Less than a third of the existing buildings at Gillman Barracks will remain standing after the area is transformed into a new housing estate in the future, based on a recent environmental impact assessment (EIA) and heritage study released by the Housing & Development Board (HDB) on July 10. The heritage study, conducted by conservation consultancy Studio Lapis, assessed all 86 buildings in the compound known as Gillman Barracks. The existing buildings are spread out across seven clusters in a 40ha plot of land. The most evocative heritage building that will be spared is the original block on Alexandra School in Preston Road, which was constructed in 1939. The building sits on the highest hilltop within the area and currently houses the Preston Campus of the ISS International School. Meanwhile, three British-built colonial era buildings will also be kept. They consist of the former regimental headquarters of the Singapore Combat Engineers (Block 6), the services canteen and social club (Block 9), and the old sergeants’ mess (Block 22)....
