In this episode, we sit down with Becky Little, an artist, builder, and earth enthusiast, who shares her journey from traditional building to her deeply rooted, place-based art. Becky discusses her Orkney project, EarthBound Orkney, which draws on the land’s Neolithic history, combining locally sourced earth materials to create tactile art pieces that celebrate and reflect the landscape.

Becky explains the influence of geology and place on her work, touching on the ancient methods and materials she integrates, including soil samples, clay mortars, and stone. She explores the philosophy of call and response, as she adapts to the materials and surroundings in a practice that is as much about process as it is about the final product. Additionally, we delve into her fascination with seaweed, which she's woven into her art, embodying the transient nature of materials and place.

Beyond the technicalities of working with earth and natural materials, Becky speaks passionately about the narrative power of her art to connect viewers with the history and future of sustainable, local building practices. This episode captures the essence of art born from nature, sustainability, and an artist’s journey to discover deeper, timeless connections to the earth.

Tony and Faith wanted to live a simple low-impact life, so built a little roundhouse on some land in Wales. Little did they know that the lengthy resulting battle to stay in their home would be part of the beginning of the flagship One Planet Policy. We talk about building the roundhouse, filled with tips and learnings before discussing the legal battles with an incredibly inspiring tale.

Many thanks to Tony and Faith - Have a listen and let me know what you think!

The second part of my conversation with Janna. In this episode we get into the nitty gritty of airtightness, and how we've come to appreciate its need, while not being 100% happy about the materials needed to achieve it. We talk about the importance of fresh air in your building, how C02 will make us unhealthy and sluggish, plus the best way to get the fresh air without losing all your heat.

In this episode of the Building Sustainability podcast, I am excited to welcome back architect Janna Laan Lomas, who shares her journey of building a sustainable home in Herefordshire alongside her partner, Seb, and her parents. We discuss the unique multi-generational aspect of their project, the thoughtful design considerations that have shaped their vision, and the innovative construction methods they are using, such as screw pile foundations and timber frames filled with cellulose insulation. Janna emphasises the importance of minimising embodied carbon, reusing materials, and creating a home that is both functional and environmentally friendly. Join us for an inspiring conversation about the practicalities of sustainable architecture and the emotional journey of turning a lifelong dream into reality!

A bonus episode with Archeologist Caroline Nicolay.

The conversation explores building sustainable structures with chalk and earth materials, sharing experiences with chalk as a construction material and unique techniques like milk and cheese curd floors. The dialogue dives into experimentation with lime washes, thatching roofs with bracken, and the traditional practice of thatching within communities.

They also touch on the circular evolution of housing practices and the symbolism of spoons in historical contexts. Topics include community involvement in thatching projects, the reuse of materials in buildings, and the layers of history created in landscapes through generations.
