The previous 4 pages are initial excercises I undertook to try and capture the essence and spatial qualities of a site I was working with previously. They are purely diagramatic rather than isometric.

They vary from time based to atmosphere to density of site and crowds. I believe these were the trigger point for my fascination with trajectories and the voids people and objects leave behind on a site.

Using particle flow simulation in 3DS Max I was able to simulate pull/gravitational and surface factors whilst simultaneously injecting particle flow into the site model.

Here a simple attractor definition is controlling repelling forces to map and represent a user trajectory through the site. This was a natural succession; instead of mapping voids, I used predetermined paths and data to create them digitally.
A two dimensional grid to create an attractor definition creates interesting, but sometimes predictable results. Apart from extruding directly upwards, there is minimal ability to create an envelope or even true spatial program. Using the paramters outlined from my initial studies of voids I must create a 3D space generation representation of my system.

After experimenting with particle flow and attractor fields, the next stage of this project was to try and create a genuine space. To detatch the project from the paper it derived on and into a responsive environment where it can quite literally grow. Using parametric modelling software, I developed and adapted a definition originally concieved by Daniel Piker. The definition algorithmically produces dendritic forms through a wandering point and a seed point. The seed point can be applied to any set geometry and the wandering point circumnavigates the seed and ‘connects’ when it comes within a set proximity and then loops over again. This can be executed in either 2D or 3D. Parameters can be set to control the action. The ‘pull’ is akin to a gravitational force, the stronger the pull, the denser and short the dendrites will be as the wandering point is pulled towards the seed point. ‘Proximity’ controls how far the wandering point has to be to attach itself to the seed and ‘wander’ controls the efficacy of the wandering point and level of Brownian motion. (Brownian Motion - the “seemingly random movement of particles in fluid”) Now I could be pro-active with the theory of ‘void’: create it myself, and then control a dendritic space frame that will react and respond to trajectories around it.
019
Attractor curves:
Simple Visual Basic script loops the attractor points around their respective curves. The curves are split via series and then evaluated to form even spacing around the linear form.
unit3B_nXtplatform
Mesh box vertices:
Using a plug-in for Grasshopper called WeaverBird I created the vertices on the outer surfaces whilst keeping the internal volume empty. This reduced lag and memory consumption.
Reactive Vertices:
To move the mesh I used a vector between two points (static and shifted) before flattening the tree and connecting it directly to the DLA script. This part of the definition is not too dissimilar from my earlier 2D attractor grid work.
Proximity:
I used a relatively simple proximity parameter here to control the dendrites as they produce. Once two vertex become within a certain distance they automatically connect, bypassing the DLA script.
Rectangle spaceframe definition added onto the end as an option. (later discarded.)
Attractor Path:
Attractor points move along these curves and as they come within close proximity of the mesh box, the mesh vertices are pulled towards it. Giving the box a fluctuating form as the points swing past.
Wandering Point:
The large circle indicates where the wandering point is born. the point works its way towards the mesh vertices until it meets a previous, now static, point and repeats.
Mesh Box:
Set to the site dimensions 3x12x12 metres and vertices are located along its outer surfaces.
Original seed point (red). It is now replaced by entire mesh box

Clear example of the vertices reacting to the attractor paths circling the mesh.
the wandering point does not follow a 2D path around the mesh like the attractor curves. As we can see here, the point approaches the mesh from 360째.

Diffusion-limited aggregation without any kind of proximity control within the definition:

Diffusion-limited aggregationwith proximity controls set in place. This created a self defined and limiting form:

unit3B_nXtplatform
Controlling the DLA definition was my greatest concern. As shown in previous pages, it worked well as a 2D dendritic form generating device. To turn this script into a workable, ‘space-frame’ definition I had to control its pull, proximity and the wandering point. The images on the left page are incredibly dense because I restricted the wandering seed and allowed the 3D generation to repeat over itself. Therefore creating a dense, chaotic form. The images on this page, shows the frame at later stages as it is branching further out and re-connecting itself. This was a result of increasing the proximity for the seed point as well as adding a small definition after the DLA which calculated if two point were within a set distance, if they were, the script would link these two points together. This creates a inter-linked frame that controls its own parameters rather than continually searching for a new boundary.
027
The diagram below shows us how the DLA definition would act if there was no proximity control in place. The seed point would create forms branching away from the ‘site’ (in my case, a mesh box) Obiously we cannot have an infinite area to work with. The following pages describe how I overcame this problem.

These images show a typical formation using the DLA definition. There is continuity visible and also ‘self-correction’ which adapts the form if a more economic linkage has been produced. These screen shots were captured every 100 rotations of the attractor paths, finally resulting in 1200 loops of the visual basics script. There becomes a point at which the form slows in its generation to a point of no real benefit. It is at this point that the final form is produced

These are the very first pavillion renderings I produce with the design process. There is a certain naivety to them but they capture the essence of what I was trying to create. The next stage was to develop the exacting process for an efficient design both technically and aesthetically.
unit3B_nXtplatform
An adaptation to the mesh is certainly required at this point. Now I know that the process works, a refined solution to the brief is the next step.

Here an area of density is apparent. This has resulted in the DLA linking points within close proximity in both perpendicular and diagonal directions.

Attempts to attach a material system of some description. It is at this point that we were notified we would be working with a material so I thought it suitable to jump ahead and begin experimenting now rather than later.

Implementation of second year work. Their brief was ‘east meets west’. Small 1:1 scale furniture was designed to fit with the pavillion proposal.
045
A rectangular frame was applied to the spaceframe curves. I quickly dropped this idea as I believe it rendered the pavillion ‘clunky’ and awkward to the eye. The grasshopper definition is provided on following pages.

Although at a later stage the notion of 1:1 scale architectural furniture inhabiting the pavillion was dropped. These pages show my attempt at accommodating the busy scheme with positioned apertures and a slightly over-sized mesh box.

Just before submitting my competition proposal I designed a subframe structure that would enable us to create and control the roof density and apertures. The subframe consists of a triangulated grid that attaches directly to the DLA space-frame.

Material Sponsorship Speedo_LZR_racer_
The product:
FINA banned the use of Speedo’s full body LZR racer swimsuits this year. This meant that Speedo had many thousands of un-used, un-saleable suits left over. They set a task for students across the country to design a way in which this material could be re-used. Both green, and clever marketing. The main problem we encountered was that the suits came as they were, a suit, rather than rolls of material. This meant we had to cut them down and think of a pattern to use as well as exploiting the materials physical properties. The material is incredibly thin and has panels which reduce stretch in certain directions. This aids the swimmer but makes adaptation into an architectural material difficult.

This is my final competition proposal. I decided against an angular frame and instead decided on a slightly curved subframe which attached to the primary frame. Apertures were cut to allow light through. These obviously could be changed or adapted if the design won.

These pages and the following two outline the requirements from the pavillion team for a landscape structure for our final design. The interior would house a moving hyperboloid scheme and the roof would be supported by 5 asymmetrical pilotis. The challenege was to design a scheme that not only fulfiled the brief, the requirements, but could also be built within budget and on time.

‘Pockets’ are outlined. This worked well with my earlier process of using trajectories to aid the design process. The pockets would either facilitate flow or provide intimate spaces.

Area we would like users to enter the pavillion.
Ideally we don’t want users entering the pavillion around this area.
Encourage entrance here too. Ideally raise this area to provide external seating. Waiting area for potential catwalk.
unit3B_nXtplatform
Implication of raised areas. lack of flow and raised areas decided to be ‘too defined.’
Attempt at an uneven flowing floor. This was a good idea but possibly lower sections rather than raise. One lowered section. Worked better aesthetically but stunted the idea of flow.
Final floor proposal. Lowered section encourages users to pass through the pavillion as we would like.

I used an inter-locking plywood lattice structure for the floor primary frame. All drawings are constructed predicting 18mm ply would be required and used. A limit of 2.5m was placed on each component. Ths was due to workshop manufacturing limitations. The frame was then split down into a 1.25m grid to provide load bearing stability for the sub structure decking.

Further Development: Implementing_processes_ learnt_on_the_nXt_Pavillion
The use of two mesh boxes as seed points allowed me to create a denser outer frame whilst leaving the interior space clear. The original one mesh concept had supporting structures in the centre of the form, hindering layout possibilities and adaptability.
unit3B_nXtplatform
107
Further development of the spaceframe resulted in my attempt to create a form free of a frame work. I wanted the final result to imply that my process was present, but not rely soley on this one methodology. Here we can see clad-work applied to the primary structure to form an enclosed space. The frame was removed leaving an angular, imposing form that I feel interacted well with the site. This process could easily be applied to differing sites and the results, naturally, would differ widely.
