Temporary Pavilion Structures (1)

The Temporary Pavilion by Matthias Loebermann

Temporary pavilion used as a meeting place for athletes and media space and press to come to after their competition. At the ski competition, it was obviously the winter and structures often covered with snow.

As the pavilion was built only a tie rod, rope and pallets, demolition and recycling structures simple enough after the competition finished. Loeberman pallets used to encourage people to look at common items in a new light as a building material back in 2005, is still a relatively new concept for most people.

It was made entirely from 1300 shipping pallets and held together with tie rods and pull straps. The pavillion was used as a meeting place and media room for the athletes competing in the championship.

Apparently they dismantled and recycled the structure after the event, however I think this would be a pretty amazing permanent structure if it could survive in a particular climate without any major damage.

Back in 2005, Matthias Loebermann while building a beautiful pavilion out of shipping pallets reclamation for the Nordic Ski Alpine World Championship in Oberstdorf, Germany.

Shipping pallets are found all over the world and makes for a sturdy building materials at low cost, which explains the remarkable resurrection Palletecture projects lately.

Temporary Pavilion [C] Space in London

Designed in collaboration with Alan Demsey , [C]Space is the winning entry in the AADRL10 Pavilion Competition. It is an advanced technology concrete structure that was erected in Bedford Square London in March 2008 to commemorate the 10 year anniversary of the Design Research Laboratory Graduate Design Program at the Architectural Association.

The pavilion is formed by a discontinuous shell structure spanning over 10m made of thin fibre reinforced concrete elements which perform as structure and skin, floor walls and furniture. The concrete is manufactured by the Austrian company Rieder, and the design of the pavilion takes the material to new technical limits, which required extensive prototyping and material testing during the design development process.

The jointing of discrete concrete profiles exploits the tensile strength of Fibre-C and a simple intersecting notch joint which is locked together using a bespoke rubber gasket assembly. The angle of intersection at each joint continuously varies across the structure.

The entire design process was conducted using 3D digital and physical modelling, and the design development was completed using rigorous constraint modelling and scripting to control over 850 individually different profiles and 2000 joints. Finally, the elements were manufactured directly from digital models on CNC cutting equipment.

The winning design was chosen anonymously from 28 entries by invited jurors and was selected based on the following points: constructability within a tight schedule and budget, simplicity and elegant form, effective use of material, and a pavilion as a continuous extension of furniture to roof structure.

The striking presence of the pavilion invites inspection from a distance and upon closer interaction reveals its ambiguity through the merging of sinuous curves, structural performance, and programmatic functions into a single continuous form. Fibre-C elements perform as structure and skin, floor, walls and furniture.

As you move around, the surface varies from opaque to transparent, producing a stunning three-dimensional moiré. The surface encloses while also providing a route through for passing pedestrians. It has neither inside nor outside.

The jointing system in the pavilion exploits the high tensile strength of Fibre-C using a simple interlocking cross joint which is tightened by slightly bending each element as it is locked into consecutive cross elements.

Consultation with the Fibre-C technical department in Austria has suggested that a flex of 15-20mm per metre can be applied without affecting the structural performance of the material. The appearance of small micro cracks on the surface is mitigated by using lighter material colours and a Ferro finish. The pavilion is fabricated from curved profiles that are nested on standard 13mm flat sheets and water cut. Once delivered to site the entire pavillion can be constructed by hand.
