ALBULA double quarter turn staircase

ALBULA Double Quarter-Turn Staircase – Comfort Range, 288 cm, 18 cm Riser Height, 22 cm Tread Depth

The ALBULA is a double quarter-turn staircase from the Comfort range, available in laminated beech, oak or fir. Its double quarter-turn layout changes direction twice by 90°, allowing installation in a rectangular 164x175 cm stairwell opening. The floor-to-floor height is 288 cm with 15 treads, an 18 cm riser height and a 22 cm tread depth – optimal proportions according to the Blondel formula.

The width is 80 cm. Available with or without risers and a handrail. Specify right- or left-hand orientation when ordering. The rectangular 164x175 cm stairwell opening (not square) is easier to accommodate than the 180x180 cm double quarter-turn models: it can fit where a square opening would not be possible. The ALBULA is the Comfort version of the ALBULA Standard (same footprint, 22 cm tread depth versus 19 cm for the Standard).

Installation advice

Check the stairwell opening (164x175 cm minimum) using finished dimensions – it must be rectangular, not square. Determine the orientation of the double quarter-turn before ordering; it cannot be changed. Pre-drill beech and oak. At least two people are needed to assemble a double quarter-turn staircase. If a handrail is included, install it during assembly, not after the staircase is fully assembled. Apply the finish after installation is complete.

Care and protection

Apply 2–3 coats of floor varnish (beech, oak) or an oil-wax finish (fir) before first use. For a heavily used main double quarter-turn staircase, floor varnish is recommended for all wood species. Reapply every 5–7 years. For routine cleaning, use a damp cloth and a pH-neutral cleaner.

WoodUp advice

The ALBULA differs from other WoodUp double quarter-turn staircases in its rectangular 164x175 cm stairwell opening: it is narrower in one direction (164 cm) and longer in the other (175 cm). This asymmetry allows installation where a square 180x180 cm opening is not possible. Check the orientation of the opening carefully before ordering (164 cm along the short axis and 175 cm along the long axis): a reversed 175x164 cm opening may cause orientation problems.

Good to know before buying: the ALBULA Comfort range offers the same climbing comfort as the straight GAVIA (18 cm riser height / 22 cm tread depth) in a double quarter-turn configuration. If your space allows, it offers the best balance of comfort and flexible positioning.
