Aaron Betsky is a US-based writer, educator and critic, who has served as director of the Cincinnati Art Museum and the Netherlands Architecture Institute, as well as a curator of architecture and design at the San Francisco Museum of Modern Art. 

He has also written over 20 books with subjects ranging from Zaha Hadid, Frank Lloyd Wright, and the Dutch architecture practice MVRDV to the relationship between architecture and same-sex desire. 

He is about to publish another. Don’t Build, Rebuild: The Case for Imaginative Reuse in Architecture implores the construction industry to refrain from doing what it does most – building – and, instead, find new ways to use the materials and stock we already possess. 

In this episode, we talk about: the trauma of election day in the US; how we can reuse buildings imaginatively and effectively; working with relics of the industrial age; why the digital world is changing the architect’s role; making spaces more egalitarian; squatting; what architects can learn from artists; urban mining; taking inspiration from music festivals; hanging out in the legendary Studio 54; the importance of loft living; and much, much more.

(This episode was recorded on election day in the US.)

Nicole Rycroft is the founder and executive director of the award-winning environmental not-for-profit, Canopy. Since it launched in 1999, the Vancouver-based organisation has worked with more than 950 companies – including Marks & Spencer, Tesco and Puma – to ‘develop innovative solutions and make their supply chains more sustainable to help protect our world’s remaining ancient and endangered forests’. 

It started by looking at the book industry and persuading publishers to use more recycled paper, before turning its attention to packaging and fashion – shining a light on the industry’s use of viscose, in particular. 

Nicole has won a slew of awards and was recently named in the Business of Fashion’s top 500 most influential people. 

In this episode we talk about: being a ‘professional treehugger’; dealing with textile waste in India; how viscose is made and its negative effect on the environment; developing new manufacturing models for the material; working with major fashion brands to help them become more circular; her journey from physiotherapist and rower in Australia to activist in Canada; how contracting a life-threatening virus changed her life; running her first environmental organisation at nine years old; documenting human rights violations in Burma; and successfully greening the Harry Potter books with JK Rowling.

Todd Bracher is a US-based product designer who has worked with brands such as Humanscale, 3M, Herman Miller, Georg Jensen and Issey Miyake through his eponymous studio, winning a slew of awards along the way. 

More recently, he created another company, Betterlab, in which he collaborates with scientists and innovators to, in his words, ‘shape emerging research and foundational technologies into game-changing products’. The company has taken a particular interest in the potential of light, for medical and other, perhaps unexpected, uses. 

Todd’s latest project is a book. Design in Context, which is out now, illustrates how design – and design-led thinking – has the potential to change and shape every facet of business.

In this episode we talk about: generating value for different clients; the importance of collaboration; why he launched Betterlab; how he’s using light to combat myopia; finding truth in design; how light becomes a material; learning to shape rather than style it; working with UVC and creating extraordinary products for health environments; leaving the US to study in Copenhagen; working in Milan; learning the ‘business of design’ under Tom Dixon; and designing net positive furniture for Humanscale.

Zena Holloway is a bio-designer and founder of Rootfull, which creates exquisite clothes, lights and sculptures from grass roots. 

She started her career as an underwater photographer, doing extraordinary high-end fashion shoots, as well as working with the likes of Kylie Minogue, Tom Daley, Katie Price and numerous other celebrities. At the same time, she was capturing the effects of pollution on the UK’s river beds. 

So how and why did her career shift so dramatically?

In this episode Grant and Zena talk about: how she came to work with wheatgrass; early lessons with other materials; why her process is like a school experiment; how beeswax provided a Eureka! moment; ‘collaborating’ with her material; roots’ potential in industry; working with Kylie; giving up underwater photography and becoming a full-time bio-designer; creating new products with fashion designer Phoebe English; being fuelled by optimism; oh and stealing her son’s Lego.

Alkesh Parmar is a designer and researcher. Over the years, he has hollowed out champagne corks and turned them into chandeliers, as well as transforming traditional Indian terracotta cups into light fittings. But he is best known for his work with citrus peel in general – and orange peel in particular.

Using a material generally thought of as waste, he has created a variety of extraordinary products including a juicer (for obvious reasons) and a lampshade. His practice combines craft with critical design and, it’s fair to say, he was a relatively early adopter in the design industry of working with local materials and questioning the effects of globalisation.

When he’s not working with waste, he is also a teacher at the Royal College of Art. 

Alkesh was one of the stars of the Material Matters fair when it launched in 2022 and he’s returning to Bargehouse when the doors open for the 2024 edition, which runs from 18-21 September. 

In this episode we talk about: why he’s researching the history of oranges for the Material Matters fair; the properties of orange peel and how it can behave like leather; how he sources his material of choice; the importance of failure to his practice; not wanting to run a large company; coming from a family of shoemakers; and his relationship with light.

Sanne Visser is a Dutch-born, London-based designer. She describes herself as a ‘material explorer, maker and researcher’, who is best known for a string of installations and products using human hair. Since graduating from Central Saint Martins a little under a decade ago, she has exhibited all over the world and been nominated for a number of awards. 

Happily too, she will be one of the stars of this year’s Material Matters fair – taking place at Bargehouse, Oxo Tower Wharf from 18-21 September – with an installation called, Locally Grown, that invites visitors to explore their hair as a new material. Essentially, people will able to have a free hair cut and then (if they stick around long enough) watch it being spun and turned into rope. Sounds kind of interesting right? 

In this episode she talks about: her installation at the Material Matters fair (obviously); how she became fascinated by hair in the first instance; the processes she puts the material through; its (quite) extraordinary properties; the ethics around ownership of designing with hair; creating new material systems; collaborating with makers, hairdressers and scientists; the products it’s possible to make with hair; coming from a creative family; finding school testing; and the importance of teaching to her practice.

Artist Bharti Kher was brought up in England before moving to India almost on a whim in the early ’90s. Since then, she has established herself as a major player on the international art scene. 

Her sculptures talk about women’s place in society and the female body. She has a fascination with mythology and mixing the real with the magical, as well as a profound interest in materials and found objects. She has melted down bangles, used saris, and ceramic figures, as well as casting people with plaster. But she’s best known for her work using bindis, made from felt. 

And she will be using bindis to create a huge piece on London’s Southbank, which opens in September. Right now, she has a wonderful exhibition at Yorkshire Sculpture Park, entitled Bharti Kher: Alchemies, which shows a range of pieces from 2000-2024.

In this episode she talks about: using things she finds – from radiators to bangles; how objects have inherent narratives and why she ‘exhausts’ them; the importance of bindis; breaking things; her fascination with negative space; casting people in plaster; growing up in Epsom and loving art from a young age; travelling to New Delhi on the toss of a coin; and being married to a fellow artist.

Ernest Scheyder is an author and senior correspondent for Reuters. His new book, The War Below: Lithium, Copper, and the Global Battle to Power Our Lives, looks at the impact of the green transition in the US – and, more particularly, the tensions over the increasing need to mine for metals to decarbonise the grid (and power a plethora of devices) against the nation’s desire to conserve the environment. 

The book illustrates how materials effect geo-politics and the urge for energy security, inform the national debate, and impact at a very local level. It also suggests that  becoming more sustainable is anything but straightforward.

In this episode we talk about: why lithium and copper are vital to our futures; where the materials are mined and processed; 'material colonialism'; how the pandemic changed perceptions of our supply chains; why some mineral-rich nations are excluding the US; the role of China in the 21st century global economy and the withering of US hegemony; the new ‘green arms race’; why mining is in a ‘perpetual state of decline’; the tension between local desires and global needs; the role of religion and conservation; child labour in the Democratic Republic of Congo;  the ‘dualistic’ policies of President Biden; and Scheyder’s issue with leaf blowers…
