The daughter of prominent Hong Kong businessman Peter Law Kin-sang has bought a luxury flat in Mid-Levels West following his sale of a Peak mansion in the city’s most expensive property transaction this year.

Winnie Law Wing-yin acquired a 4,710 sq ft (438 square metres) flat in tower two, phase one of The Legacy for HK$355 million (US$45.7 million), according to Land Registry records. The transaction was completed on Tuesday.

The luxury project at 8 Castle Road was jointly developed by Henderson Land Development and New World Development and opened for sales in September.

It features 172 flats, including a three-storey penthouse spanning over 12,000 sq ft – the largest new flat on offer in Hong Kong since 2013. The smallest unit in the building measures 834 sq ft.

The 11,451 sq ft house includes five bedrooms and five bathrooms, along with a 10,357 sq ft garden, a 3,035 sq ft rooftop terrace and parking spaces larger than the average home in Hong Kong. It also has a swimming pool and a jacuzzi.
