 To accommodate the construction of the Sha Tin to Central Link (SCL) depot by the MTR Corporation Limited (MTRCL), the Planning Department had suggested moving the Former Royal Air Force Hangar and the Stone House subject to further research by the MTRCL.Several District Councilors are concerned that the Old Pillbox and the Stone House were downgraded to pave way for the MTRCL's clearance of the site to build the SCL depot.According to Wong Tai Sin District Councillor Lam Man-fai, the "grading of historic structures is to evaluate their cultural significance, and not just looking at several stone houses."
