Quarter-turn double staircase in beech or oak – stable and adjustable structure

This quarter-turn double staircase in glued laminated beech or oak is designed for interior fittings requiring a comfortable ascent and optimised footprint. Its two-turn geometry allows the staircase to be integrated into constrained stairwell configurations, while maintaining a regular progression thanks to a tread depth of 21 cm and a riser height of 19 cm. Workshop machining guarantees a stable interlocking between the stringers, steps and newel posts. The floor-to-floor height of 285 cm is adjustable on site to adapt precisely to the finished floor level. The staircase is delivered without an interior handrail: if a handrail is required, it must be purchased separately and installed at the same time to ensure correct alignment. This model meets searches related to quarter-turn double staircases, the choice between beech and oak, and interior space-saving solutions.

Maintenance and protection

For interior use, it is recommended to apply a finish suitable for beech or oak: oil, varnish or wood stain, depending on the desired appearance. Regular maintenance (dusting, gentle cleaning) helps limit soiling and stabilise the colour of the wood. Avoid prolonged sources of moisture and periodically check the tightening of fixings (steps, stringers, newel posts, handrail where applicable).

FAQ – Quarter-turn double staircase in beech or oak

1. How to install a quarter-turn double staircase in beech or oak?

Installation consists of positioning the stringers and newel posts, placing the steps in the planned order and then adjusting the floor-to-floor height if necessary. The interior handrail, if planned, must be fitted at the same time as the staircase.

2. What is the lifespan of this quarter-turn double staircase?

For interior use with a suitable finish and regular maintenance, a glued laminated beech or oak staircase offers a service life of several decades, provided installation conditions are respected and excessive moisture is avoided.

3. Is this staircase compatible with an interior handrail?

Yes. The interior handrail is optional and not included. It must be purchased separately and installed at the same time in order to guarantee correct alignment and fixing.

4. What is the best quarter-turn double staircase to optimise a small space?

A quarter-turn double staircase with a controlled footprint, a tread depth of 21 cm and a riser height of 19 cm allows a comfortable ascent while fitting into constrained stairwell openings.

5. Why choose this quarter-turn double staircase rather than a straight staircase?

Compared to a straight staircase, the quarter-turn double shape distributes the ascent over two turns, allows obstacles to be bypassed and reduces the floor footprint, while maintaining a regular progression.
