Modern Staircases for Geneva, Lausanne & Lac Léman — Bespoke Specification for Switzerland's French-Speaking Premium Market
From Geneva Vieille-Ville renovations and Cologny lakeside villas to Lausanne Belle Époque apartments, Vevey-Montreux Riviera residences, Nyon Côte townhouses and the Vaud premium villa stock — bespoke modern staircases engineered to SIA 358 with French-language project coordination.
Floating cantilever with aged oak treads — typical Cologny, Vandoeuvres or Lake Léman lakeside villa specification with reinforced concrete frame substrate, double-height living and lake-orientation aspect.
The Geneva, Lausanne and Lac Léman regional market is the architectural heartland of Romandie French-speaking premium residential. Three things define it: a strong international and diplomatic client base driving cross-cultural specification standards, the protected heritage envelope typical of Geneva Vieille-Ville and the Lausanne Belle Époque apartment stock, and the Lac Léman lakeside corridor from Nyon through Vevey, Montreux and Villeneuve which drives the highest-value villa specifications in the Cantons of Genève and Vaud. Combined market — Cantons Genève, Vaud, plus the Valais French-speaking lakeside fringe — represents the second-highest concentration of premium residential staircase projects in Switzerland after Zürich/Goldküste.
This guide covers the regional specification framework for Continox Switzerland projects across Romandie — typical altitudes (mostly mid-altitude lakeside, no S355J0 cold-resistant grade unless property exceeds 800 m or sits above the Vaud Riviera back-country), the urban-vs-lakeside split, French-language coordination, and the configurations most suited to each context. We supply floating cantilever, central spine and fully bespoke configurations alongside glass balustrades, balcony railings and external staircases. For underlying regulations see our SIA standards guide, classification details in the private vs commercial guide, and glass specification in the glass balustrade regulations guide. Other regional contexts in our Zürich, Zug & Goldküste guide.
Continox supplies bespoke modern staircases across Geneva, Lausanne and Lac Léman from €8,999 / CHF 9,500 supply-only for entry-level central spine specification (apartment renovation, 90 cm width, oak treads), and €11,500–€18,500 / CHF 12,300–CHF 19,800 for premium Cologny / Lac Léman villa (premium central spine 120 cm, walnut + bronze + integrated LED), reaching €18,000–€30,000+ / CHF 19,300–CHF 32,200+ for Geneva diplomatic-quarter or Cologny ultra-luxury bespoke. All projects use standard EN 1090-1 EXC2 manufacturing with S275 structural steel; S355J0 cold-resistant grade applies only above 800 m altitude (rare in Romandie — Saint-Cergue, Leysin, Villars-sur-Ollon). Transit from Kraków: 4–6 working days via France–Geneva or Germany–Basel corridor with Swiss customs clearance handled.
The Regional Context — Romandie Premium
Three things distinguish the Geneva, Lausanne and Lac Léman market from elsewhere in Switzerland:
Strong International & Diplomatic Client Base
Geneva is home to the United Nations Office at Geneva (UNOG), the World Health Organization, the World Trade Organization, the International Labour Organization and over 30 other major international organisations — driving a significant international and diplomatic-grade residential market. The international quarter (Petit-Saconnex, Pregny-Chambésy area) has its own architectural language; nearby Cologny and Vandoeuvres host much of the diplomatic-private and corporate-executive villa stock. Specification expectations calibrate to international rather than purely Swiss standards — communications often need to span English/French/sometimes Italian or German.
Geneva Vieille-Ville & Lausanne Belle Époque — Heritage Renovation Density
The historic centres of Geneva (Vieille-Ville, Cathédrale Saint-Pierre area) and Lausanne (Cité, Riponne, Saint-François) are dominated by protected heritage townhouse and apartment stock. Stairwells are typically constrained, heritage envelopes restrict major structural modifications, and central spine configurations dominate over floating cantilever. Cantonal Bauordnung (Geneva LCI - Loi sur les constructions et les installations diverses; Vaud LATC) adds sympathetic-insertion requirements for protected façades and heritage-listed envelopes.
Lac Léman Riviera — Premium Lakeside Continuum
The Lac Léman shoreline runs roughly Nyon through Coppet, Versoix, Genthod, Cologny (south shore Geneva), then arcs through Vaud — Morges, Lausanne, Vevey, Montreux, Villeneuve. The corridor delivers Switzerland's second-highest concentration of premium lakeside villa after the Zürichsee Goldküste. Property prices regularly exceed CHF 20,000 per square metre; villa staircase budgets routinely sit in the CHF 15,000–CHF 30,000 range. Reinforced concrete frame substrates support floating cantilever and Y-shape configurations comfortably.
Premium central spine staircase with walnut treads — typical Lausanne Belle Époque apartment renovation and Vaud Riviera villa specification with frameless glass balustrade and integrated LED tread lighting.
Urban Heritage vs Lakeside Villa New-Build
The single most important distinction within the regional market is between protected urban heritage (Geneva Vieille-Ville, Champel, Lausanne Belle Époque, Vevey old town) and lakeside villa new-build or generous-renovation (Cologny, Vandoeuvres, Genthod, Lutry, Vevey-Montreux Riviera). Each context drives a fundamentally different specification approach.
| Project Type | Typical Width | Substrate | Recommended System | Aesthetic |
|---|---|---|---|---|
| Geneva Vieille-Ville renovation | 80–100 cm | Original masonry — limited moment capacity | L-Shape Steel Plates or Central Spine | Sympathetic, restrained, dark-finished steel |
| Champel premium townhouse | 100–120 cm | Mixed — early-20e and reinforced | Central Spine or Premium Spine | Belle Époque-respectful, walnut + bronze accents |
| Cologny / Vandoeuvres villa | 120–150 cm | RC frame standard | Floating, Y-Shape, Bespoke | Architectural drama, lake-view orientation |
| Lausanne Belle Époque apartment | 90–110 cm | Original masonry / mixed | Central Spine or U-Shape Spine | Belle Époque insertion, oak + bronze restraint |
| Vaud Riviera villa (Vevey-Montreux) | 110–140 cm | RC frame typical | Floating, Premium Spine, Y-Shape | Lake-view orientation, generous floor-to-floor |
| Nyon Côte / La Côte | 110–130 cm | Mixed — RC and reinforced | Premium Central Spine, Floating | Vineyard-villa contemporary, tasteful restraint |
| Genthod / Versoix lakeside | 120–140 cm | RC frame | Floating, Y-Shape, Premium Spine | Diplomatic-grade, walnut + integrated LED |
| Lavaux UNESCO terraced vineyard area | 100–120 cm | Heritage stone + RC reinforcement | Central Spine, Premium Spine | Heritage-respectful, vineyard-context restraint |
For Geneva Vieille-Ville, Lausanne Cité and Vevey old-town renovation projects, the existing masonry substrate often cannot carry floating cantilever moment loads without significant wall reinforcement (CHF 8,000–CHF 18,000 typical). For these projects Continox typically recommends central spine configurations — self-supporting via the spine itself, with end-anchorages only at top and bottom landings. Reads as deliberate sympathetic insertion vs visual weightlessness; better fit for protected heritage envelopes. We discuss the substrate reality at quotation stage.

Most Geneva, Lausanne and Lac Léman lakeside projects sit at lake elevation 372–470 m — well below the 800 m threshold that triggers cold-climate specification. Standard S275 structural steel grade is used; thermal expansion clearances are standard 4 mm; powder-coat is standard polyurethane. The S355J0 cold-resistant grade applies only to the rare back-country project above 800 m altitude — Saint-Cergue (1,041 m), Leysin (1,250 m), Villars-sur-Ollon (1,250 m), Les Diablerets (1,150 m). For typical Cologny / Lavaux / Lausanne projects, expect standard specification at standard pricing.

How does Continox handle Geneva Vieille-Ville heritage renovations?
For Vieille-Ville and Lausanne Cité renovation projects within protected heritage zones, we work with the project's Swiss-registered architect who handles the cantonal Office des autorisations de construire (Geneva LCI) or Service des constructions (Vaud LATC) sympathetic-insertion review. Continox supplies central spine configurations (most heritage-compatible — sympathetic, structurally non-invasive), with options for matt black powder-coat to recede visually. Renovation timing typically allows 6–8 week fabrication lead time; cantonal autorisation dossier preparation takes additional 4–8 weeks for protected envelopes.
What's different about Cologny / Vandoeuvres villa specification?
Three typical Cologny / Vandoeuvres characteristics: generous width (120–150 cm minimum), walnut treads with optional bronze hardware accents, integrated LED tread lighting standard. Reinforced concrete frame substrates support floating cantilever and Y-shape configurations comfortably. Lake Geneva orientation drives double-height living arrangements where the staircase functions as a centrepiece visible from the entrance hall and main living spaces. Diplomatic and corporate-executive client base sets premium specification expectations.
How long does delivery to Geneva and Lausanne take?
Transit time from our EN 1090-1 EXC2 facility near Kraków: 4–5 working days via either France–Geneva (A4–A36–A40) or Germany–Basel (A4–Basel–A1) motorway corridor, plus 4–8 hours Swiss customs clearance. Full programme order to delivery: 5–8 weeks (1 week 3D, 3–6 weeks fabrication, 4–6 days transit + customs). Bespoke geometry adds 2–3 weeks fabrication; Cologny villa premium with integrated LED adds 1–2 weeks.
Do I need cold-climate specification for Vaud back-country projects?
Most Lac Léman and Vaud Riviera projects sit at lake elevation (372–470 m) and use standard S275 structural steel grade. Cold-climate S355J0 grade applies only to back-country properties above 800 m altitude — Saint-Cergue (1,041 m), Leysin (1,250 m), Villars-sur-Ollon (1,250 m), Les Diablerets (1,150 m), Château-d'Œx (970 m). For these specific high-altitude properties Continox specifies S355J0 + 6–8 mm thermal expansion clearances + heat-soaked glass standard — included automatically at no extra cost.
Can I get pricing in CHF rather than EUR?
Yes — Continox publishes both EUR and CHF prices for the Swiss market. CHF pricing is locked at quotation for 30 days regardless of currency movements, protecting from FX risk during the 4–8 week project programme. Final invoice in CHF or EUR at your election. Payment terms standard 30/60/10 (30% on order, 60% on dispatch, 10% on installation completion).
How does Continox coordinate with my Romandie architect?
Communications and documentation in English plus French as standard for Romandie projects. Free 3D visualisation within 5 working days of order — your architect signs off the design before manufacturing. CAD files supplied in formats compatible with all major Swiss canton submission systems including Geneva eCC and Vaud Camac platforms. Continox project manager fluent in English + French handles the entire project lifecycle. Site visits available for €20,000+ projects on request.
What about Swiss earthquake (séisme) verification in Romandie?
Cantons Genève and Vaud fall within seismic zones Z1a–Z1b (lower seismic zones in Switzerland) per SIA 261 — comparable to Zürich/Zug. Valais French-speaking Riviera fringe enters Z2 for some valley locations. For typical residential projects in Z1, Eurocode 8 / SIA 261 seismic verification of anchor connections is straightforward and Continox supplies it as part of the standard structural calculation pack. For Z2 properties (Bex, Aigle, Saint-Maurice valley), additional anchor specification is calculated automatically.
Does Continox handle Swiss customs and TVA?
Yes — our nominated Swiss freight partner handles T1 transit document, Swiss customs clearance and TVA processing at the Basel or Geneva (St-Julien-en-Genevois) border crossings — typically 4–8 hours. Continox supplies all required pre-shipment documentation (commercial invoice, packing list, TVA schedule, EUR1 origin certificate). The bilateral EU-CH free trade agreement means no import tariffs apply on EU-manufactured goods. For B2B projects, TVA 8.1% can be either included (DDP) or handled by your Swiss customs broker (DAP) — your choice.
Can you supply staircase + matching glass balustrade as one project?
Yes — combined supply (staircase + glass balustrade + matching balcony railings for adjacent terrace and mezzanine areas) is the standard Continox Switzerland delivery model. Glass specification per SIA 358 + EN 14449 + EN 12150 + EN 12600 1B1 — see our glass balustrade regulations guide. Combining typically reduces overall project cost by 8–12% vs separate orders, with single bilingual SIA + EN documentation pack and single Swiss customs clearance.
Who installs the staircase in Geneva or Vaud?
Installation is by your project's appointed Swiss metalwork contractor or main contractor's installation team. Continox supplies pre-engineered components with full bilingual assembly drawings and remote technical support during installation (video calls, CAD clarifications). For Cantons Genève and Vaud we have working relationships with recommended installers — referrals available on request. We do not subcontract installation directly; this is the local contractor's responsibility under their own SIA 118 contract framework and Swiss insurance.
