Oscar Design & Construction Mission Statement:


" To deliver a Top Quality Project, with a consistently strong level of service to all clients. "




"I am grateful that I have started my career back in 1999 working on design and construction of Sydney's finest landmark projects such as Walsh  Bay redevelopment, a $600 Million project located at Hickson Road Walsh Bay. This project included luxury mix-used residential and commercial high-rise apartments with marinas, the refurbishment of bond stores, and infrastructure works. Pfizer Head office is a $45 Million project located at North Ryde and other Sydney-based low to high-rise residential and commercial projects.

These larger tier-one companies and major projects that I worked on provided me with significant skills and propelled me later to start my own design and construction company in Sept 2006 which is located in Norwest Business Park. Since then my company has designed and built various residential and commercial projects which I am very proud of. 

My business goal is to continue providing a high level of service, quality and accomplish the best possible design and construction solution to all my clients and stakeholders no matter the size of their project".
