After the Hong Kong Government renamed Castle Peak to Tuen Mun in 1974, the estate was renamed San Fat Estate in honour of Chan Yat-sen and Lau Wong-fat, prominent figures in Heung Yee Kuk.
[5] The estate was home to the Hoh Fuk Tong Primary School, which later relocated to Lung Mun Oasis.
[2] The 1996 "Five-Year Redevelopment Programme" announced that the estate would be demolished in 2000-01 due to its age, and to free up land for the construction of the Tuen Mun station of the West Rail.
It was rebuilt above ground level to integrate it with the new West Rail station and renamed Tuen Mun stop in 2003.
Following completion of the station, the former site of the estate was used as a temporary parking lot, and as a public transport interchange.
