A home is more than a finished space.
Cassa Interior was founded on the belief that a home is where life unfolds. Every corner, every material, every light source is chosen with intention — to make your space feel personal, functional, and timeless.
Based in Gading Serpong, Tangerang, we work closely with homeowners to bring their vision to life — from initial concept to the final detail.
