What you study	Architecture Design Environmental Studies History	Computer GamesInformation ServicesSoftware Engineering	Computer Science General or Integrated Engineering Information Technology
What it is	You study how to design and restore buildings while minimizing environmental impact, combining architecture, history, and ecological design. This program emphasizes conservation of existing structures and sustainable materials and methods, setting it apart from general architecture programs that focus mainly on new construction. It suits students interested in heritage preservation and green building who want hands-on experience through co-op placements.	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	You study how to design, build, and maintain software and computer systems. This program covers programming languages, algorithms, data structures, and how computers work at a fundamental level. If you choose the co-op stream, you'll alternate between studying and working at tech companies, giving you real professional experience alongside your degree.
