Over $100 billion in active construction across Greater London. The Elizabeth line already changed how the city moves. HS2 is reshaping the entire country. Battersea Power Station – derelict for 40 years – is now one of the most ambitious regeneration projects on the planet. And Heathrow's third runway debate has been running for over 20 years.
