Interior Design Degree

Transforming space. Collaborative learning.

Interior designers improve the functional efficiency, safety, and appearance of interior space. They are familiar with building codes and accessibility standards, and they can read blueprints. They decorate, choosing colors, lighting, furniture and other items.

You’ll learn how to analyze space, understand its intended function, and create a plan using industry technology. You’ll practice presenting your plans to clients. You’ll know how to communicate with architects and contractors. These skills open an array of careers in the interior design industry.

The first two years of the Interior Design program and the Architectural Studies program share a common curriculum. This strong base increases your career versatility. Additionally, several of the upper-level technical courses share a common curriculum. This creates a collaborative and interdisciplinary atmosphere for both students and faculty.

We believe in hands-on learning. Our facilities include a fully-equipped wood shop, digital fabrication lab and large scale printy capability. You can also put what you've learned into practice and compete in national competitions. SIU students have placed in the Steelcase NEXT Design Competition National Top 10 in three of the past five years.

“What I love about this program are the people. Everybody is so helpful and supportive, we have all become a big, happy family. My professors have all been very encouraging and helpful through everything and have pushed me to become the designer that I am today.

—Caitlyn Cathcart, winner of the 2017 Steelcase NEXT Student Design Competition

Your personal design studio.

Course work within the Interior Design program focuses on studio-based learning. This provides knowledge of design and the design process in a work-lab setting. Studio courses at the first-year level may have as many as 25 to 30 students in each section. Upper-level studio courses generally have a range of 20 to 15 students.

You'll have your own studio space beginning your junior year! Our Studio Culture Policy ensures that the studios are productive work environments. This helps students cultivate the professional conduct expected in professional practice. All students must adhere to these policies.
