Modern Staircases for Bordeaux & Southwest France — Wine Region Château, Atlantic Coast & Basque Villa
From 18e-century Bordeaux Chartrons townhouses and Saint-Émilion château renovations to Cap Ferret Atlantic surf coast villas, Biarritz Basque resort properties and Toulouse contemporary projects — bespoke modern staircases delivered as intra-EU supply across the Aquitaine and Occitanie regions.
Central spine staircase with oak treads — typical specification for Bordeaux Chartrons townhouse and Saint-Émilion château renovation projects across the Southwest.
Bordeaux and the broader Southwest of France present a distinctive project profile that doesn't fit the Paris or Riviera template. Three sub-markets define the region: Bordeaux urban (18e-century stone townhouses in Chartrons and Saint-Pierre, Haussmannian-era apartments around Pey-Berland and Place Gambetta, contemporary new-builds in Bassins à Flot and Bègles), wine region château (Saint-Émilion, Médoc, Sauternes — restored estate properties combining heritage envelopes with contemporary interventions), and Atlantic coast (Cap Ferret pinasse villas, Arcachon Belle Époque, Biarritz Basque resort, Hossegor surf coast — all requiring marine-grade specification but with milder Atlantic exposure than the Mediterranean Riviera).
This guide is the regional specification framework for Continox France projects across Aquitaine and Occitanie — including how the UNESCO-listed Bordeaux centre affects design freedom, the typical wine-region château renovation constraints, and the Atlantic coast marine specification (which differs meaningfully from Mediterranean Riviera spec). We supply floating cantilever, central spine and fully bespoke configurations alongside glass balustrades, balcony railings and external staircases. For underlying regulations see our CCH and NF standards guide, classification in the habitation privée vs ERP guide, glass specification in the glass balustrade regulations guide, and other regional contexts in our Paris, Côte d'Azur and Lyon guides.
Continox supplies bespoke modern staircases across Bordeaux and Southwest France from €7,999 supply-only for L-shape steel plates configurations (compact Bordeaux apartment), €8,999 for central spine (typical Chartrons townhouse and Saint-Émilion château renovation specification), and €11,500+ for premium central spine in Cap Ferret, Biarritz and top-end wine-estate projects. Atlantic coast projects within 1 km of the sea use marine-grade 316 stainless at no extra cost. Transit from our EN 1090-1 EXC2 facility near Kraków is 3–5 working days to Bordeaux via direct EU motorway.

The Southwest Context — Three Sub-Markets
Three things distinguish Bordeaux and Southwest France projects from the rest of the country:
UNESCO Heritage & Stone Building Stock
The historical centre of Bordeaux is a UNESCO World Heritage Site covering approximately 1,810 hectares — the largest urban heritage zone in France after Paris. The dominant building type is 18e-century stone-fronted townhouse with internal stone-and-timber stairwells, generous floor-to-floor (3.5–4.2 m), and original stone façades preserved under ABF and Plan de Sauvegarde regulation. Modern staircase insertions into these properties require sympathetic specification — the contemporary intervention should respect the heritage envelope without pastiche.
Wine Region Estate & Château Renovations
The Bordeaux wine region (Médoc, Saint-Émilion, Sauternes, Pessac-Léognan, Pomerol, Entre-deux-Mers) and surrounding Southwest wine areas (Cahors, Madiran, Jurançon) include hundreds of restored or partially restored château properties — many combining heritage estate buildings with contemporary additions. Continox's wine-region clients are typically Grand Cru estate owners specifying premium central spine or fully bespoke configurations as part of multi-million-euro renovation projects.
Atlantic Coast & Milder Marine Exposure
The Atlantic coast from Cap Ferret through Arcachon, Hossegor, Capbreton and Biarritz down to the Spanish border is fundamentally different from the Mediterranean Riviera. Atlantic exposure means higher rainfall and lower chloride aerosol concentration — sea spray is washed off by rain rather than baked on by sun. The Continox response: standard 316 marine-grade stainless rather than the 316L mirror-polished specification used on the Côte d'Azur. Heat-soaked glass remains standard for external installations.
Premium central spine with walnut treads and integrated LED — typical Saint-Émilion château and Cap Ferret pinasse villa specification.
Bordeaux UNESCO Centre & ABF Coordination
The UNESCO heritage zone covers most of central Bordeaux — Saint-Pierre, Chartrons, Saint-Michel, the Triangle d'Or commercial heart, and the riverfront quays. The regulatory framework adds two layers above the standard CCH for projects within this zone:
| Authority | Trigger | Staircase Implication |
|---|---|---|
| UNESCO heritage zone | All works within historical centre of Bordeaux | Façade-affecting works require ABF + Plan de Sauvegarde review; pure-internal staircases proceed normally |
| ABF (Architecte des Bâtiments de France) | Within 500 m of a monument historique | Review of works visible from public realm |
| Plan de Sauvegarde (PSMV) | Stricter sub-zones within UNESCO perimeter | Detailed material and specification rules for envelope works |
| PLU de Bordeaux | All works in Bordeaux Métropole | Floor-to-floor changes, structural modifications |
| Copropriété (assemblée générale) | Modifications to shared elements in apartment buildings | Structural study + AG approval required |
For the typical Bordeaux Chartrons or Saint-Pierre townhouse renovation, the staircase intervention is internal — replacing a degraded original wooden flight or inserting a contemporary insertion alongside a preserved heritage staircase. ABF review is rarely triggered for pure-internal works. The bigger constraint is structural: 18e-century stone-fronted buildings have load-bearing stone walls that need careful structural assessment before steel staircase anchoring. Continox supplies the structural load schedule (anchor pull-out, point loads, dynamic deflection) at quotation stage.
Wine Region Château Renovations
The Bordeaux wine region and surrounding Southwest wine areas form the most architecturally ambitious sub-market in the region. Estate renovation projects typically combine preserved heritage chai (wine cellar) and reception buildings with contemporary owner residences and tasting facilities. The modern staircase serves the latter — usually within a contemporary extension or a fully renovated wing of the original château.
Wine Region Estate — Typical Specification
- System: Premium central spine, Y-shape, or fully bespoke geometry — architectural sculpture-piece for owner's residence or tasting room
- Width: 110–130 cm typical (generous footprint, no apartment-stairwell constraint)
- Tread material: Walnut or oak with optional bronze-toned hardware accents — sympathetic to wine-region material palette
- Glass: Frameless full-height balustrade, sometimes both sides, opening sightlines through the renovated space
- Lighting: Integrated LED tread lighting standard; some projects specify ambient gold-cast lighting matching reception tasting lighting
- Heritage interface: CAD coordination with conservation architect for connections to original stone or timber structure
- Documentation: Full Eurocode structural pack with French national annex; coordination with maître d'œuvre and architect du patrimoine
- Budget context: Staircase typically €15,000–€30,000+ for top-end estate projects with multi-million-euro overall renovation
Y-shape central spine — the architectural sculpture-piece configuration for wine-region château renovation projects in Saint-Émilion, Médoc and Pessac-Léognan.
Atlantic Coast — Cap Ferret to Biarritz
The Atlantic coast of Southwest France stretches from the Bassin d'Arcachon (Cap Ferret) down through Hossegor, Capbreton, and the Côte Basque (Biarritz, Bidart, Saint-Jean-de-Luz). Three things distinguish Atlantic specification from Mediterranean Riviera:
| Factor | Mediterranean Riviera | Atlantic Southwest Coast |
|---|---|---|
| Marine exposure intensity | High — calm sea, baked-on chloride aerosols | Moderate — Atlantic rain washes off chloride |
| Standard stainless spec | 316L mirror-polished (waterfront) | 316 standard (within 1 km coast) |
| Steel structure finish | Hot-dip galvanised + duplex | Galvanised + RAL powder-coat (sufficient) |
| Glass spec | Heat-soaked tempered laminated | Heat-soaked tempered laminated (same) |
| Wind loading | Moderate (Eurocode zone 2) | Higher (Eurocode zone 3 — Atlantic exposure) |
| UV exposure | Very high — Mediterranean sun | High but moderated by Atlantic cloud cover |
The Atlantic coast (Eurocode wind zone 3) generates higher horizontal wind loads on external balustrades and terrace garde-corps than the Mediterranean Riviera. For external installations, Continox sizes glass thickness and fixing density to the specific zone — VSG 21.52 (10+10 mm) heat-soaked at 1.6 m maximum span on Atlantic coast vs 2.0 m on Riviera. Internal staircase balustrades use the same VSG 17.52 specification regardless.
Point-fixed glass balustrade with 316 marine-grade stainless fittings — typical Cap Ferret pinasse villa and Biarritz Basque coast specification.
Neighbourhoods We Supply Most Often
Bordeaux Centre — Chartrons & Saint-Pierre
The most dense townhouse market in Southwest France. Chartrons (former wine merchant district) and Saint-Pierre (medieval core) within UNESCO perimeter. Most projects involve sympathetic contemporary insertions into 18e-century stone townhouses with original timber stairwells.
Typical: Central spine 90–110 cm, oak treads, frameless glass — sympathetic to heritage envelope
Bordeaux — Pey-Berland & Triangle d'Or
Bordeaux's Haussmannian-era apartment district around Place Pey-Berland and the Triangle d'Or commercial heart. Mixed residential and commercial. Strong demand for premium central spine duplex insertions in apartment renovations on Cours de l'Intendance and Allées de Tourny.
Typical: Central spine 90–100 cm, oak or walnut, premium specification
Pessac & Bordeaux Métropole West
Bordeaux's prestigious western suburbs — Pessac, Talence, Caudéran, Mérignac. Mix of interwar villa stock and contemporary new-build. Pessac-Léognan wine appellation overlaps the western edge with several château residences requiring premium specification.

Frequently Asked Questions
How long does Continox delivery to Bordeaux take?
Transit from our EN 1090-1 EXC2 facility near Kraków to Bordeaux is 3–5 working days by dedicated freight via direct EU motorway. The full programme from order confirmation to site delivery is 4–8 weeks (1 week 3D, 3–6 weeks fabrication, 3–5 days transit). For wine-region château and Cap Ferret villa projects with bespoke geometry, fabrication adds 2 weeks.
Do you supply Bordeaux UNESCO heritage projects?
Yes. The vast majority of Bordeaux UNESCO-zone projects are internal townhouse or apartment renovations that don't trigger ABF or Plan de Sauvegarde review. Continox supplies the structural load schedule and 3D visualisations early so the architect can coordinate with heritage authorities and copropriété syndic in parallel. For projects affecting building envelope, we coordinate with conservation architects throughout the design phase.
What's the most-specified system for Saint-Émilion château renovations?
Premium Central Spine (from €11,500), Y-Shape Central Spine (from €10,999) and Fully Bespoke (from €12,999) dominate the Saint-Émilion and Médoc wine-region market. Walnut treads with bronze-toned hardware accents are typical, integrated LED tread lighting standard. Top-end château specification reaches €20,000–€30,000+ as part of multi-million-euro renovation projects.
Is Atlantic coast marine specification different from Mediterranean?
Yes. The Atlantic Southwest coast (Cap Ferret, Arcachon, Biarritz) uses standard 316 marine-grade stainless rather than the 316L mirror-polished specification used on the Mediterranean Riviera. Atlantic rainfall washes off chloride aerosols rather than baking them on, reducing corrosion intensity. Heat-soaked glass remains standard for external balustrades. Higher Atlantic wind loading (Eurocode zone 3) is sized into the structural calculations.
How much does a Cap Ferret villa staircase cost?
Cap Ferret pinasse villa specification typically ranges €13,000–€18,500 supply-only ex-works EU, plus €1,200–€1,500 delivery to the Bassin d'Arcachon. Premium central spine 110–120 cm wide with walnut treads, Atlantic marine spec (316 stainless, heat-soaked glass), integrated LED tread lighting. Fully bespoke geometry for top-end Cap Ferret villa projects can reach €22,000+.
Do Toulouse projects need marine specification?
No — Toulouse and surrounding Occitanie inland (Albi, Castres, Montauban, Cahors) are well inland, no marine spec required. Standard 304 stainless and tempered laminated glass applies. Marine upgrade applies only to Atlantic coast projects within 1 km of the sea. For Toulouse "Ville Rose" projects specifically, the brick-faced building stock supports any standard Continox configuration.
Can a modern staircase fit a Bordeaux 18e-century townhouse?
Yes — Chartrons and Saint-Pierre 18e-century townhouses typically have generous floor-to-floor heights (3.5–4.2 m) with original timber stairwells. Continox specification: central spine or U-shape central spine, 100–110 cm wide, oak treads sympathetic to heritage envelope, frameless glass to preserve sightlines through the original stone shell. Structural anchoring requires careful coordination with the load-bearing stone walls.
How much does a Bordeaux Chartrons renovation staircase cost?
Bordeaux Chartrons townhouse renovation specifications typically range €8,999–€13,000 supply-only ex-works EU. Central spine 100 cm wide with oak treads matching restored timber elements, frameless glass balustrade, sympathetic to heritage envelope. Delivery adds €900–€1,200 within Aquitaine. The structural assessment to coordinate with original stone walls is included in the design phase.
What about Biarritz and Basque coast projects?
Biarritz Belle Époque palaces and Basque coast villas (Bidart, Saint-Jean-de-Luz, Anglet) use Continox Atlantic marine specification — 316 stainless throughout, heat-soaked glass, RAL powder-coat steel structure. Premium central spine 110–120 cm with walnut treads is the most-specified configuration. Pricing typically €13,000–€18,500 supply-only, €1,300–€1,600 delivery.
Do you supply matching glass balustrade for Atlantic coast terraces?
Yes — combined supply (staircase + glass balustrade + balcony railings + external garden steps) is the standard delivery model. For Cap Ferret, Biarritz and Atlantic terrace installations, glass specification follows the same NF EN 12150 + NF EN 14449 + NF EN 12600 1B1 framework with heat-soaked tempered laminated glass and 316 marine-grade fixings. Combining typically reduces overall project cost by 8–12% vs separate orders.
