OCON Building Group is a Melbourne-based residential builder specialising in high-end new homes, major renovations, and architectural extensions. We deliver custom-built homes designed to suit modern lifestyles, established streetscapes, and premium inner-suburb living.
Our team works closely with homeowners, architects, and consultants to manage every stage of construction — from planning and approvals to completion. With a strong focus on craftsmanship, structural quality, and refined finishes, we build homes that are made to last.
Our work spans Melbourne’s inner, bayside, and eastern suburbs. Each project is tailored to the home, the block, and the local character, whether it’s a contemporary extension, a full renovation, or a custom new build.
Located in bayside Sandringham, this project focused on a ground-floor extension and outdoor integration. The design complements the coastal setting while creating additional living space suited to relaxed, modern family life.
