In their words
“Studio del Castillo is the Melbourne interior architecture and design studio of creative director Penny Del Castillo, trading as In Design International.”
Studio del Castillo is the Melbourne interior architecture and design studio of creative director Penny Del Castillo, trading as In Design International. Founded in 2010, it is a multidisciplinary studio creating experience-led interiors for homes, hotels and commercial environments.
The studio brings together interior architecture, decoration, furniture thinking, material selection and hospitality awareness. Its approach is practical: beauty lasts longer when it is supported by good planning, clear priorities and disciplined execution. Function, flow, adjacencies and service requirements are resolved before aesthetic decisions become fixed, and the work is designed to welcome people, guide behaviour and keep working long after handover.
