About_GDP Interior Design
DO IT ONCE - DO IT WELL

At GDP Interior Design, we sort through the vast choices on offer today to match the right products and selections to your project. We focus on supporting you with informed decisions along the way.

Things that are important to us:

  • Journey; improving renovation and building experiences for our clients and builders

  • Functionality; cleverly utilising space and scale, maintaining proportion and comfort

  • Beauty; creating balanced, sensory pleasing spaces with longevity

  • Knowledge; appreciation of raw materials and understanding craftsmanship

  • Approach; keeping a sense of artfulness, colour, creativity and fun

With over 20 years of industry experience, we don’t subscribe to one-style-suits-all approach. We believe our project outcomes should reflect you and your environment; not your design firm!  Our gallery of projects reflects diversity, just as our clients do. We take pride in that no two projects are the same.

Giulianna del Popolo

PRINCIPAL DESIGNER & ARTIST

“I have always loved houses and homes. I have very strong sensory memories of the materials, textures and patterns I grew up with. As a child I would draw floor plans and create vignettes everywhere I could! Establishing my career in Interior Design was so obvious; I have never looked back.”

Giulianna has an Interior Design and Decoration qualification from leading design institute RMIT. In fact (some 30 years after graduating) she now teaches in this course as a sessional casual! She is an active member of the  Kitchen Bathroom Design Industry member (KBDI) and is highly connected within Melbourne's design scene. 

After exploring various roles for Melbourne Designers and high end builders, Giulianna established her own home practice in 2003. In 2016 GDP Interior Design Studio opened in Watsonia, concentrating on residential renovations, new builds and decorating.  Giulianna is pleased to work collaboratively, and quality partnerships have been formed with local architects, builders and designers since then.

In between family pursuits and work, Giulianna is a fine artist and brings this artistic filter to her interiors, even offering custom commission artworks. She is passionate about all things colour, design, and creating spaces to feel good about!
