Daily listen

I have been consuming this podcast for breakfast, lunch and dinner. Jeffrey is obviously an expert but also passionately invested in making our earth more habitable for longer. Every person he brings on shares though values and has incredible lessons to teach.

Such inspiring content!

I’ve learned so much from this podcast. Such inspiring content and lovely people. And very accessible too :)

Full of all the good things!

Lovely people talking about lovely things. Full of insight and practical advice, a post cast still of fun and generosity. Jeffrey’s interviewing style is great to listen too and his holistic approach to building sustainability is one we could all take to heart.

Excellent Podcast,

This is a fantastic podcast and a treat to listen to. I have been working with wood/green wood since my teens, 52 now, and this is a breath of fresh air. ireally enjoyed the Dave Cockcroft and Barn the Spoon's episodes but have found myself listening to the others and as a result am looking in to the subject of green building with new eyes. Keep up the good work and thanks.

Well paced, friendly ramblechats with carefully selected sustainability experts!

As someone who works in digital design, I’m really thirsty for hands-on practical information about building sustainability in the real world. Jeffrey’s a lovely and respectful interviewer - so it feels less like a lecture, and more a chat around a campfire with mates. There are some really amazing perspectives on offer from carefully selected guests, and it really does shine a light on the level of innovation and dynamism of the sustainability movement in the UK. Highly recommend!

Perfect podcast

I wish I had found this sooner. Great line up of interviews, all on the subject of sustainable building or side topics such as craft. Listened to one episode so far but am downloading a selection. Great podcasting, not letting too much get in the way of the conversation, not too chummy or filled with in jokes, just really interesting content. Thanks so much and good luck!

Gentle, flowing, informative and easy to listen to.

I first found this podcast series when after I saw Flo Hamer’s tiny house build on a YouTube - wanted to find out more and then discovered she’d done an interview Jeffrey Hart. The interview felt so natural, like they were two best friends. Listening to further episodes has shown that Jeffrey manages to achieve that level of intimacy with all his guests. And, I’ve learned so much - as someone who has been interested (from an armchair) in cob building, I learned on one episode about cob in Scotland. There’s so much to interesting content, all at a great pace and in a great style. It’s my ‘go-to’ podcast right now. Love it!

Dream Podcast

If you had asked me what my ideal podcast line-up was, you couldn't have come up with a better range. I have thoroughly enjoyed all the podcasts so far and look forward to many more. A diverse range of characters, some well-known, and many not, with fascinating and in-depth conversations in an eco and ethical direction. Jeffrey has a very gentle, unassuming and inclusive interview style which is very welcome. I love this grassroots podcast with its egalitarian host.

One of my favourites!

Very interesting podcast with so much information about natural building and sustainability. An essential if you have any interesting in natural building, with a nice comedy touch from Joe and Jeffery!

Refreshing take on the construction industry
