Mixed-Use Development Concept
One Sophia is planned as a mixed-use development where office, retail and residential uses are integrated within the same landmark address.

For investors, the mixed-use format can support multiple demand drivers — including office users, retail traffic, residential tenants, nearby students, city-centre workers and professionals who want easy access to Dhoby Ghaut, Orchard, Bugis and the CBD.
