Office workers in Admiralty will lose one of their favourite lunchtime hangouts for the next few years, when Harcourt Garden closes to make way for construction of the Admiralty MTR station extension. The garden, which is located on top of the future extension, would be closed from early next year until 2015, the MTR Corporation said yesterday. But an elevated garden would be restored after construction is completed and its usable area increased by 70 per cent, said Peter Leung Man-fat, design manager of the MTR's South Island Line. The new Admiralty station will be a major interchange with two additional lines - the South Island Line and the Sha Tin-Central Link. After construction is completed in 2015, the total area will be more than doubled, from 9,000 square metres to 20,000 square metres. The platforms serving the new lines will be linked to the existing platforms by a series of escalators, and Leung said it would be a three-minute walk between the old and the new platforms. The extension will have six floors, and on the bottom will be the platforms of the South Island Line. On top will be the platforms for the Sha Tin-Central link. The extension will be covered by a large glass pane that will allow daylight to enter, and will include more than 30 escalators. 'The new lines will be able to attract some passengers who are now using the Tsuen Wan line. Admiralty station will not be more crowded,' he said. Construction would be designed to minimise disruption. Despite the MTR's reassurance that Harcourt Garden would be restored and there were no plans to add commercial elements to it, some office workers still lamented the loss. Wong Sze-mei, who regularly has lunch in the garden, said she would now be forced to dine indoors. 'As an office worker I already spend too much time indoors. It would be a loss if I cannot have lunch or simply stroll in the park, just to breathe some fresh air,' she said.
