Huffing and Puffing: A New Language for Straw Bale Construction

Abstract

Situated in the Hauts-de-France, a region in France grappling with a severe housing shortage, this student housing project services the capital of the region, Lille, a prominent student hub, and its neighbor, Roubaix. In addition to the Nord's industrial history, the Hauts-de-France is renowned for agriculture, being France’s second-largest producer of straw. Straw bales, an agricultural byproduct, are load-bearing modules, exceptional insulators, and when used as a building material, a renewable resource drawing down carbon. Pairing the availability of the material with the region’s housing needs, the project capitalizes on straw bales’ structural, thermal, and ecological properties to expand their use in construction beyond the one-story home and develop multi-story student housing. It seeks to generate a structural and material expression unique to the straw bales to bring greater spatial and sensory diversity to extant, repetitive student housing typologies. As the discipline becomes increasingly concerned with its environmental and social impacts and shifts towards engineering new materials and building systems, there is a unique opportunity to reconsider natural materials long used in construction and address disciplinary misapprehension surrounding biogenic materials such as straw. The project diverges from trends in digital and material fabrication to embrace this hyper-local, renewable byproduct and unite ecological, architectural, and social aims.
