Why spiral staircase work in New Westminster
Custom steel and aluminum spiral staircases for interior and exterior applications, engineered to BC Building Code for residential and commercial use.
New Westminster spiral staircase work concentrates on heritage home secondary stairs in Queens Park, suite conversion basement stairs, and rooftop access spirals on Sapperton and Uptown townhouses. Queens Park heritage properties sometimes use period-appropriate iron or steel spirals for basement or attic access. Our Burnaby shop is 10 to 15 minutes from most New West sites.
New Westminster is the oldest city in BC and it shows in the building stock, Queens Park alone has hundreds of character homes from 1890 to 1920 with original railings, stair structures, and porch metalwork. Heritage restoration is a meaningful share of what we build here. At the same time, the Royal Columbian Hospital redevelopment in Sapperton (a $1.49B project) is driving institutional and commercial scopes, and density along Columbia Street continues to add multifamily work.

FAQs
Spiral Staircase questions from New Westminster clients
Answers to the questions we hear most often from New Westminster homeowners, architects, and GCs on spiral stairs projects.
Can you do period-appropriate spirals for Queens Park heritage homes?
Yes. Queens Park heritage homes occasionally need period-appropriate spirals for attic or basement access. We fabricate iron-look steel spirals with decorative detailing that match the early-20th-century architectural language.
How much does a custom spiral staircase cost in New Westminster?
Custom spiral staircase cost in New Westminster depends on diameter (residential 48", 60" versus commercial egress 60"+), tread material, guard type, whether the application is interior or exterior, and finish spec. Exterior galvanized spirals for deck and rooftop access have different cost drivers than architectural feature spirals with premium materials and guards. <a href="/request-a-quote/">Request a quote</a> with your site dimensions and application and we'll follow up with project-specific pricing.
Can a spiral staircase be used as primary egress in BC?
Only in limited cases. BC Building Code allows spiral stairs as primary egress for a single occupant area and secondary stairs serving a limited number of occupants. Most residential spiral installations are secondary stairs (loft access, rooftop access, basement secondary stair) because the tread geometry doesn't meet standard egress dimensions. We confirm code compliance for your specific application during the design phase.
What opening diameter and headroom does a spiral staircase need?
A 48-inch diameter spiral needs a 50 to 52 inch rough opening; a 60-inch diameter spiral needs 62 to 64 inches. Headroom requirement is 6'-4" minimum for code-compliant installations, with 6'-8" preferred. Floor-to-floor height determines tread count and rise per tread. We verify these dimensions during the initial site visit.
Do Sapperton new-build townhouses use rooftop access spirals?
Occasionally. Sapperton redevelopment townhouses with rooftop decks sometimes specify exterior spirals for access. These use hot-dip galvanized steel for climate durability.
Does the New West heritage overlay affect spiral stair projects?
For visible exterior spirals in Queens Park, yes, heritage review applies. Interior spirals are generally outside the heritage review scope unless they involve structural changes to heritage elements.
What is the New Westminster spiral project timeline?
6 to 10 weeks for standard projects. Heritage-area projects extend to 10 to 14 weeks because of overlay review.
