LONDON - On Monday 29 January, the London Committee of the CTBUH United Kingdom Chapter held the event “Geometry of Tall Buildings” at the Auditorium of RIBA Headquarters in London. The event was chaired by Viviana Muscettola, CTBUH UK Chapter Advisory Board Member and Associate Director at Zaha Hadid Architects, and Katrin Foerster, ABB’s International Key Account Executive for Architects. The aim was to have an open conversation between leading architects and structural engineers around the geometry of tall buildings and its impact in the design trends for the future.

The evening was the result of the collaboration between, ZHA, ABB and CTBUH’s UK Chapter in London and gathered over 350 people from the local professional community.



 
The impressive panel included: Patrik Schumacher (Zaha Hadid Architects), Anil Hira, CTBUH India Vice-Chair (BuroHappold Engineering), Kai-Uwe Bergman (Bjarke Ingels Group), Chris Carroll (Arup), Bernhardt Doerstel (ABB), Dominic Bettison (WilkinsonEyre), Kamran Moazami (WSP) and Eric Parry (Eric Parry Architects).

The evening became an extensive back-and-forth between architects and engineers, all advocating for their agendas in design innovation.

Patrik Schumacher, Principal, Zaha Hadid Architects (ZHA), broke the ice by postulating a “parametrical tectonism,” an exploration that moves from vernacular structures to contemporary systems, which has opened new ways to conceive geometry in architecture. This is one of the seeds of ZHA’s formal and spatial innovation in tall buildings during the past years, which have challenged rationalism in favor of innovative para-geometries. The mix of research proposals and built realities displayed by Schumacher demonstrated that ZHA’s creative engine is still at full throttle.

Anil Hira, Regional Director of India for BuroHappold Engineering, took a more pragmatic approach, reminding the audience that despite design intentions, the structure is the main driver when designing tall. Also, that symmetry, the choice of materials and shapes that make sense are key to final success. Hira insisted on the importance of bringing engineers to the design from the very first stages of the design.


Kamran Moazami, Head of Discipline, Building Structures, WSP, discussed crucial factors for success in the design process.

Kai-Uwe Bergmann, Partner, Bjarke Ingels Group (BIG), displayed a different approach to the geometry of tall buildings, the one coming from a sort of “creative pragmatism,” where restrictions and urban regulations are transformed into advantages rather than obstacles. He took the audience into a fascinating trip through BIG’s “courtscraper” project VIA 57 WEST in Manhattan, the still in-progress Spiral tower, also in New York, and the recently opened “landscraper” in London that serves as Google’s UK headquarters. Other stops included Seattle, Calgary and Shenzhen. All of the buildings shown emerged from rejecting the “Modernist box” catalogue in favor of smarter, more energy-efficient and seductive massing options connected to the surrounding urban habitat.

Bernhard Doerstel, Global Product Group Manager, Building Automation, ABB, highlighted how the Corbusian statement “the house is a machine for living” has been overtaken by a more holistic approach to smart technology and the Internet of Things. His vision of the backbone of tall buildings is not only structural, but also technological, and he shared his view on how the tech backbone allows buildings to be connected to the cloud and exchange information. This exchange is making them “smarter” and able to resolve the problems of energy savings, traffic and high-density environments. His discourse was supported by built examples from Australia, the US and Canada, and the United Arab Emirates.

Arup’s mastermind behind some of the most iconic high-rise structures in the world, Chris Carroll, issued the evening’s second call for pragmatism, giving some striking comparative examples of the loads and stresses supported by tall buildings. While showing some of Arup’s latest works in Guangzhou, San Francisco, and Taiwan, he illustrated the development of mega-elements (grids, braces and columns), and advocated for “smartness” while making optimization-oriented decisions that have huge technical and financial impact.

 
Dominic Bettison, Director, WilkinsonEyre made a more lyrical discourse, seeking to identify the main drivers in designing tall towers’ geometry. Starting with his firm’s tower proposals and realizations below 300 meters, then moving to the more challenging realm of supertall (300-meter-plus) towers, Bettison underlined the struggle to find geometrical beauty and elegance while solving the inherent structural problems. He also highlighted how rapidly towers are getting taller, and how -- when going supertall -- there is not just one “ideal solution,” but many paths inspired by nature, optimization and aerodynamics.

 
The esteemed Geometry of Tall Buildings panelists
Kamran Moazami, Head of Discipline, Building Structures, WSP pushed for a holistic approach to the design process, and the commitment to economic viability, as crucial factors of success. He also emphasized geography, land value, height, and materials as parameters to be added to the geometry design mix. Moazami walked through his impressive tower portfolio, including joint work with many of the other presenters, showing how each case is different, because the mix of people and context involved is also different.


The last presentation came from Eric Parry, Principal, Eric Parry Architects, who first referred to the atmospheric paintings of C.F. David, and then showed an exquisite collection of hand-drawn sketches of European and American urban landscapes, using these to advocate for values such as axiality and monumentality. These are also sources for geometric inspiration when architects have the responsibility to transform the skyline of a city. It was a voluntarily “low-tech” prelude to his latest tower 1 Undershaft, the soon-to-be tallest building in the City of London’s Square Mile. Parry also reflected on the subject of permanence, as designs like the one coming from his drawing board will transform the future skyline of London forever.


The panelists spoke to a large, enthusiastic group.

The evening closed with words of gratitude from CTBUH Chairman Steve Watts, Partner, alinea Consulting, and questions from the audience focusing on the challenges of permanence and adaptability in tall buildings.

It was beautiful to see all the presenters at the end, geometrically aligned in a horizontal row, knowing they had conquered the realm of the vertical.
