been the parametric integration that gives the f. Since rhino has been a form generating tool, grasshopper has been the logical implementation of the form. Both programs are complimentary and are adequate to create an unlimited yet sequential logic design.
First hand experimentation with a variety of materials to understand the cause and effect of variable factors.
01 Understanding Material
2 EXPERIMENTING WITH FOAM: Material Brief: Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes drilled in into a cavity of a finished wall. “Spray foam� is also an informal term used to refer to various plastic foam materials that are used in building construction to provide thermal insulation and minimize air infiltration. Polyurethane and polyisocyanurate are two types of foam used in this application. Sprayed compressable foam. Texture: experimented with humidity effect. Property: settles and take the shape of the mold. experimentation process: - Humidity Conditioning. - Application of pressure

5 Foam reaction with respect to Light.
Polyurethane Foam provides a complete, seamless building envelope, creating a more comfortable indoor environment for the life of your home. So, it has a relatively insulative character; however, it manipulates light penetration instead of completely blocking it. Spray polyurethane foam (SPF) insulation can be categorized into two different types: light-density open-cell spray foam insulation and medium-density closed-cell spray foam insulation. Both types of SPF are thermoset cellular plastics comprising millions of small cells. Because of its variable density composition which depends on the humidity and compressibility of the foam , the light penetration intensity varies with the process variables of the foam drying up.

Combining Foam with a complimenting material, Gypsum.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4¡2H2O.[3] It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard. The gypsum exhibits material properties that compliment the foam. Gypsum is more structurally stable than foam. However, foam penetrares light, while gypsum completely blocks light. so this combination can also be used for light manipulation. The gypsum is such a brittle material; however, the foam is a ductile one. Tenacity:Flexible, inelastic Luster:Vitreous to silky, pearly, or waxy Streak:White Diaphaneity:Transparent to translucent

02 Capturing Mobility
12 The site is located at the outskirts of the campus, where it is visible and accessible to different user groups.
The site is a place where the university assembles vegetation for nuturing and distrubuting them among campus.
The site is of a 360 view, making it visible from everywhere and value each facade equally.
Limitation: the accessibility points to the site are rather hidden.

13 The site consists many vegetations of many types, giving the natural character unity but with diversity.
The surrounding elevation is of a higher platform, making it more visible and providing shade.
The site is experienced by several user groups: people of auc and outsiders.
The site is surrounded by many water features, providing a natural expression as well cooling.

Enhancing visual connectivity and experiential symbiosis: as if the site is living within the pavillion. This is created through creating an abstract exhibition that corresponds to the site’s exisiting surroundings, through the manipulation of the openings as well as the form. Creating the analogy of a tree and making it the primary source inspiration as it the most dominant feature on site, taking the idea of branching out with transitional states from one solid center the starting point of the form genertation.

1- The model implements the transition of states concept, but structurally unstable.
2- The model has been blocking the light; neglecting site connectivity.
3 & 8: the model has not been stable as it rises from ground, neglects also site connectivity.
4- The site creates the tree analogy to literal and sturcturally impossible openings.

5- The structure is based on subtractive elements; however, it isn’t structurally stable & not coherent with concept.
6- This has been the closest to the form as it structurally stable and functional and echos the concept greatly.
7-This has been an initial idea where openings failed to stabilize as it needs structure on a perpendicular axes.
9- The model isn’t continuous and isnt structurally stable without a perpendicular axes of structure.

The final product after many ittirations of trial and error.
The model impelements the visual connectivity that corresponds to site’s surroundings. The model has been structurally stable enough to endure the live loads. The model exhibits a central node that the structure branches out from. Also, intensity is reflected upon the model, tranisitional states are reflected upon the form’s fluctuating ductility.
