What Our Clients Say

Aaron’s effort and consideration at quoting stage was outstanding! He took the time to find out what we wanted, what our budget was and gave us options and alternatives to get the best outcome for us and his quote was by far the best we’d received. That then set the tone for the entire job. Aaron and his team were professional, friendly, and punctual and if there were any issues we were aware of them straight away and had complete confidence they would be taken care of without any stress on us. We highly recommend Seaside Building & Design to anyone for any build, big or small, and will definitely be contacting Aaron again for any further work we want done.

Daniel & Krystal Oliver

We embarked on to build our dream and ‘forever’ home. That dream has just become our family’s reality and we love it. Thank you to the awesome Seaside Building and Design team. Led by Aaron, their work was of the highest standard! The respect and care they constantly offered our family during the whole process was one of the highlights for us. They fully appreciated the pressure on our young family and made sure they did all they could to support us. We are super glad we chose Aaron and his team. They have become more like family and I know we have made lifelong friends with all the Seaside crew.

Henry & Anissa Rajendra

We recently had Seaside complete an extension to our home. From the planning stages through to completion, Aaron was very helpful and generous with his time, talking through our options and giving recommendations. The Seaside team was always courteous and helpful and their attention to detail was great, they were flexible with changes during construction, and they were always keen to make sure we were happy with how things were going. We are very pleased with the quality of their work and love the new space!
