Singapore - from the worst to the best housing system in the world:

Singapore has one of the world’s most sustainable housing planning systems, with more than 80% of the population lives in public housing and 90% of which own their own house, according to the Housing and Development Board. This is possible thanks to the government's housing provision strategy and financial support since the 1960s, including the Home Ownership Scheme, Allocation and pricing, Financial planning, and Home Protection Scheme. Today, Singapore is becoming a smarter city by using technology in housing planning to achieve sustainable living for its citizens. Some of the highlighted technologies include My Waterway @ Punggol (Singapore's first man-made waterway that won numerous awards for transforming the town into a "waterfront town of the 21st century") the Living laboratory (where the new sustainable initiatives in urban planning, design, and green building solutions are test-bedded). HDB also sets the goal to achieve net-zero-energy for common services through the solar capacity building program, in which the design of the solar photovoltaic systems has been optimized to maximize solar power generation for each HDB residential block.
