The present work explores the relationship between architectural design and biogas production from household food waste and other disposable materials. It investigates the necessary parameters for adapting domestic architectural designs to accommodate biogas production plants. To achieve this, the study initially delves into commonly known biogas key parameters and selects the most relevant ones to be used as design guidelines for architects. It also examines the architectural structures of biogas digesters implemented worldwide to identify suitable prototypes that can be readapted or redesigned for Egyptian domestic environments. The paper also addressed some issues regarding required workspace calculations for the biogas roof installations, including bearing loads on roof slabs. The paper further explores the architectural characteristics of different types of Egyptian residential buildings to allow for the design of a domestic biogas plant prototype tailored to each specific building type. Additionally, it addresses the need to understand the architectural characteristics of Egyptian residential buildings and the design of the biogas plant prototype, highlights the constraints of Egyptian residential buildings to optimize the design, and proposes spatial configurations for biogas plants in various types of residential buildings in Egypt. Under the discussion section, the paper introduced some proposals regarding safety concerns and cost analysis.
