Step-by-Step Guide

1. Place the main water base (canal) in the center-left area. Align its curved edges with visual guides, keeping it slightly to the top-right of the center for natural connections with bridge and island pieces.
2. Place the largest platform (lower-left island) in the bottom-left quadrant. Ensure its upper-right corner is near the water’s left edge and edges align with the visual grid for smooth snapping of lamp posts and curb pieces.
3. Place the Eiffel Tower and surrounding lamp posts on the bottom-left platform. Offset the tower slightly toward the lower-left of the platform and align lamp posts on the sidewalk between the road and platform edge.
4. Place the three mansard-roof buildings (cluster) on the central island and near the bridge. Ensure minimal road gaps for vehicles and align façades with road edges.
5. Place the bridge and the long promenade with trees in the upper-right to connect the central and top-right islands. Align promenades flush with building entrances for vehicle or pedestrian access.
6. Place the church/cathedral complex on the top-center island and add nearby houses. Ensure visibility of the promenade trees and path, and align house doors with paved walkways.
7. Place vehicles (buses, cars) on the roads and boats in the canal. Position vehicles flush with curb curvatures, ensuring no overlap with pedestrian zones, and align boat orientations with water ripples.
8. Add final props: crosswalks, stop signs, small trees, bollards, and street lamps. Ensure even spacing and no overlaps, forming a continuous curb loop for completion checks.
