The essay argues for an accumulative approach to architectural heritage, viewing buildings as temporal objects shaped by adaptation and patina. It critiques preservation and demolition, advocating additive conservation that extends building life, preserves authenticity, and supports sustainability, allowing architecture to evolve with society.

The essay examines architectural heritage as a dynamic, accumulative process rather than something to be preserved in a fixed state or erased through demolition. It critiques traditional conservation, preservation, and restoration approaches, rooted in nineteenth- and twentieth-century theory, for prioritising aesthetic uniformity and historical idealisation over adaptability and continued use. Drawing on theorists such as Ruskin, Viollet-le-Duc, Brandi, and Stiegler, the text explores tensions between authenticity, aesthetics, historical value, and utility, linking society’s treatment of ageing buildings to a broader cultural discomfort with ageing itself.

The essay proposes understanding buildings as temporal objects that embody time through layers of material, patina, and intervention. These accumulated layers are framed not as damage but as valuable records of social and technological change. By adopting an additive and adaptive approach to conservation, buildings can have their lifespans extended while retaining visible traces of their histories. This accumulative model supports sustainability by reducing material waste and carbon impact, aligning conservation with environmental goals such as net-zero carbon targets.

Ultimately, the essay argues for designing and conserving architecture with future adaptation in mind, allowing buildings to evolve with society and form an accessible and continuously growing heritage rather than static monuments.

The physical form of the essay is printed on tracing paper, with each category—such as text, image, and title—placed in the same position, allowing an accumulation of these layers throughout the publication and replicating the accumulation of heritage described within the essay.
