- GM30 current design visual
- Verification
- Room use exists in A20-02; visual geometry and finishes remain design interpretation.
Proposed GM30 lower-floor extension
Creating, moving, recovering and entertainment—one integrated level.
The existing lower-floor circulation remains the organising spine. The three marked zones test whether new rooms can be added around the approved building; they do not modify approved A20-01 geometry.

Excavation / working envelope
80–90 m²
Concept estimate
Excavated space ≠ finished internal area.
Working space beyond the future wall line may be required for formwork, waterproofing, external insulation, drainage and construction access. All areas are early estimates pending architect, RIB and surveyor verification.

Dora informs atmosphere, never geometry.
Every Dora Design room and image group is retained as project history. No item has been promoted to category A because room-by-room geometric correspondence with the later approved drawings has not been verified.

Future scene architecture
The room, source, status and material records are independent of the scene media. Verified 360 imagery, GLB / GLTF models or WebGL scenes can replace a concept image later without changing the approved-plan record.
