NJK Property Group is an award winning company with a reputation for consistent innovation at the highest level of design.


We have been marketing and selling properties on behalf Nick Vlouhos and his company NJK Property Group for close to 10 years.

Nick’s work is always exemplary and his attention to detail always brings a wonderful product to market. All of the homes we have sold on his behalf maintain a level of excellence and his creditability with the product resonates with high resale values we achieve.

I have no hesitation in recommending and referring to anyone who wishes to consult with Nick on their future home of development and I would be more than happy to discuss with any potential client looking to appoint NJK Property Group to build for them.

Greg Mavridis, Chase Property Group

I am a licensed Real Estate Agent with over 30 years experience. I was approached by Nick to market and sell his 2 properties in Jones St Ryde. I was fortunate enough to witness the construction from commencement to completion. The intensity of quality control and attention to detail was something I have never evidenced in my Real Estate career. The feedback from potential buyers was that the quality of building and materials used was faultless. Needless to say, both properties sold for close to record prices for the area at that time.

Keith Hillard, McGrath Real Estate

NJK Property Group was engaged to undertake the complete ground up construction of our new designer home from it’s conception through to a turnkey handover. Throughout the entire process their no problem nothing too difficult attitude not only produced a spectacular home but actually turned a complex, detailed design into reality that we are proud to show off. This is evident from the regular comments we receive from complete strangers that cannot walk past the home without stopping to marvel at the detail finish. Anyone can build a house but there are very few that can build a masterpiece which we now call home.Big thank you to the team at NJK Property Group and I look forward to our next project together

Mr James Pahis DE, JP, Datalec Services Pty Ltd

When it came to building our luxury house, we had a very specific design, build and finish that we were after. We had met with a few building companies prior to meeting Nick and the first thing that impressed us was the honesty and the attention to detail that Nick puts into his projects. It only took one meeting with NJK for us to decide that Nick had the capability and experience that was required to build our dream home.

Throughout the entire process, Nick maintained total control over all aspects of the build. From managing 3rd parties to contractors and us as owners, Nick completed everything on time and within the complex design requirements. Nick takes immense interest and pride to ensure each task is completed to a perfect finish. We can not recommend the team @ NJK highly enough.
