Shelter and Viewing Platform in the Quitralco Fjord, Patagonia, CHILE
The project is a shelter and viewing platform located in an immaculate location on a mountain slope of Hacienda Quiltraco, which offers fantastic views of the Quitralco Fjord. The project consists of a generic platform on a raft foundation made from timber logs and planks and a shelter that consists of two ruled surfaces made from straight equal width timber planks. Ruled surfaces were chosen in response to the pre-manufacturing constraints of timber on site, the available construction means and the local knowledge in timber construction. A ruled surface is a surface that can be swept out by moving a line in space. This implies that such a surface can be constructed from straight elements, such as, in this case straight timber planks.
The aim was to demonstrate how from the application of a relatively simple building element and method a complex and beautiful form could arise that corresponds with the slopes of the mountains that frame the fjord. The two surfaces that make up the shelter are symmetrical and lean against one another. The combination of the weight of the surfaces and their flexible connection enabled resistance of the completed structure to the impact of the strong earthquakes of the region. At the end of the construction phase an earthquake at the scale of 5 on the Richter-scale occurred without consequences for the structure. The rotation points of the ruled surfaces shift along a curve in space resulting in a surface that seems to turn upon itself. This creates a raised opening where the two surfaces meet and the timber planks cantilever. Due to the north-south orientation of the shelter and the orientation of the opening to the south the Southern Cross can been seen through the opening at a specific time of the night.

AA Component Membrane
The AA Component Membrane is a permanent canopy for the roof terrace of the Architectural Association in London. Following a commission by the AA director the canopy was designed and manufactured by EmTech in collaboration with Buro Happold in just 7 weeks.
As the existing substructure of the terrace can not withstand high torsional forces resulting from wind pressure we decided to design a porous structure with a high degree of permeability for wind, light and views. The related material system is based on a simple membran component consisting of a steel framework and a membrane which acts as a loadberaing stressed skin element.
The related component design evolution is mainly based on the negotiation of three critical criteria. The structural behaviour was developed with the engineers form Buro Happold in such a way that the pretensioned membrane elements become an integral, load bearing part of the system, not just a cladding on a spaceframe structure. Another important factor is the shading behaviour of the canopy in different seasons and at different times of day, and the anticipation of percepitation and the related drainage of rainwater across the porous surface articulation, which was also digitally simulated and tested. Thus the parametric model becomes the interface for a design evolution leading to a higher level of performative integration while at the same time it also derives all relevant data for the manufacturing and assembly of the steel structure consisting of 600 geometrically different parts and 150 different membrane elements. The resulting overlapping membrane articulation protects the terrace from rain while at the same time remaining porous enough to avoid excessive wind pressure or blocking the view across London’s roofscape. Furthermore the membranes contribute considerable to the stiffness of the overall structure.
