Queen Victoria Garden Pavilion

Cascade Pavilion

Rhino Grasshopper

I’m interested in the experiential qualities of design and how a space can ultimately manipulate or enhance our moods. I believe that architecture can be an art, and there is more to it than just a building that shelters.

Within this subject I’ve learnt about the importance of thresholds, circulation and conceptual designing.

I now understand that we do not need a definitive concept idea to begin a design, and that we can realise our idea during the process.

My aspiration as a designer is to create an experience that can leave an impact even after leaving the created space. In my pavilion, The Cascade, I’ve created a singular circulation route that weaves in and out of the pavilion in which gradually becomes narrow and wider at each respective entry point. I wanted to engage with users whereby I created a mist/drip effect at the apex of the pavilion.

I aim to improve on my digital design skills, specifically in grasshopper, and fabrication techniques. This can be reflected in my PWavilion where I believe I could incorporate more scripting techniques to engage better with the existing environment.

The 2011 Serpentine Pavilion by Peter Zumthor restricts the freedom to interpret the functions and usage of the internal opening space. It is characterised by narrow coridors, dark and monotonous colours and an ominous play with lighting.

The absence of asymmetry makes this pavilion rather relaxing to move through as you are generally directed by the clear circulation routes throughout. The pavilion, in fact, isolates the users from the outside world by enclosing them in a double layer of wall structure.

This isometric represents the pavilion’s finishes, structure and internal relationships. I decided to also show the lighting which hangs in the narrow corridors to highlight Zumthor’s intention to lead users through the corridors using lighting. I’ve learnt that the circulation is rather simple but effecting, and the threshold accentuates these effects. Moreover, the construction is equally as simple, with arrays of the same wooden structure throughout the entire building, meeting at the corners seamlessly.

The thresholds can be found on the outer layer of the building as well as the internal walls. The circulation thus informs the design, being very symmetric.

THRESHOLDS

CIRCULATION

I utilised lighting as a threshold because it could also manipulate the way Circulation 1:200 the building feels, whether internal or external. I also used the wooden structural elements to inform the shape of the structure, as well as the cladding which accentuates the cohesivity of the design.

The cirulation is simple but strong, The internal doors were explicilty Thresholds (Permeability) 1:200 displaced from the centres of the outdoor thresholds, forcing users to walk through the narrow corridors which opens up into a large garden.

This creates a dramatic change of experience in users 4

The variable parameters are the grid sizes, grid offsets, referenced geometries and surfaces.

I wanted to create a seamless flow between the panels and the surface to create fatter and flatter grid sizes in the middle of surface two to mimic the smoothness of water within the waves, and use smaller grid sizes for the edges to imitate dripping water. A similar approach was used for surface 1 as well.

3 different referenced geometries were used

The design intention of the panels was to emulate the vicious nature of water colliding and the lightness of the air bubbles formed.

To achieve this, a base geometry of 2 quadrangle pyramid shapes with triangle cut outs on each side facing the top were referenced. The panel were then manipulated by grid size and grid offsets using attractor points.

Laser Cutting Geometries

surface and waffle physical model 9

The laser cutting file was taken from the FABLAB website. To create the panels and waffle structure, the grasshopper mesh was turned into NURBS and then unrolled. However, the waffle structure was made directly from the grasshopper script before baking it into rhino. Each panel was laid out using the layers used in the fablab template (red for etch and black for cut). The etched lines were for folding. I had to cut the triangles out by hand as the faces it created while unrolling were unruly.

Solid

and

SOLID

VOID

Speculating the form as voids creates a space that evokes curiosity as the forms that had been removed is not necessarily clear. The voids that cut through the cube create openings that allow light in, as well as create a relationship between the inside and outside

Speculating the void as a solid creates a sense of monumentality due to how congealed and concrete it stands. Circulation through this form would prove difficult without more intervention

Artefact as an Interface

Artefact as an Enclosure

This iteration explores the solid as a podium or column, or as an object.

This iteraction speculates the artefact as meeting point between inside and outside, such as a wall.

This artefact investigate the potential of an enclosure with a skylight.

The variables are grid manipulation, object variations and object manipulation.

I wanted to create an open bottom to by having larger geometries placed there, and a formal top to create a aesthetic lighting conditions.

Fabrication Process The support filaments were picked out using a stanly knife and some edges were sanded to create the smooth artefacts.

M3 - Cascade Pavilion

Exploded Isometric

Rain water can be captured through the ridges that lead into the internal threshold. A mist machine can thus filter this and create a more pleasant water experience for users The ridges can be climbed and used as seating or a place for play

Leelee Chea - 913999

LED strip lighting is placed in the internal ridges to create a Tron-like experience throughout the pavilion

External wall separates the pavilion off from the the rest of the garden, creating a sense of curiosisty that compells visitors to walk around to enter.

The seating provided along the perimeter of the pavilion follows the slope of the ground, leading into the pavilion

The entrance leads to a narrow opening that suddenly expands. This singular circulation route creates a controlled sense of vertigo within the sloping grounds, emphasising the pavilion’s sense of intimacy.

Topmix Permeable Concrete is used as a drainage solution for this pavilion

Wall along the perimeter of the pavilion divides the circulation route, providing visitors with circulation paths that create two vastly different experiences

The contrasting materiality of concrete walls and metal cladding of the pavilion accentuates the change in level.

Design Iteration

The Ripples of the Waves

The Sounds of the Shells

The Shell on the Beach

This iteration was to emulate the waves and shells of a beach, similar to M2 waffle and surface design idea.

However it was much too large.

The design intention was to create hollow tubes through the design to amplify noise and create musical sounds from the wind. Although cool in concept, it was too dificult to realise in model making.

This design iteration explored internal movement and circulation. This shape was hence used as the base shape for the final design.

Fabrication Process

The model was boolean split from the original 1:1 model and scaled to 1:25.

The base was unrolled and laid to be laser cut by the FABLAB.

A prototype of the pavilion was printed by splitting it for a cheaper and faster turn around time.

The final pavilion was roated into place in maker bot for the optimal printing process and to maintain structural integrity.

26

The walls were split for cost effectiveness since it didnt need to be structurally sound.
