    When to use

    Corner units with two exterior walls — typically upper floors of multi-unit buildings. View-side properties where view changes direction at the corner. Balconies serving multiple rooms — master bedroom on one side, en-suite or sitting room on the other; or living and dining both opening to the balcony.

    Each segment: 60-144 inches long × 36-72 inches deep. Asymmetric: often one segment longer than the other. Total area: 25 sq ft (small corner) to 100+ sq ft (full wraparound).
