Welcome to another episode of the Heritage Buildings Podcast.

Vincent Reed sits down with Mariachiara Faliva, accredited conservation architect and façade specialist, to explore the science behind historic buildings, material decay, and the investigative work required to understand why buildings fail. Drawing on more than 20 years of experience in conservation, diagnostics, and failure analysis, Mariachiara shares how studying chemistry for conservation in Italy led her into building pathology, laboratory analysis, and the study of historic materials. She explains why many conservation challenges stem from poor diagnosis and incompatible repairs, and why successful interventions begin with understanding how materials behave and deteriorate over time.

Mariachiara also reflects on her work investigating historic structures in New York, including early steel-frame masonry buildings and terracotta façades, before moving to London to specialize in building performance and façade engineering. She discusses the importance of balancing repair and replacement, the role of maintenance in preventing water-driven damage, and how tools such as WUFI hydrothermal analysis support informed retrofit decisions. Through projects including Tate Liverpool and the Barbican renewal, she highlights the value of early-stage investigations, data-led design, material reuse, and collaboration across disciplines to deliver more sustainable outcomes for historic buildings.
