Gerlofs and Poon confront a persistent methodological contradiction in neighbourhood research: urban change is intrinsically heterogeneous, yet comparison requires some degree of commensurability, replication and reliability. Their ‘aesthetic survey’ addresses this through a configurable suite of methods rather than a single evidential instrument. Cartographic, statistical, photographic, archival, historical, narrative and geospatial records are not collapsed into one register; they are coordinated within a repeatable field architecture capable of adjustment across Mexico City, Singapore, Hong Kong, Shenzhen and Guangzhou. The iconic idea is that methodological integration can preserve contextual difference while still producing comparative structure. Scale and territorial delimitation remain provisional, and neighbourhood boundaries can be revised as field knowledge accumulates. Time is equally variable, ranging from instantaneous alterations to cumulative transformation. The wider significance is methodological rather than stylistic: comparison becomes an infrastructural achievement, generated by carefully organising heterogeneous observations instead of assuming that pre-existing cases are naturally commensurable.
