Void deck

A void deck is an open space found on the ground floor of HDB blocks in Singapore. It is used for community activities.
History.
At first, HDB blocks did not have void decks in the 1960s. The Housing and Development Board changed the design of the blocks and made the first level free of flats for activities such as light industrial workshops. However, the term "void deck" was not mentioned in HDB's annual reports until 1977–1978. Precinct pavilions are added to newer void decks.
Decoration.
Artists need to ask relevant authorities for permission before displaying their works as the space is not theirs.
Newer void decks.
Some void decks are now not located on the ground floor and are integrated with sky gardens. Newer void decks are also smaller in size.
