Every housing system on earth has one. No regulator publishes it. Everyone who has lived below it knows exactly where it is. Above the line, a home keeps out the weather, keeps the family safe, gives a child a place to study, and stays put from one year to the next. Below it, none of that can be relied upon — and everything else in life gets harder as a result. What sits on the line is not complicated: → Shelter that holds, for decades not seasons → Safety, and a door that lo

Yes. It already has been, on four continents. The question is why we are still arguing about it. Industrialisation is not a factory. That one misunderstanding has burned more money than any technical failure. A factory is one part of a chain running from land and brief through funding, design, manufacture, assembly, handover and maintenance. Bolt a factory onto an unchanged process and you have an expensive shed with one customer. Why it is so slow → A bank will lend against

Stop asking “wind or solar?” Start asking “what does this place have?” Decentralisation Pt2. Energy. The decentralisation conversation has collapsed into two options — panels on the roof, turbine on the hill. It’s a poverty of imagination, and it’s costing communities the energy that’s already under their feet. Every location has an energy signature. Read it properly and the options multiply: → A fast stream or a weir on an old mill site? Micro-hydro runs day and night, seaso

There is an alternative that is greener than zero. We’ve spent a decade treating “net zero” as the summit. But zero is just the point where we stop making things worse. It is not the same as making things better — and it quietly accepts a model where energy is generated far away, pushed down long wires, and metered to people who had no say in any of it. There is another route. Instead of pouring national money into ever-larger grid-scale generation and the transmission upgrad
