Photorealistic architectural 3D rendering. Camera located on the lower property (Owner A), positioned exactly at X = –6.00 meters, elevation 0.00 m, with a horizontal camera height of 1.20 m above ground, matching the eye level of a seated person. The camera looks perfectly horizontally toward the east, capturing the median boundary wall and the upper property. Foreground: Visible portion of the lower parcel includes the edge of the covered porch at X = –6.00 m, the grass strip between X = –6.00 and X = –2.00, and the buried swimming pool of Owner A between X = –2.00 and X = –5.00, at elevation 0.00 m. The pool water is calm, with realistic reflections of the afternoon sun. A seated human figure is present in the porch, but only partially visible from behind due to the camera position. Median boundary: At X = 0.00 m stands a perfectly vertical reinforced concrete retaining wall, 2.00 m tall, measured from elevation 0.00. The wall is smoothly plastered and painted matte white on the Owner A side. On top of the wall, from elevation +2.00 to +3.00 m, a 1.00 m tall black metal safety railing is installed, fully covered with dense natural brezo providing 99% opacity. The wall and the brezo form a continuous visual barrier reaching exactly 3.00 m in height. Upper parcel (Neighbor B): Behind the wall, at elevation +2.00 m, a compacted horizontal terrace extends from X = 0.00 to X = +3.00 m. At X = +3.00 m begins the infinity-edge swimming pool of Neighbor B. The pool water level is Mehr sehen
