Having met with a number of builders before deciding to go with MJS Construction, we felt comfortable with them right from the start. Their approach, attention to detail and genuine interest in our project really stood out.
One of the things we appreciated most was the communication throughout the entire build. It's rare to come across a business, particularly in the building industry, that puts so much effort into keeping its clients informed. We received regular updates, always knew where things were at and what was coming next, and were never left wondering what was happening. It made the whole experience so much easier and gave us real peace of mind.
The project ran smoothly, everything stayed on schedule and the quality of the finished townhouses is fantastic. We're genuinely thrilled with the end result.
What really sets MJS apart is that they don't just deliver a great finished product, they also make the entire building experience a positive one. That's not always easy to find.
We really can't speak highly enough of the team at MJS. They've been a pleasure to deal with from beginning to end, and we'd happily recommend them to anyone looking for a quality builder.

From the conceptual start of our vision to our impeccably finished family home, Jeff and his team at MJS have been an absolute delight to deal with. The quality of the finish far exceeded our highest expectations. Jeff was totally invested in our build right from the start, the professionalism and care never wavered throughout the build. He wasn’t just out to get the contract but was genuinely interested in delivering what he promised, with exceptionally high quality workmanship. Jeff and his team take pride in their work. The project was finished punctually despite its complexity and on budget with all variations costed very fairly and transparently.

The communication about what was happening and the schedule ahead was always clearly explained. All queries were always promptly addressed, nothing was ever left hanging. The tradesmen were respectful at all times, not just to us but to our neighbours as well. The work site was always impeccably tidy.

Jeff is a reliable, honest and highly detailed driven builder who delivered for us an exceptionally well built and finished family home. We have full confidence in Jeff and his beautiful team and highly recommend him to be your builder. Thank you Jeff for your patience, care and expertise in delivering to us our wonderful family home. If we were ever to build again, we would love to have you once again.

After-sales experience

It has now been almost six months since we moved into our home. In addition to the amazing experience we had with MJS and the team throughout the build, Jeff still calls me most Wednesdays to make sure everything is going well.

Like all builds, there were a few minor fixes needed, and the MJS team were always on top of getting those little issues sorted quickly. They even happily repaired a few things we had accidentally damaged after moving in.

It is one thing to have an amazing experience during the build, but I am even more impressed by the level of service and care we received after handover. Jeff is exceptional, and he has built an incredible team that is clearly focused on making sure the entire experience is first class.

A special shout out to Jeff, Josh, Jessie, and all the other contractors — thank you so much.

Outstanding experience building with MJS Construction Group. They brought our Cheltenham townhouses to life a lot earlier on time and to an incredibly high standard. Communication was clear and concise throughout, and their project management led by Jeff and his team was flawless.

Anyone who has built before or engaged trades for a Project in this part of the world is much aware of the stress and pitfalls that comes with it. Building with Jeff makes this build process immensely enjoyable and wanting to build again. That, is probably a great testament to him and his team’s approach to building.

If you are after a reliable builder who delivers premium results, look no further.

I had an outstanding experience working with Jeff and the entire MJS team on completing our two townhouses. From start to finish, the project was handled with professionalism, reliability, and genuine quality care.

Jeff runs a tight, well-organised operation. His team was consistently on time, respectful of the schedule, and clearly committed to delivering high-quality workmanship.

Jeff kept me informed at every stage, was always responsive to questions, and made the process feel smooth and stress-free.

I recommend Jeff and MJS to anyone looking for a builder who delivers on time, maintains excellent quality, and communicates every step of the way.

Building our home with Jeff at MJS Construction Group was the best decision we could have made.

We recently completed our home in Oakleigh with Jeff and his team, and overall couldn’t be happier — right from initial meetings, through to tendering and then the build process itself. It was a perfect experience.

I approached Jeff after completing plans with another builder and from the onset he was as invested as we were - we contacted other builders in the area who were not interested for various reasons (a blessing in disguise). One thing that differentiated Jeff from the others was he was straight into the details to make our home a reality, no sales pitch, no nonsense, no bullshit gimmicks. Building a new home in today's environment can be daunting for many reasons, but never had we felt more comfortable. A lot of this comes down to the well-drilled process Jeff's team follows from project to project- everyone at MJS knows their role.

An example of this by was the level of detail in the documentation. Everything is discussed, documented, reviewed, signed-off - you know exactly what you are getting. That said, there was always opportunity to tweak along the way if required and Jeff never said no. When a problem surfaced Jeff always proposed and delivered a solution. One thing to note is if you build with MJS you have to be prepared to be committed and invested - don't expect to sign a contract and hear from them 40 weeks later like how volume builders operate. It's hands-on throughout.

Jeff was easily accessible through weekly calls, site meetings and constant correspondence. Phil (site manager) was fantastic too - always there and available to lend a hand. Jeff is on the ball all the time, he knows exactly what is happening each day right down to the finer details. He treats the build as if it's his own.

Our final result was a beautiful high-quality built home that exceeded our expectations in every way.

If you're looking for an honest, transparent and reliable builder that delivers a stress-free quality build, MJS are for you.

Thanks to Jeff, Danny, Phil, Dillon, Belinda and Rebecca.

Building our knockdown-rebuild with MJS Construction Group was an experience defined by confidence, clarity, and genuine care. From the very beginning, it was clear we were partnering with a builder who values quality, respect, and long-term relationships — not just delivering a finished house, but creating a home with purpose and longevity.

Working with Jeff was exceptional from start to finish. From our first interaction, his communication was clear, proactive, and deeply reassuring. He took the time to genuinely understand our vision and guided us through what was a complex design and approval process with patience, confidence, and integrity. Jeff’s calm, respectful, and highly professional approach set the tone for the entire journey. Even with a constrained site and detailed council requirements, everything was handled seamlessly, with clear explanations and thoughtful problem-solving. His attention to detail and considered design input elevated the home well beyond our expectations and made the entire process feel smooth, controlled, and genuinely stress-free.

We were very specific about wanting expansive spaces combined with intelligent, highly usable design, and the outcome is a true reflection of the team’s expertise. Meg’s design work was outstanding — her drawings captured our vision beautifully while balancing functionality, aesthetics, and practicality with remarkable precision. Every challenge was approached with a solution-focused mindset, and we were consistently presented with well-considered options that enhanced the overall outcome rather than compromising it.

Jeff is an outstanding leader, supported by an impressive and highly capable team including Meg, Belinda, Daniel, Joel, Josh, Guy, and the many skilled trades working behind the scenes. Together, they delivered a home that not only met our expectations, but elevated them to an entirely new level.

Belinda’s patience and refined guidance throughout the selections process made what can often feel overwhelming an effortless and enjoyable experience. Daniel and Joel’s calm, composed approach when incorporating our requested variations contributed greatly to a smooth and positive build journey. Josh’s thoroughness and meticulous attention to detail gave us complete confidence during the final stages leading up to handover. Guy’s landscaping deserves special mention — his expertise and creativity transformed our outdoor spaces into a tranquil, elegant retreat that perfectly complements the home.

MJS delivers far more than a build; they deliver a considered, premium experience defined by professionalism, transparency, and exceptional quality. We are absolutely thrilled with our home and would highly recommend Jeff and his team to anyone seeking a builder who truly excels in both execution and client care.

Thanks Jeff and Team!

Choosing the right custom home builder is a huge decision, and after completing our build with MJS, we’re convinced we chose the best builder in Melbourne. Jeff and his team are professional, highly experienced and genuinely invested in delivering a quality home. Communication was exceptional —Jeff updated weekly, answered every question clearly and proactively resolved issues before they became delays.

The workmanship is outstanding. Our final inspection was flawless, with every detail already picked up the team before we even noticed it. The project finished ahead of schedule, the site was always clean and organised, and neighbours constantly commented on how respectful the team was.

We were so happy with the entire experience that we’re already hoping to build with MJS again.

If you’re searching for a reliable, honest and detail-driven builder who delivers a stress-free building experience and exceptional results, we highly recommend MJS.

MJS deserve a 10 out of 5 review — just an amazing and truly stress-free experience. Building with MJS Construction Group was incredible from start to finish. Jeff and the team delivered exactly what they promise on their website — on time, on budget, with excellent communication and attention to detail.

Led by Jeff, and supported brilliantly by Daniel, Belinda, Rebecca, Dillon and Josh, the whole process was seamless. The project finished ahead of schedule, the quality is outstanding, and every detail was managed with care.

A huge thanks also to the tradies who clearly take pride in their work. Special mention to Guy (landscaping) and Jessie (electrician) — nothing was ever too much trouble, and their workmanship was first-class.

In a time when you hear so many negative stories about the building industry, MJS are a shining example of honesty, transparency, and reliability. We’re beyond thrilled with our new home and can’t recommend them highly enough.

A1 Builder- Professional – Committed – Reliable.

My wife and I wanted to knock down our old house and build 2 townhouses. We knew what we wanted to do and after seeing and talking to more than 15 different Builders we learnt a lot from each of them and knew who could or couldn’t do it for us.

We met Jeff from MSJ Construction Group. After the initial meeting with Jeff, we knew that Jeff was the Builder for us. A straight shooter that won’t waste his time or our time, if Jeff says that he could do it then he will do it. A professional that’s on top of everything, from start to finish. A man that works tirelessly to achieve a common goal. And of course, a great team behind the scenes that do fantastic work and always willing to listen to our needs and get things done efficiently.

Because Jeff only takes in enough projects that he knows he can look after, he looks after our houses with great care and dedication. He made the process smooth and seamless throughout the construction process (the houses were completed 2 weeks earlier than scheduled).

Great work Jeff and the team at MSJ Construction Group. Thank you for the beautiful houses and your dedication from start to finish. Highly recommended.

Jeff built a dual occupancy for us in Bentleigh. The finishes and attention to detail were first-class. We received a very good outcome at our first auction, and everyone who saw the building was very impressed with the build. We enjoyed working with Jeff who was as interested in the whole process as we were. He suggested all of the luxury finishes and helped with every step of the process. Very importantly he was always available to talk. Every Wednesday he rang me to let me know where we were up to, and if I ever had any questions and was unable to speak to him immediately he always rang back as soon as he could. In fact I can't think of bad to say. Thanks Jeff and you deserve 5 star rating.

Fantastic people to deal with and great quality work!
