This project explores the nature of housing, studying and exhibiting an archive of core samples as part of a wider geological collection of Charles Lapworth. The archive is nestled within the context of the existing Blackfriars chapel ruins and the empty Madras College. The cabinet is a miniature architecture inhabiting the uninhabited husk of Madras. Sitting beyond the excavated pathway, facilitating the holding of the existing Madras facade whilst forming a structure to cradle the archive of core samples. Steel fins derived and genetically similar to those of the kist, a previous tectonic exploration, provide a supporting structure to hold the archive, upon which a timber framed cabinet is held. Viewers enter this subterranean world below the cabinet and pass through a blackened steel ramp running under the core samples suspended from a tower. An experience which mimics the process of extracting rock samples from the ground, entering underground and being brought to the surface through the proposed architecture.
