Left-Hand Double Winder Staircase with Handrail (S3W3W33N) – Trade Range

Left-Hand Double Winder Staircase with Handrail (Trade Range – S3W3W33N)

This Left-Hand (L/H) double winder staircase is designed to create a full 180° turn in a compact footprint using a double winder turn (two consecutive 3-tread winder turns). It’s a practical solution for loft conversions, attic access, and projects where space is limited but you still want a proper staircase with a safe, solid handrail and balustrade.

Unlike “stairs only” listings, this model is supplied as a complete stairs and railings package, making it easier to plan your project, match components, and achieve a consistent finish.

What’s included (Handrail & Balustrade Specification)

• 90mm Pine square newel posts

• 32mm Pine square balusters

• Pine STHR handrail

• Pine STBR baserail

• EdgeLam Pine strings

• 22mm MDF treads

• 12mm Plywood risers

Key benefits

• Stairs and railings in one kit – ideal if you’re searching for handrails for stairs or banister rails for stairs with the staircase.

• Compact 180° turn layout – double winder design helps when a landing won’t fit.

• Clean, traditional look – square newels and square balusters suit modern or classic interiors.

• Configurable to your space – select your rise and width, with calculations set up to keep the stair comfortable and sensible.

Options

Bullnose Entry Step (+£50)
Add a bullnose entry step for a smarter start to the staircase and a more premium first impression — ideal where the staircase is visible from a hallway or open-plan space.

(You mentioned you’ll want different balustrade options later — when you’re ready, we can structure that as a dropdown that changes the description + price and keeps the cart line clear.)

Notes

• Supplied as an assembled staircase (as per your range setup).

• This is the Left-Hand version. A Right-Hand version is available separately.
