Design Development & Coordination
Design development is the stage where your approved concept becomes a resolved, buildable scheme. At Dadirri Architects, our design development service refines layout, structure, services, materials, and detailing so that every decision is locked before documentation and pricing begin. This is where design coordination and consultant coordination happen in earnest, ensuring all disciplines are aligned and the design is ready for the next phase.
For Melbourne homeowners and developers, a thorough design development phase is the most effective way to reduce surprises, control costs, and achieve a build that matches your expectations.
What Is Design Development?
Design development bridges the gap between concept design and construction documentation. During this phase, the approved schematic design is developed in detail: structural systems are confirmed, services are routed, window and glazing types are selected, and materials are specified. The developed design resolves the “big four” decisions that drive cost and programme: structure, services, windows, and materials.
Design development also includes design coordination with your consultant team. We review engineering, energy, and landscape proposals against the architectural design to identify and resolve conflicts before they reach the drawing board.
Our Design Development Process
Step 1Design Review:
We revisit the approved concept with you, confirming any changes to the brief or budget since schematic design.
Step 2Structural Resolution:
We work with the structural engineer to confirm floor systems, wall types, foundations, and any special structural elements. Consultant coordination begins at this stage.
Step 4Material and Finish Selection:
We present material options with samples, pricing guidance, and performance data for your approval.
Step 3Services Integration:
We coordinate hydraulic, electrical, and mechanical services routing, ensuring they integrate cleanly with the developed design.
Step 5Design Coordination Workshop:
We bring all consultants together for consultant coordination, reviewing the developed design, resolving conflicts, and confirming scope.
Step 6Sign-Off:
You review and approve the design development package, giving us a clear mandate to proceed to construction documentation.
When You Need Design Development
Design development is the necessary bridge between concept approval and construction documentation. You need design development when your schematic design has been approved and you are ready to resolve the details, you want to confirm structure, services, and materials before committing to documentation, you need a cost check against a developed design before proceeding, or your project involves multiple consultants who need to coordinate their work.
Skipping or rushing design development leads to incomplete documentation, costly variations during construction, and a build that may not match your expectations.
What You’ll Receive
Our design development deliverables include refined floor plans, sections, and elevations at increased detail, preliminary structural coordination drawings showing the developed design, services routing plans (hydraulic, electrical, mechanical), material selections with samples and specification notes, three-dimensional views of key spaces showing the resolved developed design, a cost plan update in coordination with a quantity surveyor or builder, and a design development report summarising all decisions for sign-off.
These documents give you, your builder, and your consultants a clear, shared understanding of the project before documentation starts.
Documents and Drawings Produced
During design development, we produce developed design floor plans, sections, and elevations, material and finish sample boards, 3D views of key internal and external spaces, a design development report with decision log, consultant coordination mark-ups, and a cost plan summary.
Typical Timelines
Design development typically takes four to eight weeks for a residential project in Melbourne. The timeline depends on project complexity, the number of consultants involved, and the pace of material and finish selection decisions.
Larger or more complex projects with extensive consultant coordination may take eight to twelve weeks. We will provide a clear programme at the outset.
Frequently Asked Questions
-
Typically four to eight weeks. We will provide a timeline at the outset based on your project’s complexity and the consultant coordination required.
-
All major material, colour, and product selections should be confirmed. We guide you through the sequence and timing of each decision.
-
Minor refinements are expected. Significant changes to layout or scope may require a return to schematic design and will be discussed openly.
-
We recommend a cost check during design development to confirm the developed design is tracking to budget before documentation begins.
-
Design development resolves the design and locks decisions. Documentation translates the developed design into construction-ready drawings and specifications.
