# Holland–Bukit Timah Group Representation Constituency

The Holland–Bukit Timah Group Representation Constituency is a four-member Group Representation Constituency (GRC) located in the central, western and northern areas of Singapore. Holland–Bukit Timah GRC is known as amongst the wealthiest electoral divisions in the entire country, due to the predominance of Good Class Bungalows (GCB) landed homes, which are predominantly owned by the wealthiest citizens within the country. The GRC consists of four divisions: Cashew, Bukit Timah, Ulu Pandan and Zhenghua managed by Holland Bukit Panjang Town Council. The current MPs are Sim Ann, Vivian Balakrishnan, Christopher de Souza and Edward Chia from the People's Action Party (PAP).

## History

Originally known as the Holland–Bukit Panjang Group Representation Constituency, it was renamed to its present name 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. A large portion of Holland–Bukit Timah GRC is made up of jungle and nature reserve, namely the Bukit Timah Nature Reserve and the Central Water Catchment.
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 will then be moved from Jurong GRC to Holland-Bukit Timah GRC, whereas Junction 10 will be moved to Chua Chu Kang GRC.
