Week Three

Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental type of fabrication techniques in the reading. Outline the three techniques and discuss the potential of Computer Numeric Controlled fabrication with parametric modelling. (150 words max)

The three fabrication techniques Kolerevic describes are subtractive fabrication, additive fabrication and formative fabrication. Subtractive fabrication involves removing a specific volume of material from solids using multi-axis milling processes; additive fabrication involves adding material incrementally in a layer-by-layer system; formative fabrication involves reshaping or deforming material into the desired shape by adding mechanical forces, restricted forces, heat or steam to it. Computer Numeric Controlled (CNC) fabrication has the potential to enable mass customization and multiple variations with parametric modelling. It bypasses the processes of parametric modelling by moving to direct file-to-design production and enables the production of multiple iterations and variations. The architect will therefore no longer be restricted by the constructability of designs being produced, as they can be experimented with digitally.

Week Three

Surface Creation

Surface iteration 1

Surface iteration 2

Surface iteration 3

Final surface iteration

Using the grasshopper script, I created different surface iterations in order to create surfaces that appear to interact with one another. Out of the four iterations, I chose the structure that subtly curves around one another - one appearing to reach out and the other pulling back. I felt this iteration best represents my design concept of organic growth as the surfaces fit with the panels I created well, and surface iterations that were too curved posed a challenge for me to experiment with various paneling.

Week Four Panels & Waffle

Inspired by the concept of plant climbers, I created panels that reflect the organic movement of plants climbing a trellis.

The waffle structure was developed using two surfaces: one appears to be reaching towards the other while the other pulls back.

For the first surface (left), I used perforated 3D panels to develop a lattice-like structure which creates transparency that enables ventilation and light to enter the internal space, and also panels that are partially perforated to provide a sense of shade and privacy.

My design intention was to have the waffle curve and taper towards the top, emulating a seedling sprouting from the ground. The opening at the top of the structure creates an internal volume which - when inside - guides the visitor’s viewpoint towards the sky. The internal contours of the waffle also create the effect of movement like the growth of a seedling towards the sunlight.

The paneling for the second surface (right) also emulated this concept in a simpler version, using panels that are partially perforated and 3D. These panels were rotated in various directions to create a geometric pattern that radiates from the middle. By adding a point attractor at the top of the panel surface, the panels grow in size as they move towards the top of the structure, demonstrating the idea of growth.

Week Four

Laser Cutting

During the process of creating a Laser Cut file, I found it particularly diifficult to unroll panels for more curved surfaces and had to manually create tabs or join them in some instances. I have learnt to utilise simpler panels for more complex surfaces to not only complement the structure but to also create better developable surfaces.

Boolean form 2

Boolean form 3

Final Boolean form

Using Lunchbox on Grasshopper and Rhino3D, I experimented with different geometries and liked the effects the torus (‘donut’) shape which created columns and the spaces around them in its boolean form. At the same I wanted to create a more geometric pattern in my boolean form and decided to use the platonic icosahedron with a circle cutout though the centre. This created an interesting columnade system which guides circulation routes and form open corridors and intimate spaces at different levels where the geometries intersect with the cube.

Week Five

Isometric

I chose a platonic icosahedron as my geometry and created a circular opening through the centre of the shape. When the geometry was booleaned and contained within the boundaries of the cube form, this created a system of columnades as supporting structures and organic geode patterns that form an interesting ceiling design. The intersecting geometries with the surface create spaces for circulation, while the column forms act as points of attraction that guide movement and determine thresholds as people are either drawn towards or navigate around them in the space. Different levels are created which form variations in height and also a sense of division in thresholds. Areas where the geometries intersect the cube surface also create openings that add porosity for ventilation and light to enter the space.

Task 01 Matrix To illustrate my design concept of organic growth, I experimented with surfaces that appear to be moving towards or curving around one another. I chose my final iteration as the surfaces demonstrate subtle movement whilst allows for more complex panelling as opposed to the other surfaces that curve more dramatically but require simpler paneling.

Task 02 Matrix I experimeted with different geometries using different attractors i.e. point, curve and random attractors before deciding on my final iteration which utilises both curve and point attractors. I feel the curve attractor helps to illustrate the growing movement demonstrated in my Task 1 model whilst the point attractors create variation in size and geometric layout. I chose the geometry platonic icosahedron as I liked the geometric patterns it created and its overall shape is almost spherical, which I felt would produce interesting geode patterns.
