Front South Wall

v1 Claude approved

Create the front facade SIP wall, 2000mm length x 122mm width x 1856mm height (11mm OSB3 / 100mm EPS / 11mm OSB3). Include a 900x1878mm centered cutout for the door opening starting from the bottom edge. The bottom edge and top edge foam core must be recessed by 45mm deep x 100mm wide to form a rebate_spline connection for timber plates.
