What our clients say

  • Within a very short space of time 21K Design Projects delivered a stunning layout that captured everything that we asked for. We had a plan developed on first-draft that is 99% of what we are now living in, which is a testament to the 21K Design Projects on how intuitive and ultra-efficient they were in interpreting the brief.”

    Adam & Kristy Roberts – Port Macquarie
  • “We would like to thank and personally recommend the team at 21K Design Projects. The way that they could actually draw exactly what we were thinking was phenomenal, bringing together exactly what we wanted but didn’t really know how to articulate.”

    Paul & Jacque Dubious – Melbourne
  • “Working with the 21K Design Projects team was effortless; they embraced my ideas and created design elements that gave my home presence and flair. The team delivered work of a quality you rarely see in business today, target timeframes were met and the drawings were produced as requested.”

    Deb McNaught – Coffs Harbour
  • “The quality of their work has hugely impacted the growth of my business, with new striking designs being undertaken all the time which are well received by our customers. The clear and exact dimensioning on the plans eliminates errors and our whole team benefits from this along with our trade’s onsite who have often given feedback about the quality of the plans.”

    Darrin & Joanne Thompson – Woolongong
  • “Building Designers who know what they’re doing, provide excellent advice, service, affordable and efficient turnaround times. I’d recommend them to anyone.”

    Jake Weldon – Gold Coast
