New Trex Deck & Custom Spiral Staircase completed in Littleton, Colorado

Transforming an Older Deck into a Beautiful Outdoor Living Space
At Add A Deck of the Rockies, we recently completed another beautiful custom composite deck replacement in Littleton, Colorado. The homeowners wanted to replace their aging wood deck with a modern, low-maintenance outdoor living space that would improve both the appearance and functionality of their backyard.
One of the biggest challenges was providing easy access to the yard while preserving valuable outdoor space. Our solution was a custom 5’6″ diameter spiral staircase, allowing the homeowners to comfortably access their backyard without the larger footprint of a traditional staircase.
The result is a stunning outdoor living area that combines long-lasting materials, modern design, and exceptional craftsmanship.
Premium Trex® Composite Decking Built to Last
For this project, the homeowners selected Trex® Transcend® Lineage™ Hatteras composite decking and fascia. The warm, natural color complements the home’s architecture while providing the durability and low maintenance that Colorado homeowners appreciate.
Unlike traditional wood decks, Trex composite decking never requires sanding, staining, or painting and is engineered to resist fading, moisture, splintering, rot, and insect damage. It’s an ideal choice for Colorado’s intense sunshine, changing temperatures, snow, and hail.
Custom Spiral Staircase Saves Space
One of the standout features of this project is the custom 5’6″ diameter spiral staircase.
Rather than installing a conventional staircase that would consume a large portion of the backyard, the homeowners chose a custom spiral design with Trex Hatteras treads. The spiral staircase creates convenient access to the patio while preserving valuable outdoor living space for entertaining and landscaping.
Steel Framing for Superior Strength
To ensure decades of reliable performance, this deck was constructed using Newcastle steel framing and steel support posts.
Steel framing offers several advantages over traditional wood framing:
- Stronger structural support
- Greater resistance to moisture and rot
- Won’t warp, twist, or shrink
- Increased long-term durability
- Exceptional stability for composite decking
Modern Railing System
The finished deck features a combination of attractive railing systems designed for both safety and style:
- 70 linear feet of matte black iron railings
- 30 linear feet of vertical cable railing
The combination creates a clean, contemporary appearance while maintaining open sightlines to the backyard.
