Architecture- 4 Jun 2026
I recently worked with this structural calculation engineer for a project that required precise drawings, and I couldn’t be happier with the outcome. The calculations were spot-on, and the drawings were clear and detailed, making the process seamless with my builders. Not only was the quality top-notch, but the pricing was fair and transparent. Communication was excellent throughout, and they delivered on time. Highly recommended!

Hard Flooring- 29 Dec 2018
Giuseppe and his team are top level professionals able to give qualified advice and real expertise. In renovating our art gallery, they showed real old-time mastery from the beginning. They not only helped us study the most suitable solutions for the features of our place both for the flooring and the walls painting, but also showed amazing precision and care in carrying out the whole renovation project by applying the renowned knowledge of Italian master masons. While other builders had cursorily told us that any laminate would be good, the one that Giuseppe and team suggested us was selected by considering both the resistance to the clomping and the desired aesthetic result. Also, they adopted all the special arrangements needed to prevent the wood floor from bulging and lifting. They suggested us the type and the colour for the skirting board, making the gallery even more refined. The works were terminated in the estimated time and the fantastic result in terms of elegance, sophistication and safety has been possible thanks to the reliability and attention to detail of Giuseppe and team. We were so satisfied that we decided to hire them for all the other works needed (ceiling painting, walls painting, positioning of the anti UV film in our windows, enforcement and lifting up of the electrical track for the lighting system). All these works were completed with mastery and are still contributing to fascinate all the visitors at the gallery!

I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend
