HDB Flats are public housing units in Singapore, built and managed by the Housing and Development Board. They provide affordable living options for the majority of the population, with various designs and sizes to accommodate different family needs. These flats are typically located in well-planned neighborhoods, offering access to amenities like schools, parks, and public transport. The government encourages home ownership, and many residents buy their flats through various schemes, making HDB Flats a significant part of Singapore's urban landscape and social fabric.
