Spiral Stairs, Kelowna, BC
Custom steel spiral staircases for Kelowna, space-saving interior and exterior spirals, including rooftop and lakefront-deck access, fabricated at our Burnaby shop and installed across the Okanagan.
Spiral Stairs, Kelowna
Custom steel and aluminum spiral staircases for interior and exterior applications, engineered to BC Building Code for residential and commercial use.
Spiral staircases solve a footprint problem, and in Kelowna that comes up most often as exterior access to a rooftop deck or a lakefront lower level, a stair that reaches a view without consuming the floor plan. We fabricate spiral stairs in steel at our Burnaby shop and install in Kelowna as a planned trip down Highway 97. Exterior spirals up to a deck overlooking Okanagan Lake are a recurring request, and those get the full Okanagan exterior spec: UV-stable finish for the strong valley sun, galvanizing where the structure meets grade, and thermal-movement allowance. On wildfire-interface lots, a steel spiral is a non-combustible alternative to a wood exterior stair. Interior spirals to a loft or suite are powder-coated to match the home. Every spiral carries a sealed engineered drawing.
Kelowna is the largest city in the Okanagan and a high-value market for architectural metalwork, lakefront luxury homes, wine-country estates, and a fast-growing commercial and institutional core anchored by Kelowna General Hospital and UBC Okanagan. We fabricate in Burnaby and deliver finished assemblies to Kelowna via the Coquihalla and Highway 97, which fits the larger custom-residential and commercial scopes here. We delivered stair fabrication and installation for Interior Health at Kelowna General Hospital. Two local conditions shape the brief: the semi-arid Okanagan climate (hot summers, intense UV, lake exposure) and the wildfire-interface zones on the city's hillside margins, where non-combustible steel railings, gates, and structures are a genuine safety advantage over wood.
Configurations we fabricate
Kelowna context
Kelowna's climate, building stock, and permit process shape every spiral stairs project we deliver here.
Climate
Design snow load for Kelowna is roughly 1.9 kPa ground. Coastal exposure is none. Interior seismic zone, Okanagan valley; connections detailed per CSA W47.1. These are the numbers the engineer pulls when sizing steel for a spiral stairs here.
Permits
City of Kelowna requires building permits for structural work, new stairs, and guardrails. Properties in wildfire-interface development permit areas carry additional FireSmart-driven requirements, confirm with the Kelowna development services department.
Local neighbourhoods
We work throughout Kelowna, including Downtown, Lower Mission, Upper Mission, Pandosy, Glenmore, Dilworth, Rutland, Black Mountain. Most sites are a 4 hours via the Coquihalla and Highway 97 drive from our Burnaby shop.

Process
1. Site visit and opening check. Confirm the opening diameter, headroom clearance, and floor-to-floor height for code compliance.
2. Engineering. Sealed drawing sizing the central column, tread brackets, and guard system to code.
3. Shop drawings. Tread layout, column section, guard detail, and finish schedule.
4. Fabrication. Central column, tread brackets, and guard fabricated at our Burnaby shop.
5. Finishing. Powder coat for interior; hot-dip galv + powder coat for exterior applications.
6. Installation. 1 to 2 days for a residential spiral; longer for complex commercial applications.

FAQs
Answers to the questions we hear most often from Kelowna homeowners, architects, and GCs on spiral stairs projects.
Spiral stair cost in Kelowna depends on diameter, tread count, interior versus exterior, railing detail, and finish. Exterior weatherproof spirals cost more than a simple interior loft spiral. The Burnaby delivery is one planned install. <a href="/request-a-quote/">Request a quote</a> and we'll follow up with project-specific pricing.
Yes, it is one of the more common Kelowna spiral requests given the lake and valley views. Exterior spirals get hot-dip galvanizing where the structure meets grade, a UV-stable topcoat for the strong Okanagan sun, and thermal-movement detailing. The City of Kelowna permit and a sealed engineered drawing apply.
Yes. On the hillside-interface neighbourhoods, a steel exterior spiral is non-combustible, unlike a wood exterior stair. It is a practical choice on Upper Mission, Wilden, and Crawford Estates lots where reducing combustible exterior material matters.
The diameter is set by the BC Building Code tread-depth and headroom requirements and by whether the spiral is a primary or secondary route. We size it to the opening and confirm upper-landing headroom before fabrication, a welded steel spiral cannot be adjusted on site.
Yes. We fabricate the column, treads, and railing complete in Burnaby and install in one mobilization down Highway 97, the same model behind our Interior Health stair work at Kelowna General Hospital.
