he application of long span timber structures within the cityscape presents an emerging typology; challenging the future environmental and socio-economic demands of the city. The prototypical Blackfriars Rail Bridge applies a multi-objective approach, considering both contextual configuration and the systemic development of a new timber construction system. Comprehensive research explored the historic applications of differential timber species within naval architecture and architecture; presenting an informative basis for future systems within the built environment. This research catalysed an iterative tectonic design process exploring the allocation and application of different timber species, utilising their individual properties in a composite system.
a unique load case at a specific point of the geometry. Liaison with industry leading advanced timber bridge engineers, Knippers Helbig, enabled the furthering of geometric precision and validity of the structural elements of the bridge. Construction methodologies and connections were further considered, ensuring feasibility of application within the urban realm.A digital tool was developed, automating the allocation of timber species within the long span block laminated system, considering key regulatory standards and allocating for structural, environmental and durability parameters, to achieve performative objectives. Presenting a sophisticated application of different species resonant to their performative qualities. This is experienced both in the structural composition of the bridge and in the tactility experienced by the user, enabling systemic
A prototypical design of the Blackfriars Rail Bridge and integrated North Terminal presented the opportunity for long spans and unique load conditions within the emerging typology of timber bridges. Challenging the conventional station typology, the rail bridge functions as both a major railway interchange for London and a public realm; connecting the north and south bank with a public ‘spine,’ with the north terminal presenting a seamless relationship between the terminal and waterfront. The project considers the bridge at the scales of both the differentiated lamella composition of individual components and the contextual configuration of a long span infrastructure proposal within the urban realm. The rail bridge geometry conveys an optimised, performative structure, derived through digital analysis and modelling tools, respondent to

It displays the potential for timber based performance boats and the longevity of timber as a construction material, winning the Giragila Regatta in 2016. Her narrow beam, deep keel and sweeping overhangs were the characteristics of a true racing yacht in her time.

ANISOTROPY OF WOOD Anisotropy gives wood unique properties in different directions. The advent of glulam removes natural deficiencies present in solid timber. Glulam is typically 50% stronger than its solid wood counterpart. The research focuses on glulam, formed from solid wood, retaining anisotropy, structural and durability properties whilst removing natural deficiencies.

Through considered connection design, the ability to vertically lift all elements into place will considerably reduce construction time and river disruption. Further block laminated sections are mechanically fixed into place.

he focus of this year’s work is the awareness that architecture can affect at deepest systemic leveland the understanding that architectural proposition is in itself a system of interrelated constituentswhere the findings of interdisciplinary systems theory apply. This knowledge opens a way to a method-driven approach that can materialize in architecture of great performance and considered expression while driving architectural authorship and novelty. We will aspire to reinstate the designer’s engagement with all aspects of the system’s constituents aiming for impactful architecture delivered by the negotiation of the interacting entities that define the unified spatial whole.
Societal, technological, cultural, economic as well as political developments will propel our investigations with a deep understanding of how they interlink. This will shape our strategies and heuristics, driving synthesis. The observation as well as re-examination of civilizatory developments will enable us to project near-future scenarios and position ourselves as avant-garde in the process of designing a comprehensive vision for the forthcoming. We will find out about how human endeavour, deep desire and visionary thought interrelate while they advance cultural as well as technological means, driving civilisation as highly developed organisation. Futurist speculation inspires and ultimately brings about significant change. Supported by competent research we will aim for systemic impact and amplify found nuclei into imaginative tales with architectural visions fuelled by speculation. Our methodology employs both bottom up and top down strategies in order to build up sophisticated architectural systems and will be tailored to the individual problem. Pivotal to this process and to fight charlatanism is the concept of practical experimentation – and intense exploration through both digital and physical models that aims to assess system performance and its direct application to architectural space. The emphasis on applied research fuels the process of design and allows us to develop highly considered architectural propositions with great momentum.
