  • 1. Preliminary Planning and Design

    Starting a building project is an exciting journey, and we recognize that by the time you reach our team, you’ve already invested significant time and care into your vision. While we’re often the final step in a complex process, our priority is to transform your meticulously crafted vision into reality with care and clarity. We immerse ourselves in every detail of your project from its overarching purpose to the nuanced, personal touches that make it uniquely yours.


    Our process begins with an in-person consultation to explore your goals, priorities, and any non-negotiable details that matter most to you. This conversation is vital: we believe the strongest outcomes arise when your aspirations and our expertise are perfectly aligned.


    Once we understand your vision, we’ll guide the design phase with insight and precision. Whether you’re collaborating with your own architect/draftsman or leveraging our trusted network of designers, we’ll proactively identify opportunities to refine plans, solve challenges, and elevate the final result all while staying true to the original creative vision. Our goal is simple: to deliver a space that exceeds expectations, both functionally and emotionally.

Whether you’re modernizing a heritage home or expanding with a sleek extension, we’ll help you align every choice from flooring to lighting with your lifestyle and budget.

  • 4. Comprehensive proposal and documentation

    Once your renovation or extension plans are approved, we’ll partner with engineers, architects, and council specialists to secure all required building permits, consents, and compliance documentation. Simultaneously, we’ll craft your comprehensive building proposal, a tailored roadmap outlining costs, timelines, materials, and construction phases. This critical document typically takes 1-3 weeks to finalize, ensuring every detail aligns with your vision and local regulations.

  • 5. Contract Signing

    Next, we’ll schedule a detailed proposal review to walk through every aspect of your project. This collaborative session ensures we address any adjustments, refine timelines, and confirm that costs, materials, and design details align with your vision.

    Every step in the pre construction phase, including council permits, architectural drawings, and material schedules, adds value by safeguarding your investment and streamlining execution. Once you’re confident the plans reflect your goals, we’ll formalize the agreement with a signed contract. This marks the exciting transition from planning to breaking ground on your dream renovation or extension.

  • 6. Construction Begins

    Once construction commences on your renovation or extension, we’ll keep you informed and confident with fortnightly progress meetings and updates. Additionally, we’ll schedule check-ins at every major milestone—like framing, electrical, or finishes—to discuss next steps and ensure alignment on critical details.
