Project Background



The HSK/HT NDA occupies an area of approximately 714 hectares and is located at the north-western part of the New Territories, midway between the Tuen Mun and Tin Shui Wai New Towns.  The sites included scatted land pieces in the area near-by the proposed HSK Station, bounded by Castle Peak Road (Hung Shui Kiu) Castle Peak Road to the south, Kong Sham Western Highway to the west and Tin Shui Wai MTR Station.  The HSK/HT NDA will provide associated engineering infrastructure and supply land for subsequent development of public and private housing, community facilities, commercial and industrial premises, the Green Transit Corridor (comprising the Environmentally Friendly Transport Services, footpaths and cycle tracks) and other uses, and for construction of the proposed infrastructure works such as district distributor roads, local roads, revitalisation of existing channels, sewerage (including pumping stations), drainage (including pumping stations), water supply, landscaping, electrical and mechanical (E&M), and associated works.

 

The HSK/HT NDA development will be implemented in three phases, comprising First Phase, Second Phase and Remaining Phase development.  The First Phase development which comprises the site information and engineering infrastructure works under Advance Works Phases 1 and 2 and Stage 1 Works has commenced construction in 2020.

 

The HSK/HT NDA Advance Works Phase 3 and Stage 2 Works are collectively called Second Phase development (also known as HSK/HT NDA Second Phase Development – the Project).  The HSK/HT NDA Advance Works Phase 3 includes site formation and engineering infrastructure works for the site for Dedicated Rehousing Estate (DRE), residential and industrial uses and Government/Institution or Community (G/IC) developments.  It also comprises construction of engineering infrastructure works, including a primary distributor road, district distributor roads, local roads, drainage, sewerage (including pumping stations), water supply, landscaping, E&M and associated works as environmental mitigation measures and EM&A programme.  The HSK/HT NDA Stage 2 Works includes site information and engineering infrastructure works for the commercial, residential and G/IC developments in the proposed town centre around the proposed HSK Station, logistics, industrial corporate and technology zones village resite, and the remaining batch of multi-storey buildings.
