Singapore lacks land and this causes interesting land use problems. In the city state they ran into issues around housing their citizens ranging from land to cost. Instead of letting “market forces” dictate their housing plan (like in Toronto) the politicians of Singapore decided to act. They built housing and funded even more to ensure that in Singapore everyone will be able to afford a home.
Singapore had a severe housing shortage decades ago. But it developed one of the world’s best public housing programs, which has also allowed a huge number of its citizens to buy their own homes.
