The Hidden Infrastructure of Construction Materials

While wood offers a short-term sustainable alternative to concrete and steel, owing to its lower carbon emissions, concrete and steel are favored for long-term sustainability considerations. However, integrating adaptable rooftop configurations, particularly through prefabricated modules, into construction practices can enhance sustainability beyond material choices alone. Through a comparative analysis of wood, concrete, and steel, particularly in the context of constructing Accessory Dwelling Units (ADUs), this thesis explores the potential for holistic sustainability, encompassing not only ground-level construction materials but also innovative roof additions to elevate environmental performance.
