Assembly

Perimeter strip foundation for 8000x6000mm footprint, concrete strip depth 300mm, strip width 142mm, hollow ring under sole plates, placed at offset Vector(-142,-142,-300). Top face Z=0 bears SIP sole plates via M12 anchor bolts.

South eave wall, SIP-120 (120mm core,142mm total), runs through outer-to-outer, span 8000mm, height 2700mm. Two fixed windows 1800x1200mm sill 900mm at x=400mm,5000mm. Sole plate screwed to foundation; bevelled top plate (30 deg) bears south roof slope.

North eave wall, SIP-120 (120mm core,142mm total), runs through outer-to-outer, span 8000mm, height 2700mm. Three fixed windows 1800x1200mm sill 900mm at x=850,3300,5500mm. Sole plate screwed to foundation; bevelled top plate (30 deg) bears north roof slope.

East gable end wall, SIP-120 (142mm total), triangular apex, butted span 5716mm between eave walls' inner faces, eave height 2782mm, ridge height 4432mm at ridge x=8000,y=3000. Double patio door 1800x2100mm at x_offset 2250mm. Butts into south_wall/north_wall inner faces; apex bears ridge_beam end. ridge height 4432.1mm (duo-pitch gable end wall — this component MUST call .gable(ridge_height=4432.1) with this exact value; do NOT build a plain rectangular wall).

West gable end wall, SIP-120 (142mm total), triangular apex, butted span 5716mm between eave walls' inner faces, eave height 2782mm, ridge height 4432mm at ridge x=0,y=3000. Front door 1000x2100mm at x=2100mm; two windows 1200x1200mm sill900 at x=450,3800mm. Butts into eave walls' inner faces; apex bears ridge_beam end. ridge height 4432.1mm (duo-pitch gable end wall — this component MUST call .gable(ridge_height=4432.1) with this exact value; do NOT build a plain rectangular wall).

Double-bevelled LVL ridge board, 7716mm long x 90mm wide x 300mm deep. Each top face bevelled to 30 deg pitch bearing full underside of south/north roof slopes; arris meets panels' plumb-cut mitre. Ends bear on east_wall and west_wall gable apexes.

South SIP-120 roof slope (142mm total), ridge_length 8000mm, half-span 3000mm, pitch 30 deg, eave height 2700mm, eave overhang 400mm, rake overhang 300mm each end. Bears on south_wall bevelled top plate and ridge_beam south bevel face via structural screws.

North SIP-120 roof slope (142mm total), ridge_length 8000mm, half-span 3000mm, pitch 30 deg, eave height 2700mm, eave overhang 400mm, rake overhang 300mm each end, low drainage. Bears on north_wall bevelled top plate and ridge_beam north bevel face; plumb-cut mitre meets south slope at ridge centreline via structural screws.
