About Us & The GCG Difference
Guy Construction Group (GCG) is a licensed and reputable building company based in New South Wales, proudly servicing Sydney’s North Shore, Northern Suburbs, and surrounding regions. Our projects span the Hornsby, Ku-ring-gai, Parramatta, and The Hills local government areas, with broader capability extending across the Greater Sydney region.
We deliver high-quality construction, renovation, and remediation services across the residential, commercial, hospitality, insurance, education, and strata sectors. Known for our professionalism, problem-solving mindset, and attention to detail, we have built a reputation as the builder who gets the job done, especially when others say it cannot be done.
We do not just build, we solve problems. We are the team people call when others walk away. Whether it is a tight-access terrace, a fourteen-storey apartment with no lift or crane access, or a storm-damaged property that requires urgent structural attention, we specialise in turning complex and challenging jobs into safe, compliant, and high-quality results.
Services
At Guy Construction Group, we provide a complete range of building and renovation services across residential, commercial, strata, education, hospitality, and emergency response sectors. Whether you’re planning a new renovation, managing a facility upgrade, or need urgent repairs, our team delivers professional, high-quality results with clear communication and dependable service.
Building Better, Together
Our success comes not only from our construction expertise but from our ability to coordinate and deliver complete end-to-end solutions. We work with a trusted network of licensed trades and professional services, including electricians, plumbers, tilers, roofers, carpenters, concreters, engineers, certifiers, building consultants, and specialist contractors.
This network allows us to respond quickly to project demands, deliver trades in the correct sequence, and maintain workmanship that consistently meets or exceeds Australian Standards.
We manage every stage of the project lifecycle, from planning, documentation, and trade scheduling to compliance checks and final handover. Our team works closely with engineers, certifiers, and clients to ensure every aspect of the job is well planned, safely executed, and fully aligned with industry regulations and your expectations.
We also take pride in working respectfully and professionally in occupied homes, businesses, and schools, minimising disruption wherever possible while maintaining clear and proactive communication.
