A proposal to build two 42-storey blocks on the North Point harbourfront has been opposed by residents who claim air flow would be severely restricted by the project. About 20 representatives of the residents met Planning Department officials yesterday to express concerns over the Henderson Land Development plan to build the blocks in King Wah Road next to a 60-storey hotel being developed by Cheung Kong (Holdings). A committee member of the owners' corporation of nearby Harbour Heights, Fung Shu-shum, said the buildings would block air flow from the harbour. 'There is no way that air can get through three high-rises standing so close to each other,' he said. 'The hotel development has already started. The ventilation will be far worse if the Henderson project is also given the green light.' Mr Fung also said Henderson had not addressed traffic problems. 'The area is already very congested,' he said. The Town Planning Board decided in January to defer the application and seek more information from the developer. The Planning Department said the development was not incompatible with the surrounding area. A Henderson Land spokeswoman said it had taken into account the concerns in deciding the height of the buildings. She also said space would be left between the two buildings to let air through. There would be 50 metres between the two buildings and between the development and Harbour Heights, and 30 metres between the development and the Cheung Kong hotel.
