• Planner's footnote to your roofs: the block that stops most of them is not the owner, it is the parking ratio. Add a flat, add a space — and the yard has none. Three cities have dropped that rule for existing buildings and conversions doubled within two years.

• Answering:“What do you wish someone had asked before a decision that affected…”

  Who was not in the room, and why. Before any vote I would like that written down as plainly as the result: who was invited, who came, and who could not have come even if they had wanted to.

• In ten years the council agenda arrives in plain language a week early, a drawn panel of residents sits beside the elected ones on the big questions, and losing a vote no longer feels like being erased. None of it is exotic. All of it exists somewhere already.

• Answering:“What have you seen working somewhere that more people should know about?”

  Vienna's rule that publicly funded housing keeps its rent limits permanently, not for twenty years. German cities rebuy the same flats every generation because somebody wrote an end date into the contract.

• They get a working group. A working group is where an idea goes to be documented instead of tried. The ones that survive are usually the ones somebody just did, badly, first.

• A neutral chair for our neighbourhood planning group. We have argued about the same junction for two years, and the loudest three of us — I am one — have made it impossible for anyone else to speak.

• Answering:“What do people trust you to help with?”

  Reading a plan or a budget and saying what it actually does. Municipal documents are written to be technically public and practically unreadable. I already do this for neighbours; I would happily do it for anyone here.

• That we both distrust our own first explanation. I would rather share a method with a stranger than a conclusion — conclusions we can argue about afterwards.

• A real utopia has to survive its own maintenance. Anyone can design the opening day. Show me who sweeps the square in year eleven, who pays for the lift when it breaks, and who is allowed to change the rules — then I will believe it.

• Supporting this from the planning side: signal priority plus dedicated lanes at the eight junctions you name would cut end-to-end tram times measurably — this is the cheapest capacity gain available to this city, and the parking spaces it costs are countable on two hands.

• Land value capture is the policy nobody campaigns on: when the city builds a tram line, nearby land values jump, and the increase — created entirely by public money — lands in private pockets. Taxing that windfall could fund the next line. Vienna does versions of this. We donate it.

• An exercise I give every planning student: stand in a public square for one hour and count the places to sit that cost nothing. In most German city centres the answer fits on one hand. The bench is the cheapest social infrastructure ever invented, and we removed it on purpose.

• Segregation in this city is produced, not chosen: housing allocation, school catchments, transit gaps — each defensible alone, together they sort people by origin and income with quiet efficiency. If you want mixed neighbourhoods, you have to plan them. The default setting of the market is sorting.

• Planning consultations reach homeowners over 50 with reliable precision and almost no one else. Not because others do not care — because the formats presume time, language and confidence. We moved one consultation into the football club and doubled attendance. The venue is the invitation.

• Every heat action plan I have reviewed treats trees as decoration. A mature street tree cools like several air conditioners and costs a fraction over its life. The obstacle is underground: pipes, cables, parking. Whoever coordinates the subsurface coordinates the climate of the street.

• Traffic evaporation is real and nobody believes it: close a road and a measurable share of car trips simply do not reappear elsewhere — people reschedule, combine, or skip them. We have thirty years of data. Yet every street redesign here starts from the assumption that today's traffic is a constant of nature.

• As a planner I keep seeing the same trap: we debate new construction for years while the cheapest housing policy — protecting existing tenants from displacement — gets treated as radical. A city that loses its cleaners, carers and cooks to the periphery has not solved housing, whatever it built.
