Traditionally, architectural units made of brick or concrete are small and multiple, heavy, difficult to vary, and are much better in compression than tension. Using carbon fiber filaments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, pound for pound, have higher capacities in both compression and tension and therefore impact the design in both the vertical and horizontal dimensions. Most importantly, however, our units address the use of carbon fiber at the scale of architectural production.

The computer script we wrote to generate the final form for the piece had to be able to produce widely varying sectional shapes, but also had to conform precisely to children’s body dimensions. Once written, we then could input conditional statements to control the table, bench, lounge, and variable “bump” heights.
Our early variations explored the use of double curved surfaces and alternative leg supports.
The final design responds to particular site conditions and utilizes the curvature and “landing” of the surface for self-support in addition to steel legs which follow the same geometry of the surface.
Since we were also going to be the fabricators on the project we made a series of scale models to study and refine the geometry in greater detail, and also to understand the process of fabrication and assembly of the final full scale piece.
For ease of fabrication, transport, and assembly, the final design is divided into seven sections. The steel support legs also serve a secondary role of joining the sections to each other.
Each section is broken down into smaller elements which overlap to create a stronger bonding surface. Dowel holes are drilled in each part to facilitate alignment and rapid assembly.
We developed cut sheets for CNC and Water-Jet cutting of both the wood and steel elements. It’s important to note that these were output directly from a 3D model to cutting files – no construction documents were made for the project.
After CNC machining, elements are laid out in order prior to assembly. Sections are glued and clamped in stages.
Parts are cleaned and sanded prior to section assembly.

This project is part of ongoing research that investigates the utilization of a 7-axis robot for hotwire cutting casting molds from EPS foam stock for the purposes of casting variable concrete units. The projects conceptual basis is the rethinking of the masonry block as a variable unit. Rhinoceros with Python computer scripting is explored as a methodology for producing the variable units – which are aggregated to form continuous structural surface forms. Surfaces from the design models are imported to Master Cam to produce tool-pathing and G-code to run a robot controlled hotwire. Multiple molds are cut from 4’ x 8’ sheets of fully recyclable EPS foam – with average cutting time of each part being under 3 minutes. Through exploring the full span of the design and production process from coding to casting to assembly the project aims are to investigate both the efficiency of the system and its formal/structure/ornamental potentials. The aesthetic desire being to produce a form and unit design which is intricate – more like lace – possessing the texture and tactility of concrete – but having a lightness of form and linament which is perceptually other.
Our Runner-Up entry to the 2010 TEX-FAB Repeat design competition.
tetra | n project is based on the desire to design a generative
self-supporting structure capable of variable form – through utilizing a
single robust detail – one which could be fabricated out of flat stock
material. tetra | n project accomplishes this through two means. First is
the development of part geometry based on a tetrahedron (see diagram) –
structured in this way – the generation of more complex geometry through
simple base geometry always produces well – formed planar objects.
Additionally, coincident faces of adjacent tetrahedrons always produce
continuous forms – joints always meet correctly – regardless of the
position or scale of the next part. Secondly – through the utilization of
Rhinoscript – highly complex variable formed structures of n tetrahedrons
are possible. The script is ‘run’ on an assembled tetrahedral base
structure – part generation, connective element generation, labeling,
drill holes, and part flattening are integral functions of the script.
tetra | n is formed as a single unified tower structure with an occupiable
base that supports itself simply by standing on the ground. Depth and
redundancy in the form develop not only a robust structure – but a level
of complexity and intricacy found only in organic forms. The visual effect
is of a structure that is, on the one hand, highly ordered, rigorous and
geometric, and on the other degenerates into near chaos, simulates organic
growth, and confounds clear distinctions between foreground and background.
