When it comes to optimizing space and adding architectural interest, spiral staircases are a stylish and functional solution for both interior and exterior settings. At Colorado Deck Works, we specialize in designing and installing custom spiral stairs that complement your home or deck while meeting Colorado’s unique climate and code requirements. Whether you’re looking to connect multiple levels outdoors or enhance the look of an interior space, spiral staircases provide a compact and visually appealing alternative to traditional stairs.
A spiral staircase is a compact stair system that coils upward around a central support column. Each tread is wedge-shaped, allowing the staircase to form a circular or helical shape. This design allows the staircase to occupy a much smaller footprint than traditional staircases. Whether installed indoors to connect lofts or basements, or outdoors to link a deck to the ground level, spiral stairs offer space-saving convenience with a touch of visual flair.
Spiral vs. Traditional Staircases
Footprint and Layout
Traditional staircases often require long runs and broad landings, taking up considerable floor space. Spiral staircases, by contrast, are extremely compact. Their minimal footprint makes them perfect for small areas where space is limited or where a sleek design is desired.
Usability and Safety
Spiral staircases can be steeper and narrower than standard staircases. While they work beautifully for secondary access points or accent features, they may not be ideal for those with mobility issues or when moving large items between levels.
“Spiral staircases often save space as they only need a small footprint for installation. Unlike traditional models, spiral stairs only take up floor space equal to their overall width. However, because they take up less square footage, they are steeper than traditional stairs, which can be problematic for small children, pets, and people with mobility issues.”
While prefabricated spiral stair kits can be relatively affordable, custom-built spiral stairs may come with a higher price tag due to the precision and craftsmanship involved. However, the space-saving nature often reduces site preparation costs, especially for multi-level decks.
Aesthetic Appeal
Spiral staircases bring dramatic visual interest to any space. Their curved lines and vertical elegance make them ideal focal points, and customization options allow for a range of styles – from rustic mountain charm to modern minimalism.

Materials Used for Spiral Staircases and Railings
Structural Core
For outdoor staircases, steel is a popular choice due to its strength and durability. Powder-coated or galvanized steel resists rust and withstands Colorado’s variable weather. Aluminum is another corrosion-resistant option, especially in lighter-duty applications. For interior spiral stairs, wood offers a warm and classic appearance, often used in combination with a steel core for added support.
Treads
Metal treads with anti-slip textures are ideal for exterior stairs, providing safety and longevity. For indoor applications or custom decks, wood or composite tread overlays can add warmth and texture while maintaining structural performance.
Railings and Balusters
Common railing materials include powder-coated steel, stainless steel cables, and wood. Vertical balusters provide traditional styling, while horizontal or cable railings lend a modern look. Wood handrails are frequently used for interior stairs or in transitional design styles that mix natural and industrial elements.
Why Spiral Staircases Make Sense for Decks and Indoor Spaces
Climate Expertise
Colorado Deck Works understands the unique challenges of mountain environments, from freeze-thaw cycles to elevation-driven building codes. Our team ensures each staircase is engineered and installed with these conditions in mind.
Design Flexibility
At Colorado Deck Works, we customize every spiral stair project to complement your home’s architecture. Choose from a variety of tread materials, railing styles, finishes, and stair diameters to match your vision – whether it’s rustic, contemporary, or transitional.
Added Home Value
Spiral staircases enhance both function and style, offering a unique architectural feature that appeals to future homebuyers. A thoughtfully designed spiral stair adds curb appeal, improves outdoor access, and elevates interior aesthetics.
Space Efficiency
Spiral staircases are a go-to solution for decks with limited square footage. Because they rise vertically, they require less horizontal space than a standard staircase, leaving more room for furniture, landscaping, or walkways.
Visual Impact
Whether installed inside or out, spiral stairs serve as design centerpieces. Their flowing curves and vertical rise create striking visual interest. Add lighting beneath the treads or integrate modern railings for an even greater effect.
