Useful Studio creates arched weathering steel Chiswick Park Footbridge

London-based Useful Studio has connected a tube station to a business park in Chiswick, west London, with a pedestrian bridge made from weathering steel.

Named Chiswick Park Footbridge, the pedestrian bridge forms part of a route between a London Underground station and the Chiswick Business Park.

"The bridge is designed to enable better connectivity and a safe enjoyable journey between the business park and the wider community along with access to the transport network and Chiswick Tube Station," explained Catherine Ramsden founding director of Useful Studio.

The bridge was built from three weathering steel arches that increase in height from west to east as the spans grow. This means that the path curves around an existing building, creating the most efficient route.

Useful Studio chose the material due to its durable nature as the bridge's location over train lines means that any maintenance needed would be costly. The studio aimed to create a "zero maintenance" bridge.

"Bridges typically have a 120-year life which puts a huge performance demand on the materials and detailing," said Ramsden.

"Network Rail enhances this demand by restricting access for ongoing maintenance and retrofit. Work over live rail lines require a formal possession – these are exceptionally costly and require a long lead time for scheduling. Therefore it is better to design out this need by using materials that are self-weathering with a long life."

The weathering steel arches are connected by angled steel support ties to the bridge's deck to create a network arch structure.

The use of inclined support ties, which are linked together, creates a stiffer more stable structure meaning that less material was needed and mass dampers to control the vibrations of the footbridge were not needed.

"A network arch structure is the combination of the arch, the deck and critically, the tied inclined hangers. The network is achieved with the angled cables which are linked at their intersection," explained Ramsden.

"This system increases the stiffness and the stability of the structure," she continued.

"This solution emerged to provide stability to the very thin arch – in the pursuit of minimal material use – and to control the dynamic behaviour of the footbridge."

Although network arch structures have several benefits they are not often used for footbridges as they involve complex engineering Ramsden added.

"Network arch footbridges are sophisticated structures which require a very good understanding of the structural behaviour, detailed care in the architecture – in particular at the hangers intersection, and precision during construction – especially for the tuning of the hangers," she said.

"It requires very close collaboration between the design disciplines and the contractor to ensure success."

To construct the bridge Useful Studio created a "kit of parts" so that it could be largely fabricated off-site. Each of the arch sections was brought to site in five sections before being assembled and lifted into place.

This limited the amount of time spent working above the rail tracks.

Chiswick Park Footbridge has been longlisted in Dezeen Awards 2020 in the infrastructure category. Cullinan Studio and McGurk Architects energy building that captures excess heat from the London Underground to help warm over 1,000 buildings was also longlisted in the same category.

Suspended Orbs, Webs, and Air Plants Imagine an Alternative Ecological Future by Artist Tomás Saraceno

Three reflective spheres hover above the courtyard of Florence’s Palazzo Strozzi in Tomás Saraceno’s immersive installation.  The metallic orbs mirror the historic Renaissance architecture in addition to visitors who pass by, while marking the entrance to the imagined space that explores life beyond anthropocentrism. As its name suggests, Aria is concerned with air, encompassing human travel, its ability to foster growth, and how it’s entwined with every living organism.

The Argentinian artist (previously) is known for his large-scale works that fall at the intersection of science and art and consider the human toll on the natural world. Throughout Aria are various experiences dealing with contemporary environmental issues: Glass forms hang from the ceiling and house Tillandsia plants, which need only air to survive, while “A Thermodynamic Imaginary” considers the immensity of the sun and its unused potential.

Each of the works also references one of Saraceno’s 33 arachnomancy cards that explore ecological interconnectivity. References to arachnids manifest in the complex systems that hold Weaire–Phelan structures in “Connectome” or in the stark “Aerographies,” a series of clear balloons and framed networks that explore how “the movements of people, heat, animals, and spider/webs affect and are affected by the air,” a statement from Saraceno says.

Ecosystems have to be thought of as webs of interactions, within which each living being’s ecology co‐evolves, together with those of others. By focusing less on individuals and more on reciprocal relationships, we might think beyond what means are necessary to control our environments and more on the shared formation of our quotidian.

If you’re in Florence, stop by the Palazzo Strozzi to see Saraceno’s work before it closes on November 1, 2020. Otherwise, find out more about what he has planned for the rest of the year, which includes a new solar-powered balloon, on his site and Instagram. (via This Isn’t Happiness)

"I long for the day where suppressing my identity is no longer part of the job"

Black architects are forced to be palatable in order to be successful, says architectural designer Naila Opiangah, who shares her experiences of racism within the industry.

---

For months now, the discourse on race and equity has been predominant in every setting of our lives. Non-black people have had another series of introductions to the injustices faced by the black community.

This flux of attention on racism that emanated from police brutality is not a novel occurrence. In fact, in the short period of time I've lived in the US, from late 2012 to today, several murders of innocent black people by the police received similar attention and sparked protests by the Black Lives Matter movement.

Architecture has never been a haven for genuine racial discourse in my experience

What is different today is that the killings that occurred on 13 March, 25 May and 12 June triggered a reckoning on racial injustices at all levels of society, pushing the movement well into the architecture and design world.

Architecture has never been a haven for genuine racial discourse in my experience. In my opinion, it has been a petri dish for blatant racism. When I moved to the US from my home country of Gabon to study it and later to practice it, I did not expect that my success would be defined by how well I managed to suppress my black and African identity.

I learned early in the process that assimilation was a must in order for me to fit in a field where black people only account for a sliver of its members. This awareness came after direct and indirect forms of discrimination and microaggressions in school, from the studio workshops to the midterm and final reviews.

I also quickly realised that my mere presence, perceived as an oddity and often a threat, was something that I had to justify, not only with the quality of my work but also through the degree of my eloquence. One instance of the many microaggressions I was subjected to was when I was told by a guest juror that I was a better foreign student because of how articulate I was. However, I should quit talking about race so much as it distracted the audience from my otherwise good studio project.

Entering the professional practice of architecture was equivalent to graduating to a higher level of social gymnastics

I can also recall the time when one of my studio projects involved researching a neighbourhood in the Chicago South Side with all of my studio mates. Only one of them seemed truly committed to understanding that neighbourhood while the rest kept on sharing prejudiced and racist "observations" and fears of going on a studio visit in a predominantly black neighbourhood, that is "infested by gang violence".

Being the only black student in that group, I always tried to reassure them, but I ended up feeling defeated and exhausted.

Despite working extra hard to prove my worth as a student of the academic institutions I attended, it never felt good enough, and that shortfall followed me well beyond college. Entering the professional practice of architecture was equivalent to graduating to a higher level of social gymnastics.

I participated in the marginalisation of other black people by accepting the marginalisation I was subjected to

Considering that getting this far in the field is still so rare for a young black woman, I navigated these spheres resolute to constantly express my gratitude for such a chance. In a less sarcastic way, it meant that I defeatedly complied to the low assessment that was established of me, convincing myself that it was a sort of rite of passage. I participated in the marginalisation of other black people by accepting the marginalisation I was subjected to.

Early in my career, I accepted a position much lower than my qualifications because I believed my employers knew better. After months of doing my best to please them, I was told by one of the principals that he and the rest of the leadership team was very concerned by my communication style and tone. That comment came after I finally gathered the courage to ask for the better position I was "promised" to have. Blooming into my full self and attempting to exert my full potential was always something that I felt could negatively affect my career growth; unfortunately, it did.

Black people evolving in architecture and design face a disturbing amount of racism. It is insidious, vain and strategically set up to keep us away from the upper echelons of the practice.

Although a very few of us manage to make it as far as possible, the treatment of the majority of us remains increasingly appalling. As society tackles once again the issue of race and policing, I can't help but wish for architecture to address its own issues of policing of the black people who practice it. I long for the day where suppressing my identity is no longer part of the job. Until then, I weave my way through the spaces, enduring one gaslighting at a time.

Naila Opiangah is an architectural designer based in New York City. She moved to the US from Gabon seven years ago to study architecture and developed multiple interests throughout her time in college. From social advocacy, politics, art and business, Naila has explored ways through which architecture could engage other disciplines. She's worked in various reputable design offices and her experience led her to found the Architecture Is Complicit movement.

Layered Botanics Comprise Artist Vanessa Hogge’s Delicate Porcelain Assemblages

All images © Vanessa Hogge, courtesy of Ester Segarra/Vessel Gallery, shared with permission

Vanessa Hogge translates her lifelong fascination with flowers into monochromatic assemblages of hydrangeas, roses, and myriad blossoms. The London-based artist (previously) has been working on EFFLORESCENCE, which is comprised of three ceramics, since October 2019. Each of the delicate porcelain pieces is adorned with innumerable hand-sculpted florets and leaves that blossom from a central base.

Rather than studying horticulture textbooks and the intricacies of plant life, Hogge works entirely from her memory and imagination and frequents gardens and other places where organic elements thrive for observation. “I’ve traveled to research in the Okavango Swamps in Botswana, the flower-filled valleys of the Northern Cape in South Africa, and this January (just before lockdown), to Southern India to be surrounded by the exotic vegetation there—just beautiful,” she tells Colossal.

Hogge’s inspirations, though, are vast. She imbues elements of the funky textiles created in the 1970s, miniature depictions of Indian gardens, and Frida Kahlo’s iconic flowers. “As an artist, the variety of their forms and structures is immense and endless. People comment and wonder when I will move on and if I will tire of flowers, but how can I? This fascination is also steeped in my family matriarchs—strong women gardeners and the great outdoors,” she says.

The artist offers a brief look into her studio and process in this short video and on Instagram. You also might enjoy Hitomi Hosono’s intricate vessels.

Japanese house is "a gymnast's delight" says commenter

In this week's comments update, readers are critiquing a Japanese home designed by Suzuko Yamada and sharing their views on other top stories.

A house in Tokyo has caused a stir thanks to a scaffold of steel pipes and platforms, which connect the house to its garden and can be adapted according to the owner's needs.

Yamada designed the three-storey house and its gabled roof to be entirely clad in sheets of corrugated metal, apart from the front facing side.

"The architectural equivalent of a rich hipster dressing like they're poor"

Some readers are not impressed. "The architectural equivalent of a rich hipster dressing like they're poor," said Wilson MK.

Paul Bateman agreed: "What a visual blight on the neighbourhood. Forever a building site."

"Love the playfulness of this house and could imagine the occupants having a lot of fun with the building over the years," said Reg on the other hand. "I can appreciate that this piece of reconfigurable architecture would certainly not be to everyone's taste, however I can't help but admire it."

"The perfect set of monkey bars," concluded Aigoual. "A gymnast's delight."

"Quitting flying was probably the trickiest thing" says carbon neutral architect

"People were doing things like this in the 1980s" says reader

Readers are discussing Buro Happold's director of sustainability Maria Smith's declaration that she has made herself carbon neutral. Smith has gone vegan and stopped flying.

"A lot of people were doing things like this in the 1980s," said Bras Cubas. "Hitchhiking, eating muesli, no kids, building passive houses, second-hand clothes, using furniture found in the street. Here we are 40 years later and nothing new to tell."

"Choosing not to have kids to reduce your carbon footprint?" continued Heywood Floyd. "That's the beginning of the end right there."

E§7Jack was more positive: "What do these comments prove? That working from home makes people really grumpy, perhaps. For a lot of people this article is inspirational and will help people change their own behaviours for the better."

Four times Melania Trump made headlines for architecture and design

Commenter says Melania Trump has "done what most architecture students want to do" 

Despite abandoning her architecture studies to become a model and then marry Donald Trump, Melania Trump is demonstrably still interested in design. We rounded-up four times the first lady hit the headlines, most recently with her redesign of the White House's Rose Garden, sparking reader debate.

"She only made headlines because she is the first lady," said Chris. "The projects associated with her are banal at best and not worth discussion."

Flying Saucer disagreed: "If this was Michelle Obama's work it would be on the cover of the NYT Style Mag complete with fawning accolades. The hatred for this woman is palpable."

"I have no hate for Melania," added Erich Trumpelstiltskin. "She's done what most architecture students and practicing architects want – to quit architecture and marry into wealth instead."

Sea Stone is a concrete-like material made from shells

"Please get these materials into commercial construction" says reader

Waste seashells salvaged from the seafood and aquaculture industries have been ground down and bound to create a sustainable material that resembles concrete, dividing readers.

"Please get these materials into commercial construction ASAP," said Rustbeltbrett. "Even if only as a cladding material."

"Had that idea years ago," added Troy Smith Studio. "Glad to see someone is doing it. Think of the endless shells of oysters alone. The banks of Manhattan are built on them in places."

"Why do we need this?" asked Takki, who was less keen. "Surely this waste product decomposes without any issues to the environment."
