Concrete Home Extensions in Melbourne

Modern house renovation and concrete home extension in Melbourne featuring seamless indoor-outdoor living and architectural design.

Old World Character Meets Modern Structural Integrity

Space to Grow. Design to Last. We deliver high-quality concrete home extensions across Melbourne, with a focus on established inner suburbs such as Brunswick West, Fitzroy North, Balwyn, Toorak and Essendon. Our fully integrated service covers everything from concept and architectural design through to construction, interiors, finishes and final handover.

Your Vision, Managed. From First Sketch to Final Finish.

Renovation and home extension process from concept design and drafting to finished construction using concrete and mixed materials.

Home extension is often stressful because there are too many people to manage. We act as your single point of contact, taking responsibility for the entire project.

Managing a residential extension can quickly become fragmented—separate architects, consultants, permits and trades all moving at different stages. We remove that complexity.

COAD88 CONCRETE operates as a full-service design and build company, delivering complete concrete house extensions under one team. From the initial concept through to construction and final handover, every stage is coordinated in-house.

We do not take on partial scopes or build from external plans. Each project is delivered as a complete process, ensuring consistency in design, documentation and construction.

  • Concept Design & Coordination: Development of the initial concept, aligning architectural design, structure and materials into a clear, buildable outcome. All architects and consultants are coordinated as part of a single process.

  • Design & Permits: We handle everything from layout planning to Council approvals and compliance, moving your project forward without the stress.

  • Structural Engineering & Approvals: All engineering input and required approvals are managed in-house, removing the need for separate consultants.

  • Materials & Selections: Guidance through all material and finish selections, balancing durability, performance and overall appearance to suit the project and budget.

  • Fixtures, Fittings & Equipment (FF&E): Complete supply and installation of cabinetry, appliances and lighting, delivered as part of the overall build for a consistent, well-finished result.

Materially Diverse. Concrete Focused.

Versatile Building for Modern and Heritage Homes

House extension featuring concrete, timber cladding, Shou Sugi Ban, Corten steel and brick used together in a modern design.

Every existing home brings its own constraints, proportions and character. Our work focuses on delivering concrete house extensions that respond to these conditions while introducing a clear, contemporary structure.

Concrete remains the primary material, forming the structural base of each extension. It is selected for its strength, durability and long-term performance. Where appropriate, it is combined with other materials to achieve a balanced and resolved outcome.

  1. Hybrid Construction: We seamlessly blend our signature concrete durability with timber, glass, steel, and traditional brickwork.

  2. Heritage Integration: Specialized in extending Victorian, Edwardian, and Mid-Century homes with modern, high-performing materials.

  3. Custom Aesthetics: Whether you want a raw industrial look or a warm, organic timber-and-stone finish, we have the expertise to deliver it.

Why Choose the COAD88 CONCRETE Team?

Managing a build shouldn't be your second job. We oversee the entire site—scheduling, trades, and quality control—so you don’t have to.

  1. Fixed Responsibility: If you have a question, you call us. We are responsible for every nail and every slab.

  2. Budget Control: Because we handle both the design and the build, we can keep a close eye on costs from the very beginning.

  3. Local Melbourne Knowledge: We understand local building styles and council requirements across Melbourne's suburbs, from inner-city blocks to larger family homes.

Every extension starts with the right foundation—clear thinking, resolved design and a coordinated build approach.
