60 Years Dedicated to Construction

GPZ takes its initials from the company’s founder George P. Zachariades who was born in 1916. In the early 1950s he began his contracting activities in Cyprus setting the foundations for what was to become a successful business which would be carried on for 3 generations to date.

G. P. Zachariades Overseas Ltd. was formally established in 1956, at a time when Cyprus was in great need of infrastructure development. Undertaking projects for the Government of Cyprus, the British Bases and various private clients, the company began specialising in dams, hangars, jetties, highways, bridges, irrigation networks, power stations, as well as government buildings and residential apartment blocks.

In the early 1970s, following the substantial growth of the company, the vision was to expand GPZ’s operations beyond Cyprus. After exploring countries in the Gulf, Bahrain prevailed with its welcoming community, business-friendly environment and good quality of life.

GPZ was registered in Bahrain in 1976 as a Grade AA Civil Engineering and Building Contractor, also undertaking interior fit-out works and mechanical and electrical installations. Some of the first projects completed were the British Bank of the Middle East, the Immigration Headquarters, Yateem Centre and the French Embassy. The company very quickly began establishing an exceptional reputation for its high quality workmanship and timely completions.

In 1986, after the sudden passing of George P. Zachariades, his son Stefanos G. Zachariades took over the leadership of the company. GPZ continued to develop its impressive track record, providing professional management for a distinctive level of service and playing a leading role in upgrading building standards and raising the quality benchmark in Bahrain’s construction sector. Today, with 60 years of commitment to excellence, GPZ is an established and mature business with a work ethic and name synonymous to consistency, quality and trust.
