Arke Staircases are used on a wide variety of projects and applications but British building regulations are complex and it is your responsibility to ensure that your chosen stair is compliant. As a broad rule of thumb the following is a guide only and must be verified by your local building inspector.

For General Storage Areas, mezzanines and areas requiring access for maintenance such as a loft or cellar, all models may be suitable.

• 120mm Dia: NON COMPLIANT.
• 140mm Dia: Complies with one exception, the minimum clear width is 566.5mm for the Klan and 585mm for the Civik. The recommendation is 600mm. Check with Building Inspector, most will allow.
• 160 & 150mm Dia: Complies.

• Kompact 74, 89 & 89BS: Complies.
• Karina (Space Saver): NON COMPLIANT unless there is no room for normal stair.

• ARKE Kompact 89BS is the only model to Comply.

• Riser Bar Kit must be fitted.
• Max Gap from wall (Kompact & Karina): Less than 50mm. If greater, an additional handrail (kit external railing) will be required.
• Max Rise: 220mm.
• Maximum of 16 rises allowed in any one flight. If a greater number of rises are required, a landing should be introduced at some point.
