Services
Concept Designs
Developing tailored architectural concepts through client collaboration. We create initial sketches and diagrams to explore spatial relationships and functional layouts. Our process includes iterative client reviews to refine design direction while considering budget constraints and regulatory requirements. This phase establishes the foundation for all subsequent design development.
3D Modeling
Creating detailed 3D BIM models for design evaluation. Our digital modeling services enable clients to experience spatial relationships before construction begins. This technology supports informed decision-making through interactive walkthroughs and material visualisation, ensuring alignment between client expectations and final deliverables.
Architectural Plans
Preparing comprehensive documentation for regulatory approvals. We produce detailed floor plans, elevations, and compliance tables required for council DA or private certifier CDC submissions. Our documentation meets Australian Building Code standards while maintaining design integrity throughout the approval process.
Construction Documentation
Developing detailed construction specifications and drawings. This phase involves coordinating with structural and MEP engineers to ensure technical compliance. We produce documentation packages that facilitate accurate tendering and guide construction teams through complex building requirements while maintaining design intent.
Construction Oversight
Providing on-site supervision during construction. We conduct regular inspections to verify workmanship quality and compliance with approved plans. Our team coordinates contractor communications, resolves design-related issues, and ensures final inspections meet specified standards and client expectations.
