For projects that need a longer compact run, the S8N provides a stable, straight timber staircase in Craftsmans Pine. The on-page configurator helps you dial in rise, going and pitch in line with Part K principles (target ≤ 42°), shows 2R+G in real time, and calculates total plan length including nosing overlap and riser thickness—so you can check fit before ordering.

Layout & sizing

• Straight flight: 9 risers / 8 goings

• Rise per step adjustable 180–220 mm

• Overall width (strings): 600–1000 mm

• Total plan length calculated live (includes nosing overlap + riser thickness)

Timber specification

• Strings: 32 mm EdgeLam Engineered Pine

• Treads: 22 mm EdgeLam Pine

• Risers: 12 mm plywood as standard (upgrade to Pine; thickness auto-set by width)

Typical applications

Ideal for lofts, mezzanines, garage conversions and split-level spaces where a straight, made-to-measure timber staircase gives the cleanest layout.

Compliance note: The configurator flags pitch and 2R+G for guidance; final compliance depends on installed dimensions and site conditions.
