This thesis explores the design of a contemporary art museum using engineered timber construction, with a primary focus on the development of coordinated architectural and structural drawings. The project reinterprets heritage-inspired timber spatial principles through a modern glue-laminated timber structural system to achieve large open exhibition spaces and structural clarity. Structural layouts are developed in accordance with Eurocode design principles, ensuring rational load paths, serviceability performance, and material efficiency. Preliminary numerical verification using AxisVM confirms the feasibility and structural safety of the proposed roof system. The study demonstrates that large-scale timber buildings can be structurally safe, durable, and sustainable, combining historical precedent with contemporary engineering practice.
