The challenge: floor outlines do not always line up.
The upper floor projects beyond part of the ground floor. Aligning the two drawings only by their bounding boxes would move the shared staircase and structural elements. Instead, both floors were placed in one architectural coordinate frame.
An opening needs to be an actual opening.
Windows and doors are cut through the wall geometry rather than drawn as dark rectangles on a solid wall. Partitions are specified separately from room labels. This keeps open-plan living areas open while giving enclosed rooms a route in and out.
The roof and stairs need a spatial check.
The pitched roof follows the main volume and intersecting gable. The staircase connects the floor levels, with a real opening in the slab above it. Cutaway controls expose these relationships without requiring the entire roof to remain in the way.
Outdoor context has clear limits of accuracy.
The plot boundary was traced from a CAD polyline. Surrounding buildings provide approximate context and are not presented as surveyed structures. The pool and terraces help explain how the house connects with its outdoor spaces.
Geometry and illustrations remain separate.
The interactive model supports layout checks. An optional illustrative gallery explores materials and atmosphere. This development example includes no invented client endorsement, sales result or promise of construction accuracy. Visitors can inspect the actual model and judge its relationships for themselves.
