About_GDP Interior Design

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 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


“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 Diploma Arts (Interior Design and Decoration) from leading design institute RMIT, and is a member of the Design Institute of Australia (DIA) and Kitchen Bathroom Design Industry member (KBDI).

Giulianna’s industry experience includes designing independently and in partnerships with high profile Australian designers and building firms. In 2003, Giulianna established her own practice in Watsonia Melbourne, concentrating on residential renovations, new builds and decorating. 

In between family pursuits and work, Giulianna is a visual 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.

After a career in the healthcare sector, Nancy studied Interior Design & Decoration at the International School of Colour and Design (Dip Int D & D), and then Kitchen & Bathroom Design with Designer Training Australia (Cert IV). She has since been working in the industry as a Kitchen and Joinery Designer.


Whilst adept with all aspects of interior design, Nancy’s specialty is in kitchen design. Ensuring that the hardest working space in the house is both beautiful and functional is a challenge she adores. At home Nancy renovates, wrangles the kids and spoils the sausage dog!
