What happens after the design and tender presentation?

 

After the design and tender presentation from the $990 Design Your Happy Place session, the project moves from early clarity into decision and refinement. This is the stage where you assess the concept direction, review the preliminary cost position, confirm whether the project aligns with your goals, and decide how to move forward. For many Illawarra, Sutherland Shire, and Southern Highlands homeowners, this is the moment the project starts feeling real rather than theoretical.

 

Assessing the concept and cost direction

The presentation gives you a bespoke floor plan concept, 3D renders, a preliminary cost range, and an approval pathway recommendation. The first thing that happens is a conversation about whether those outputs are aligned with your expectations. For some clients the direction feels right and the project is ready to progress. For others there may be refinements needed — adjusting the brief, scaling the specification, or reconsidering part of the design. That is completely normal.

 

Moving into detailed design and approvals

Once the concept direction is confirmed, the project moves into more detailed design development, structural engineering input, selections planning, and approvals. The approval pathway — whether DA through Wollongong City Council, Sutherland Shire Council, or Wingecarribee Council, or CDC through a private certifier — shapes the timing of this stage significantly. EBG manages the approval process as part of the integrated project scope.

 

Contract preparation and construction

After approvals, the project moves into HIA building contract preparation, final selections sign-off, and construction commencement. EBG uses HIA building contracts with EBG's custom special conditions. Construction on a custom home across the Illawarra and Sutherland Shire typically runs 12 to 18 months from commencement through to handover.
