Welcome to the website of “Long-term Strategy for Cavern Development – Feasibility Study”.

Hong Kong’s steep hilly terrain limits the growth of the urban areas. In response to the society’s needs for land to support our social and economic development, the Government is actively exploring the use of rock caverns as one of the innovative measures to expand Hong Kong’s land resources.

The Cavern Study aims to formulate a holistic, long-term strategy and approach to the planning and execution of rock cavern development to become a sustainable means of enhancing land supply.
