Nova Stairs

What Nova Stairs does

Nova Stairs generates stairs with stringers and railings that follow real building practice — fast, exact, and ready to detail.

Key features

• Real timber, not tinted plastic — oak, pine and ash each carry their own photographic texture, scaled to real size, with the grain running lengthwise along the tread, down the rake on the stringer, and end-grain on cut faces
• Straight, L, U, winder and spiral — winder treads fill the turn all the way to the inner stringer, with no gap where the stair changes direction
• Stairs with stringers — complex geometry in under 0.1s
• Code-aware railings (regulation spacing) with wood, glass, wrought-iron and stainless-rod variants
• Cuts its own floor opening through every storey the stair passes, with lined reveals
• Stringer covers tread ends at the top; newels run past the stringer
• English or Norwegian panel — switch at any time; it remembers your choice
• Adjustable rise/run and dimensions
