Custom Stair Systems
Custom one-off stair systems designed, engineered, and fabricated for the specific architectural, structural, and finish requirements of each project.
System Overview
Custom stair systems are developed around the needs of each project, from early design intent through fabrication and installation coordination. Each stair is built to respond to the space, structure, finish palette, and architectural goals of the home or building.
Our work includes floating stairs, mono-stringer stairs, dual-stringer stairs, channel-stringer stairs, remodel stairs, commercial stairs, and fully custom architectural stair systems.
Stair Types
• Floating stair systems
• Mono-stringer stair systems
• Dual-stringer stair systems
• Channel-stringer stair systems
• Remodel stair systems
• Commercial stair systems
• Fully custom architectural stair systems
Ideal Applications
Custom stair systems are ideal for projects where a standard stair solution will not meet the architectural intent, structural requirements, or finish expectations of the space. Each system is designed to feel integrated with the surrounding architecture rather than added on after the fact.
Available Options
• Wood tread species and finish
• Steel finish selection
• Glass, cable, bar, or picket railing systems
• Top-mount or side-mount railing coordination
• Open-riser or closed-riser configurations
• Project-specific dimensions and detailing
• Interior finish options including powder coat, black patina, or raw steel with oil sealer

Available Finishes
Powder Coat
Durable architectural finish available in a wide range of standard and custom colors.
Black Patina
A hand-applied finish that highlights the character of the steel while providing a refined appearance.
Raw Steel with Oil Sealer
Preserves the natural appearance of steel while providing protection for interior applications.
