What Our Clients Say
Trusted by Homeowners, Developers & Visionaries
I’ve worked with Trish Arnoldi Interiors for over a decade and I have always been delighted. The quality they deliver is stand out and the professionalism and willingness with which each project is tackled is wonderfully refreshing! Trish is a talented decorator with a keen eye, and she is always appraised of current trends and full of sage advice, saving me many times from expensive and frustrating decorating mistakes! You can’t go wrong with Trish.
Trish has been my go-to interior designer for over 20 years, and she is nothing short of brilliant. In that time, she has transformed several rooms in my home, from complete makeovers to perfectly chosen paint colours—inside and out. She has created beautiful curtains, reimagined and reupholstered furniture, and brought fresh style and harmony to every space she’s touched. Every time, she delivers exactly what I envisioned (often better!). Most recently, she brought her incredible talent to my Early Childhood Development centre, a 450m² space that is now vibrant, fun, and bursting with life. The décor is playful yet practical, perfectly suited to young children while still reflecting my personality and vision. What I love most about working with Trish is that she gets me. She listens, understands my style, and then adds her own creative flair to produce something unique and beautiful every time. I could never have created the space I have today without her.
Our Story – Design That’s Personal
At Trish Arnoldi Interiors, great design is personal. It reflects your lifestyle, values, and the way you want to live — now and in the future.
My design journey began in the family business, Barristers Blinds, where I learned the craft of interiors and the importance of detail. From managing production for professional decorators to launching my own nursery décor brand, I’ve spent decades refining my skills and building a network of trusted suppliers and artisans.
Today, my focus is on creating timeless, elegant interiors for clients who value quality, care, and collaboration. Many of my earliest clients still work with me today — a testament to the trust and relationships we’ve built.
