Front Left Wall Panel

v2 Gemini approved

Create the front left OSB/EPS SIP wall panel, 1453x122x2310mm. Include a spline joint on its left edge to mate with the corner post spline groove, and a vertical spline groove on its right edge for the door header. Base sits on the sole plate.

This component represents the front left SIP wall panel, incorporating a standard 1200mm section and a custom 253mm remainder to achieve the 1453mm target width. It features an integrated block spline protruding on the left edge for corner mating, and leaves a 22.5mm deep core groove on the right edge to receive the door header's frame spline.
