What is a Bachelor of Interior Design (Commercial)?

The Bachelor of Interior Design (Commercial) is for the rule-breakers ready to shake up the spaces we live, work, and play in. This degree arms you with the skills and experience you need to design the ever-changing environments of retail stores, hotels, nightclubs, restaurants and workspaces.

Explore the practical elements of designing commercial interiors – branding, lighting, sustainability and materiality – to create environments that inspire clients and users. You’ll learn how interior design strategies are developed and executed, while picking up industry essentials like contract management, cross-disciplinary teamwork and professional design practice. With cutting-edge software and 3D modelling, you'll learn how to turn your wildest design ideas into reality, from costing to construction. This degree is about pushing boundaries, challenging trends, and redefining the future of commercial interiors.
