In September 1991, the building, along with 15 other properties in Mountbatten Road, was planned to be gazetted for conservation by the
Urban Redevelopment Authority (URA). In 1999, the bungalow was sold to businessman Ang Koon San, where he envisioned it to be a "multi-generational home for his four children and their families" consisting of a common family wing and three separate wings. involved the replacing of damaged roof tiles, the revarnishing of the timber floors of the interior, and the restoration of the timber partitions. All of the original timber windows, each of which had around 40 parts, louvre parts and doors were disassembled piece by piece stripped of old paint, sanded down and reassembled. Glass from Australia was used to replace broken panels. Damaged fragments of the decorative plastic elements of the capitals of the columns were recreated and recast.
