Stylish Spiral Staircase for Lofts, Mezzanines & Small Spaces
The DOLLE CALGARY Spiral Staircase is the perfect solution for creating safe and stylish access to lofts, mezzanine floors, raised living areas, and compact interior spaces. Designed to maximise floor space while adding a modern architectural feature to your home, the CALGARY staircase combines Scandinavian design with exceptional practicality.
Finished in contemporary Anthracite (RAL 7016) with high-quality multiplex treads and landing platform, this modern spiral staircase delivers outstanding durability and timeless style.
Space Saving Spiral Staircase Design
The CALGARY spiral staircase is available in two diameter sizes:
- 120 cm diameter
- 140 cm diameter
Its compact footprint makes it ideal for:
- Loft conversions
- Mezzanine floors
- Small homes
- Studio apartments
- Home offices
- Secondary stair access
The substantial landing platform can be installed directly onto the ceiling opening and can also be adapted for round ceiling openings, offering excellent installation flexibility.
Adjustable Floor-to-Floor Height
The DOLLE CALGARY staircase is designed to adapt easily to different ceiling heights.
Key Measurements:
- Maximum floor-to-floor height: 280 cm
- Minimum floor-to-floor height: 204 cm
- Adjustable pitch height from 20.4 cm to 23.4 cm
The staircase height can be adjusted using the supplied spacer rings or by removing treads to achieve the perfect fit for your space.
Recommended Ceiling Openings:
- 130 cm opening for 120 cm staircase
- 150 cm opening for 140 cm staircase
For the most comfortable climbing experience, fewer spacer rings are recommended as this reduces the gap between treads.
Enhanced Safety Features
The CALGARY Spiral Staircase can be upgraded with additional safety components to help meet UK building regulation requirements for main staircases.
Optional safety upgrades include:
- Middle banister packs to reduce spindle gaps
- Riser bar kits to close gaps between treads
- Improved climbing comfort and stair safety
- Reduced openings to below 100 mm when fitted correctly
These additional features make the staircase safer for family homes and everyday use.
