The government is planning to build 700,000 new homes by 2030 to meet the projected increase in population to up to 6.9 million in about 20 years. Market observers said that the key challenge is to ensure that the supply of housing and supporting infrastructure rolled out is in line with population growth. The government plans to roll out some 200,000 new homes by 2016 and it is setting aside land to build another 500,000 units till 2030. Plans are also in the pipeline to improve transport infrastructure. Eight hundred buses will be added over the next five years. And by 2030, Singapore’s rail network will double to 360 kilometres from 178 kilometres currently.
