#43: Primal City (Part 2) - Housing for Homo Sapiens

It turns out what's good for us is also good for the planet. How can we design housing for human beings that aligns with our evolution? In this episode I talk about how Co-Housing and Eco-Village concepts could be a proxy for hunter gatherer tribes by creating small, cooperative communities within urban settings. This way of living has huge benefits for our wellbeing and can also be an effective way of minimising energy and resource use. A Win-Win for people and the environment. Resources...


#42: Primal City (Part 1): Why Urbanists Should Study Hunter Gatherers

This episode is part 1 of a series about human evolution, our prehistory and Hunter Gatherer ways of life. Why should urbanists be interested in this? In this episode I make the argument that: This means that our pre-history should be a key design consideration in architecture and urban design. In part 2 (and maybe 3) I will set out specifically what this means for urban design. Sources: Civilised to Death, Christopher Ryan Sapiens, Yuval Noah Harari Uncivilised Genes, Gustav...

#37: The Problem with Net Zero Carbon (an Urban Design Perspective)
