History

Originally known as the Holland–Bukit Panjang Group Representation Constituency, it was renamed to its present name in 2006 due to the Bukit Panjang ward of the GRC being carved out to form a Single Member Constituency, in return the Bukit Timah Single Member Constituency was absorbed.

Before 2011, Buona Vista division was in this GRC, which was transferred to Tanjong Pagar GRC, and Moulmein division was transferred to Moulmein–Kallang Group Representation Constituency, based on demographic changes. Lim Swee Say was moved to East Coast GRC to replace S. Jayakumar at that time. In 2025, Bukit Timah Hill estate was moved from Jurong East–Bukit Batok GRC to Holland–Bukit Timah GRC, whereas Junction 10 was moved to Chua Chu Kang GRC.

Since its establishment in 2006, the PAP has won every contest in this division. The Singapore Democratic Party (SDP) has contested in this division since 2011, but has never won over 40% of the vote in subsequent elections.^[1]

Constituency profile

A large portion of Holland–Bukit Timah GRC is made up of greenery and nature reserves, namely the Bukit Timah Nature Reserve, the Rifle Range Nature Park, the Central Water Catchment and the preserved Bukit Timah railway station as part of the Rail Corridor. The Singapore Zoo, Night Safari and Bird Paradise are also located in this division.

Holland–Bukit Timah GRC is also known as amongst the wealthiest electoral divisions in the entire country, due to the predominance of multimillion-dollar private housing, which are predominantly owned by the wealthiest residents of the country. However, parts of the GRC also include the more middle income Bukit Panjang estate that are not a part of Bukit Panjang SMC.^[1]
