Over the past two decades, the concept of heritage has been significantly broadened, with an increasing number of scholars viewing it not as a set of static objects with fixed meanings but as a social process consciously endowed with commemorative functions through human creation. This research illustrates and empirically supports this perspective through a case study. Initially, the paper reviews the development of the heritage concept through the literature review and elaborates on the idea of “heritage as process”. Subsequently, it examines Singapore’s enriching exploration and successful implementation of heritage conservation, particularly since 2000, when the local government shifted from preserving historical buildings to a comprehensive conservation strategy that embraces a sense of place, identity, and memory and encourages a bottom-up participatory approach. Finally, this paper takes the transformation of the century-old townhouse at 141 Neil Road in Singapore as its focus. After being renovated into an urban architectural heritage conservation laboratory, the house has gradually become a place of heritage on Neil Road by training professionals’ construction skills, transforming its function, introducing technological explorations, and enhancing public interaction. This process has developed the abilities of heritage conservation professionals in desktop research, reuse design, and practical construction skills while simultaneously promoting community participation and heightening awareness of heritage conservation among local residents. Through daily practices, this historical townhouse gradually became a place of heritage on Neil Road, exemplifying the research theme that “heritage is a comprehensive and dynamic practice encompassing social, cultural, and technological dimensions”. From being preserved for renovation in 2020 to being approved as a “Heritage Show House” by the Urban Redevelopment Authority (URA) in 2023, the case of 141 Neil Road offers a new perspective in the heritage conservation field that “heritage is always in the process of becoming, rather than a constant given”.
