Jacob and Darcy majorly extended and renovated our Ocean Grove home to transform it into not only our dream home, but also our beautiful retirement property.
They were extremely accommodating of all our ideas and requests, ensuring that whatever we wished to include in the home, they made it work.
Both Jacob and Darcy were easy to liaise with, respectful of our ideas and helpful in guiding our choices. They were also readily available via phone or in person when we needed to speak with them.
We cannot recommend H&M Building Group highly enough for anyone seeking a quality build or renovation to an existing home.

We would highly recommend Jacob and Darcy from H & M Builder's Pty Ltd. We recently had them create a backyard blitz and nothing was too much trouble.
We love the retainer walls they built and our front fence is a real feature of our home. They project managed our backyard blitz from start to finish and best of all within budget and timeframe. The advice they provided created our dream backyard.
No job was too big or too small. If you are looking for quality, trustworthy and professional builders then look no further. Jacob & Darcy are your go to guys!
Anne & Daniel
I can't recommend Jacob and Darcy from H & M Building Group enough! We hired them for a big renovation and extension on our home, and the experience was fantastic from start to finish. Their team was not only professional but also super easy to work alongside. They took the time to understand our ideas and offered some great suggestions that made everything look even better than we'd hoped.
Throughout the whole project, they kept us updated on the progress and any changes, so we always knew what was going on. They stuck to the timeline, and the budget we agreed on was exactly what we paid - no surprises.
Every time we now walk through our renovated space, we're just so happy with how it turned out. The quality and attention to detail are amazing. If you're looking for a trustworthy, skilled team to handle your renovation or extension, definitely go with H & M Building Group. They genuinely care about doing a great job!
Glenn & Kate
We are incredibly happy with Jacob and Darcy’s work to renovate our kitchen, laundry and bathroom. They listened to our needs and helped us land on a design that maximises the functionality of our small family home. They kept the job on schedule and within budget, and kept the rest of the house clean. We love our new spaces and the quality of the finish. Jacob and Darcy are lovely to work with and I would highly recommended them.
Emma
H & M Building Group recently built a horse shed (stables, float bay, tack room and feed room) for us, and we couldn’t be happier with the result. From the start, Jacob and Darcy were fantastic to work with—professional, easygoing, and always willing to listen. They made the whole process seamless, allowing us to make adjustments along the way to ensure the final product was exactly what we needed.
The quality of their work is outstanding, not just in the structure itself but in the details. Everything was completed neatly, and the site was left in great condition. Their team of tradesmen, such as plumbers, were just as professional, ensuring every part of the project was finished to a high standard. The work was completed on time and within budget.
The landscaping for this job was tricky but they made it work and could help us with the vision we desired. The end result is a space that’s not only functional but a pleasure to use.
Communication was excellent throughout, and we always felt like we were in good hands. We couldn’t be happier and highly recommend H & M Building Group for their skill, care, and attention to detail.
