13 arches 1055 mm apart, 391 pieces. Each half arch is laminated from four strips, two each side of the spacer blocks, and the ridge stands in the gap between the halves. Two rows of purlins each side; a purlin spans one bay, through the openings of the arches each side, and where two meet, one sits nearer the foot and one nearer the apex.
Drawn to fit, not calculated to carryThe checks prove the pieces go together. They say nothing about snow, wind or what the timber can bear: have the sizes checked before you build.
