Every school sets its own portfolio rules, so the school’s instructions override any general advice. Many programs ask for a portfolio at entry, some only after a first-year review, and some do not require one. A missing statement on a program page does not mean none is needed.
What to show
Select a small number of strong pieces that show how you think and how you make: observational drawing, sketchbook pages, concept boards, simple models, photography of spaces or objects, and any drafting or design projects you have done. Quality and clarity matter more than volume.
Show process
Include early sketches and iterations beside finished work. Reviewers want to see how an idea developed.
Presentation
Keep a consistent layout, photograph physical work in even light, label each piece with a short description and your role, and follow the stated format, page limit and file size.
Originality
Include only your own work and credit collaborators. Do not present a client’s or a classmate’s project as yours.
Prepare your statement and your questions
Write a short statement explaining why you want to study interior design. Check whether an interview, assignment or prior-degree requirement applies.
Keep track
The Admissions and portfolios page has a checklist that stays in your own browser.
