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.BS129 LinksRebearth - https://www.rebearth.co.uk/EBUKI Earthbound Orkney- https://www.ebuki.co/projects-1/earthbound-orkneyEarthbound Orkney BOOK - https://www.orcadian.co.uk/shop/orkney-history/1520-earthbound-orkney.htmlOrcadian basin https://en.wikipedia.org/wiki/Orcadian_BasinSkara Brae - https://www.historicenvironment.scot/visit-a-place/places/skara-brae/overview/Ness of brodgar - https://www.nessofbrodgar.co.uk/Maeshowe - https://www.orkneyology.com/maeshowe.htmlDaniel Podcast - https://www.buildingsustainabilitypodcast.com/historical-turf-construction-daniel-postma-/Art and Archaeology masters degree - https://archaeologyorkney.com/2023/07/24/art-archaeology-2023/Rowland Keable - https://rammedearthconsulting.com/Sand Talk - Tyson-Yunkaporta BOOK - https://assets.ikhnaie.link/click.html?wgcampaignid=1615880&wgprogramid=10671&wgtarget=https://www.hive.co.uk/Product/Tyson-Yunkaporta/Sand-Talk--How-Indigenous-Thinking-Can-Save-the-World/29943931books donated by - https://www.instagram.com/steve_brown_ceramics?igsh=bWphNzQxeGFhb280 Support the show and get bonus content on Patreon Hosted on Acast.

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.

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.Grain Architecture - https://www.grainarchitecture.co.uk/Architype - https://www.architype.co.uk/Llamacroft - https://www.llama-croft.com/Seb Twitter - https://twitter.com/SebLaanLomasCO2 Monitor - https://uk.rs-online.com/web/p/air-quality-monitors/2676379No more digging - https://nomoredigging.co.uk/Stop Digging - https://stopdigging.co.uk/Firth Construction - https://www.firthconstruction.co.uk/Centre for Alternative Technology CAT - https://cat.org.uk/IndiNature - https://www.indinature.co/Insulation Saw! - https://www.toolstation.com/bahco-insulation-handsaw/p97588John Gilbert Architecture - http://www.johngilbert.co.uk/21 Degrees (windows) - https://www.weare21degrees.co.uk/Connect with me:IG - @jeffreythenaturalbuilderFacebook - JeffreythenaturalbuilderSupport this podcast - https://www.patreon.com/buildingsustainability Support the show and get bonus content on Patreon Hosted on Acast.
