What this is
A practitioner conversation about viability. Each episode examines the physical, financial and political constraints that determine what gets built, grounded in operating experience rather than commentary.
Why I host this
I host Substrate as a practitioner, not a commentator.
I have spent 18 years working across real estate: as a surveyor, institutional fund manager, private equity operator and entrepreneur. I have built and scaled platforms in strategic land, housebuilding and affordable housing, and I have worked with global institutions, banks, founders and both public and private vehicles.
Along the way I have built deeply integrated technology solutions to improve data, systems and operational efficiency inside real asset businesses, which means I think about physical constraints and digital infrastructure from the same desk.
I am currently a co-founder of Alterx, Cora and Zen Living, and advise Barwood Land.
The conversations on Substrate reflect that proximity to delivery, and to failure.
What this is not
No advocacy. No easy optimism. No technology evangelism. The focus is on bottlenecks, trade-offs, second-order effects and delivery risk.
Before Substrate
From 2018 to 2021 I hosted a built-environment podcast: 38 episodes with guests including Mark Farmer, Nicholas Boys Smith, Fiona Fletcher-Smith, Indy Johar and Dror Poleg. Substrate is narrower and harder-edged: fewer episodes, one thesis, and guests who control the constraint rather than comment on it.
Who listens
Investors and developers who recognise that grid capacity now shapes land value, and that capital duration determines what gets built. If you work in real assets, these forces affect your balance sheet.
The constraint logic does not stop at real estate. Where this goes after Season 1.
