About GCB

GCB Constructions has been built on its commitment and reputation to provide clients with the highest level of satisfaction and standard of finishes. Established in 1981, Greg Clark Building Pty Ltd, through growth, formed GCB Constructions Pty Ltd in 2011 covering South East Queensland and Northern New South Wales.

Our History

Over the years our business has grown from our founders Greg and Jenny Clark, to an organisation employing over 100 people, with offices in the Gold Coast and Lismore. Our mapped future growth will soon see us opening additional offices in Newcastle and the Sunshine Coast.

In the early days our workload consisted of a significant volume of refurbishment projects. These gradually became more challenging as our approach proved successful. Many of our earliest clients are still negotiating projects with us today.

Our forty-year legacy is one of our proudest achievements and is a true testament to our culture, operational mantra, and adaptability. This is maintained through our constant commitment and consistent delivery that exceeds client expectations.

Our Experience

As our organisation has grown, we have strategically recruited and supported our delivery teams with strong and capable leaders. These leaders have brought us to the attention of new client bases and subsequently, new market sectors, continually growing our portfolio of projects and expanding our relationships.

Over our forty years of constructing long lasting and landmark projects, we have learnt, evolved, and led the market with our collaborative, engaging, and nurturing approach.

Our large portfolio of projects and people enables us to deliver projects across multiple market sectors incorporating all attributes from heritage restoration to greenfield developments.

Our Difference

The past 39 years of trading profitably has allowed GCB Constructions to establish a strong balance sheet with assets to support its continued growth and expansion. GCB has self-funded this growth and has the capacity to deliver projects up to $120 million. This has ensured that we can deliver on our promise of innovation and quality across the continent, servicing both metropolitan and regional areas.

As a diversified and privately-owned construction company, GCB Constructions has a proud history of being able to nimbly adapt its service across many sectors to consistently deliver high quality projects to local and state governments and private corporations.

Our legacy of projects extends across the following sectors


Our team consists of over 120 skilled and highly experienced people, most of whom are long term team members. This enables us to ensure a consistency of delivery across all our projects. Every day we are supported by carefully selected professional subcontractors, suppliers and consultants.


We believe in working intelligently which means we are the first choice for clients who want to stand out from the rest with their projects. We understand what it takes to deliver a project on time and on budget, without ever compromising on quality.

Our knowledge and high-quality standards are solid, but our way of working is flexible. Every project is unique, but the same rigorous safety standards apply.

GCB’s key point of difference from many other building companies’ is the quality of our finished product.  We do not accept a mediocre finish; this is a key company value.

GCB Constructions is code compliant with the Australian Building Code and the various codes of practice in QLD and NSW, WHS codes of practice, Quality Assurance and Environmental standards.
