SHA designs with a keen sense that architecture is a temporal art – unfolding in time and interacting with the rhythms of nature and human activity. Holl often invokes time as a fourth dimension of design, shaping spatial sequences and envisioning buildings in the context of past, present, and future. Time is also considered in terms of daylight and seasons: strategic apertures and light scoops in SHA buildings mark the passage of hours, like a modern sundial in inhabited form. “Haptic time,” where weathering materials like copper or corten steel register time’s patina, enrich a building’s story with age. Underlying this, is a respect for deep time: SHA’s additions to historic structures are conceived in dialogue with history, projecting a timeless quality that will carry forward. By embracing time’s layering – from conceptual “forking” to natural aging – SHA creates architecture that is not static, but a dynamic participant in life’s temporal flow.
