Citi Design is a Brisbane-based Australian firm specialising in commercial and industrial plumbing design and trade-waste engineering, with over 20 years of experience in the field. Their core offering lies in integrating professional CAD-based hydraulic design services with on-site plumbing and construction expertise—thus providing clients with a seamless end-to-end solution rather than disparate design and build phases. Serving large-scale projects that demand compliance with regulatory authority requirements (such as stormwater drainage systems, sewer design, trade waste management, water-meter audits), Citi Design positions itself as a one-stop resource for the plumbing-design lifecycle—from early consultation through to construction execution. With a base in the Brisbane metropolitan region and capabilities to service Australia-wide locations, the company emphasises clarity, professional consultation, and efficiency in navigating both design documentation and onsite instalment constraints.
