Interior design isn't just "decorating" — it requires technical skills (CAD, 3D modelling, materials, lighting design, building codes), business skills (vendor management, costing, client communication), and aesthetic judgement. Formal education compresses 5+ years of trial-and-error into 2-4 structured years. At INSD Ahmedabad our interior design students complete 6+ live projects before graduation — residential, retail, hospitality and office — building both the skills and the portfolio that get them hired.
