Structural Engineering Services in Cooranbong, New South Wales

“We have been working with Simon & Peter from Additional Concepts for almost a decade now and they have certainly mastered reliability, consistency and top notch workmanship! We frequently deal with their customers and the common denominator among all their clients is the satisfaction and peace of mind they share. If you're doing extensions, new builds or renovations, then we can not recommend Additional Concepts enough, they are professional, honest, have excellent work ethic and importantly, are extremely friendly and fun to work with.”
