FABberz cofounder + Pablo Rica Runner Up for [AA FAB RESEARCH CLUSTER]

IMAGE FABberz cofounder Josiah Barnes and his partner, Pablo Rica are runners up for the AA FAB RESEARCH CLUSTER competition with their project, MUSCULAR SYNERGY.




The FAB Research Cluster at the Architectural Association in London announces the results of the 2009 AA|FAB Awards. The Award theme was ‘Designing Fabrication’ and the jury was interested in recently built projects that exemplify the innovative integration of design and fabrication processes through digitally driven design systems and protocols, and whose completion contributes to an international discourse on the use of emerging design and fabrication technologies.

Entries were received from all over the world including the UK, Spain, Austria, US, Canada, Japan, China, Hong Kong, and Australia. Due to the uneven distribution of entries across the categories suggested in the brief, the jury decided to reorganise all submissions into either INTERIOR or EXTERIOR groups.  Accordingly, it was agreed to reallocate the prize money into six awards, with a first prize of £1500 and two runners-up of £750 for each group.

The jury met on Thursday 11 June and was impressed by the extremely high standard and diversity of the submitted work. After four hours of deliberation they unanimously selected the following schemes for awards:



RUNNER UP: THE MORNING LINE Matthew Ritchie with Aranda/Lasch and Daniel Bosia

RUNNER UP: MUSCULAR SYNERGY Josiah Barnes and Pablo Rica


FIRST PRIZE: CEILING CLOUD Andrew Vrana, Joe Meppelink and Scott Marble

RUNNER UP: GREEN VOID Chris Bosse, Tobias Wallisser, Alexander Rieck, LAVA


The six award recipients will present their work at an AA|FAB conference during London Design Festival week from 19-27 September. A further eighteen entries have been selected for exhibition in September.

Parahelix by Joshia Barnes and Raquel Gallego Lorenzo After the structure was modelled, the horizontal and vertical sections had to be nested in order to lasercut them on two sheets of 2.9 cm thick wood. After calibrating the machine properly,the pieces were successfully cut in approximately 1.5 hours.

The assembly process began with the placement of the regularly placed horizontal sections at 3AM on center.  Once the structure of the horizontal sections was stabilized by several intersecting vertical sections,the assembly process was able to be completed by adding vertical elements one by one.

After the pipe structure was completed, white glue was utilized to secure the joint connections.Once dry, Parahelix was structurally sound.

Degrees of Freedom

The telescopic joint structure that we developed allows for an overall increase in size of 200%.  This number can be augmented by adding overlapping members, creating an antenna-like mechanism.  After the development of two Grasshopper definitions which entail the length change of mass amounts of curves, the idea of creating a physical testing model arose.  We chose to concentrate on the physical development of the phylotaxis definition.  The ¨digital¨phylotaxis allows for a free range of movement in twenty different positions.  When we translated this into the physical realm, the most important aim was to demonstrate the ability of the structure to both change in size and collapse in on itself.  The model, which was constructed with acrylic rods and silicon tubing, can be seen in both the videos and images below.  The use of silicon joints between each telescope allowed us to maintain a large degree of flexibility, while at the same time securing the structure as a whole.degrees of freedom
