WHAT OUR HAPPY CLIENTS SAY

Spannenberg & Son Pty Ltd
Excellent
4.8
I asked for a quote to repair a loose soffit, and Patrick was incredibly helpful and friendly. After inspecting it, he explained that it only needed a few nails and fixed it on the spot. He even mentioned that we were former customers and kindly took care of it for us. Patrick was professional, honest, and very obliging. Excellent customer service—I highly recommend them.
We had a very positive experience with Spannenberg and son builders. From their design and complying development through council to the actual renovation was efficient and completed on time. We especially appreciated the organization of the tradesmen as the job progressed. There was no wasted time. Communication from the company was good. We were able to stay living in part of our house during the renovation. All tradesmen were polite and helpful.
We couldn’t be happier with the building extension works carried out on our home. From start to finish the entire process was smooth, professional, and completely stress-free. Every member of the team who came to our home was fantastic to work with friendly, respectful, and highly skilled. Their attention to detail was outstanding and it’s clear they take great pride in the quality of their work. A special thank you to Scott (Director and Brand Manager), who supported us from the very beginning. His expertise and guidance, gave us great confidence throughout the project. We would also like to thank Patrick (Project Manager) whose day to day leadership and dedication ensured everything ran like clockwork. The project was completed on time with excellent communication throughout. Any questions or concerns we had were addressed quickly and we always felt well informed at each stage. The quality of the workmanship exceeded our expectations and we are absolutely delighted with the final results. We would not hesitate to recommend their services to anyone considering building or renovation work. Thank you again for a job exceptionally well done!
We recently completed a kitchen and living room renovation with Spannenberg & Sons, and couldn’t be happier with the result. From the very beginning, Ben’s leadership and early engagement with James during the concept design gave us confidence that our project was in safe hands. Our block is not an easy one — with more than 50 steps up to the living room — but the team handled it with professionalism and care. Sam, our Project Manager, was exceptional throughout. His calm approach and intelligent decision-making meant that even when the occasional unexpected issue arose (as happens in every build), the stress was kept to a minimum. We lived in our home during the renovation and were impressed by how respectful the entire team was. Mitch, Connor, Lockie, and the other trades ensured our home was looked after, cleaning up each day and doing everything possible to minimise dust. The quality of the finish is outstanding. Our new kitchen and living space feel better than we imagined, and we are genuinely grateful to the Spannenberg team for bringing our vision to life. We would not hesitate to engage them again for our next renovation.

When we first started this journey, we were at a crossroads—do we sell up and move, or stay and build up? After weighing up the costs, the disruption of relocating, and the hefty stamp duty and removal costs that come with buying a new home, we decided that a first-floor addition made far more sense. Not only was it significantly more cost-effective, but it gave us the flexibility to create exactly what we needed in the home and location we already loved. We engaged Spannenberg and Sons for the job, and the experience from start to finish has been nothing short of exceptional. We undertook a first-floor extension along with some ground floor modifications, and the result has completely exceeded our expectations. The workmanship was second to none—every detail was finished to the highest standard. The team was professional, friendly, and incredibly well-organised throughout the entire process. A huge thank you to Scott and Blake for your thoughtful design and concept work. You brought our vision to life in a way that’s both beautiful and practical. Thank you also to Nigel, who expertly managed the project and kept everything running smoothly. We were lucky to have such talented carpenters on the job—Ryan, Tom and Mark, all part of the Spannenberg team, brought exceptional craftsmanship and attention to detail to every part of the build. The subcontractors chosen by Spannenberg were also outstanding. A special mention to Neil from Mumford Electrical, who went above and beyond to ensure our home was not only functional but also safe and seamless. Jace’s tiling work is beautiful, and Josh’s painting was meticulous—he even embraced my outlandish red front door without hesitation! Jake and the team from AB Interiors delivered stunning wardrobes that are both functional and stylish. And thank you to Westglass for the perfect finishing touch with our shower screens. The entire project ran to a tight schedule and was handled with care and precision. I absolutely love my new home and am so grateful to the entire team for making the process smooth, professional and genuinely enjoyable. I can’t recommend Spannenberg and Sons highly enough. Choosing to renovate instead of relocating was the best decision we could have made.
I almost never give reviews, so the fact I am doing so should speak volumes to the positive experience we have had with our renovation. Initially, the standout areas that sent us to Spannenberg was that they design AND build. We have been stung in the past engaging a designer, only to be stuck with an expensive design that was not feasible or possible to build. We knew with Spannenberg that whatever they designed, they had to and could build. The other key area that sold us was Scott. Scott was a friendly and approachable face, for whom nothing seemed too much trouble. That was important for us as we knew we would make changes along the way and we wanted to be comfortable doing so. Which as it turned out we did several times, and each time it was no trouble and in fact welcomed by the team as they too wanted the best result. I am a fairly hard marker, and living in the reno meant that I was able to see every aspect of the build as it was completed. It was a big job, and it would be unrealistic to expect everything to go exactly to plan or be perfect. But Pat and his team were always on the ball to ensure a high standard was set, and Pat always made himself approachable to raise any concerns along the way. Although I am sure I was a nuisance and pain in the butt from time to time, Pat never once made me feel that way. Pat ran the job to the exact day of completion - which I still cannot believe. He loves a good spreadsheet and his analytical approach clearly works. When need Pat jumps on the tools to keep things moving and clearly is a very talented tradesman. The team Spannenberg has shows that they hold their staff to a high standard. High quality work, but with a smile and always approachable. Dan was leading hand on site. Always smiling, incredibly polite, very skilled tradesman. Luke is a young but hard working apprentice, usually smiling but if he isnt its because he is focussed on what he is doing, eager to do a good job. Pete is a rarity - old school hard worker, brick laying skills that should be considered an artform. You cant tell where the old bricks were and the new ones now are. We are actually disappointed the renovation is complete we enjoyed the process and company of the guys on site so much. I cannot recommend the team highly enough.
The team was professional from start to finish. Ben took the time to find the right solution for us to get more living space. They solved a complex seepage problem successfully and also replaced a structural beam neatly to give us more head room in our basement. Then they rebuild our deck from the ground up, larger and added a roof. They have a fantastic work ethic and work to a high quality standard. Blake the project manager worked very hard to bring the project to completion. We went with Spannenberg and Son because we knew they would get everything done correctly. We found them via Hope 103.2 radio.
We are thrilled with our new home thanks to Spannenberg. From start to finish they listened to our needs, provided great advice and recommendations to design and build our expanded new home. We added a first floor, a new deck and new kitchen but it feels like we have a whole brand new home. It wouldn't have been the same without Blake (our project manager) who worked tirelessly with his team and various contractors to ensure old blended with new and everything was done to such a high standard. Not only that but they work FAST! Both neighbours and friends couldn't believe how quickly they progressed the job as we were back living in our home after 5 months. Thanks again to Ben, James and especially Blake who brought our dream home to life - we wouldn't change a thing!

From the moment we discovered Spannenberg on Facebook to their final day at our property putting on the finishing touches, the Spannenberg team have been nothing but professional and amazing. Scotts ability to put our vision into a plan and onto paper, and then Blakes ability to transfer these ideas into house plans at the start of the project gave us so much confidence to commence our renovation with them. We weren’t going outside of the existing footprint, but we needed many walls taken down to create an open plan kitchen/living/dining, new walls put up to create a new bedroom, media room and mud room, replace all the windows and remove weird Grecian pillars from our front porch. Also a special mention to our amazing new skylight and our oversized window with louvres looking into our backyard which they sourced and installed. Once we got started, we could not fault Patricks attention to detail, and his seamless management of the project timeline and his team ensured everything stayed on track. His approachability meant we weren’t afraid to ask questions or for help on the most menial of product selections. The building team of Mark, Ryan and Pete who worked so hard through rain, shine and extreme heat to produce high quality finishes and a completed project, while ensuring it was tidy at the end of each day was so appreciated. The project finished on time barely even going a day off schedule and getting us into our property in time for Xmas. To say we love our new home and layout is an understatement. Our vision for our home came to life and has exceeded our expectations. This is thanks to the amazing work of the Spannenberg team and we could not be happier and would not hesitate to recommend them for any project you are considering.
Ben and his team replaced 28 windows at our house in Gordon. I grossly underestimated the scale of the job. Considering they were touching every room in the house they were neat and tidy, polite and worked tirelessly over the weeks. I would recommend as a key consideration (besides price) is the relationship that you need to have while they work in your home.
We just completed our second renovation project with Spannenberg after they did a brilliant job on the bathroom a few years ago. We were so glad to work with Scott and his team to bring our dreams to life. Our project manager Paddy has great communication and attention to detail. It was so easy to communicate and the quality of the workmanship is outstanding. We could not be happier with the end result and would highly recommend for anyone looking for a quality builder.
We had our renovation done by Spannenburg and Son in 2019, and they've been fantastic. They've come back a few times to fix paintwork and a leaking vergola, always without any hassle. Their prompt response and dedication to quality are impressive. I highly recommend Spannenburg and Son to anyone looking for a reliable renovation team—you'll feel confident knowing they'll take care of any issues well after the job is done.
I recently had a renovation completed with new kitchen, butlers pantry, new WC, new main bathroom & new ensuite bathroom, all project managed & layout designed by Spannenberg & Son, with Spannenbergs as the principle trade builder and other sub-contractors completing the work in a professional and timely manner, I'm really impressed by the finish of everything ! I choose Spannenberg because of their good reputation and previous work done on other projects within the Macarthur area. This was my first renovation and i was daunted by the process of doing major work on our family home and the cost of it. All my fears were allayed by the great work by Scott, Patrick and the Spangenberg team. Patrick project managed the site from day one until the end, organised & handled the work schedule, material and booking of appointments with other trades. Patricks experience, politeness and professionalism left a lasting impression on me, he is definitely worth his weight in gold. I have no hesitation in recommending Spannenberg & Son and i am happy & content that i choose them.
Thank you to Scott, Patrick and the whole team for an amazing job on the second story extension! The build is amazing in quality, the attention to detail is unmatched and always making sure things are done correctly and to a standard that they absolutely should be proud of. Very easy to work with and bless their patience with my mother. Thank you all so much! We absolutely love it!

Spannenberg and son recently did renovations on our house, we got our front awning, out back pergola and a few other items done. The quality of work is great, the paint works are exceptional. We are very happy overall with the look and quality. Thank you
So professional, so friendly turned up exactly when they tell you they will, kept in touch with updates regularly, did an amazing job, I will definitely recommend to anyone looking to get work done!! They made this experience so easy. I will absolutely use their services again!!!
Amazing services and communication. Glad to have chosen them as our home extension builder. They guided us from start to finish and everything in between to ensure we knew our options and choices. I would definitely recommend them to anyone looking to build or extend their home.
We had a great experience working with Scott, Patrick and everyone at Spannenberg & Son. The communication was fantastic. We knew what was happening and when at all times. It was all done to a high standard with professionalism and a smile. Thank you.
We’ve worked with the Spannenberg team on the northern beaches for many years and it’s great to see other like minded trades with high work ethics and consistently high quality results
We had spoken with a few builders about building a 1st floor extension with all of them wanting to sell us a standard floorplan, and then Scott and his team at Spannenberg & Son were recommended to us. From the very first meeting with Scott, he took the time to understand what we wanted and came up with a design to meet that. Patrick did a fantastic job managing the build in awful weather, while Dan, his team, and the other trades, finished the job to an impeccably high standard. Communication was fantastic, nothing was ever too hard, and everyone regularly on site is super friendly - the type of person you'd be happy to invite into your home. We cannot recommend them enough.
So pleased with the work recently completed by Spannenberg & Son. Small job carried out without a hitch. The whole team involved were amazing, prompt, helpful & top quality work.
Just had my bedroom renovated. Quick turn around from qoute to completion, at a reasonable price! Scott was great with getting it all explained and into motion for me. Nigel was also a really good project manager. Will definitely use them again in the future!
