Wooden Staircases
Sculptural Vertical Engineering in Solid African Hardwoods
Transforming vertical circulation into the sculptural centerpiece of the home. We engineer and handcraft bespoke solid hardwood staircases—from cantilevered floating treads anchored to concealed steel spines to grand curving stairwells, closed-riser hardwood flights, and hand-turned baluster assemblies.
Wooden Staircases
Cantilevered, dog-leg, and solid hardwood staircases with hand-turned balustrades & bullnose treads.
Engineering, Geometry & Precision
How our master joiners and site engineers execute wooden staircases to European architectural tolerances.
Staircases are the architectural spine of multi-story residences. Our workshop fabricates each flight by pairing structural timber engineering with artisanal joinery. Whether designing a minimalist cantilevered floating staircase that appears weightless or a grand traditional closed-riser staircase with turned newel posts, every millimeter is cut, planed, and finished in our climate-controlled Nairobi workshop before on-site installation.
We exclusively mill seasoned African Mahogany (Khaya anthotheca), prime Mvule, and kiln-stabilized American White Oak, dried to 8–11% moisture content to prevent seasonal movement. Each tread features 38mm to 65mm solid wood thickness, routed anti-slip bullnose front edges, and structural mortise-and-tenon or concealed steel-bracket housings.
Our installation protocol eliminates creaks and structural vibration through polyurethane acoustic bedding and Torx T25 high-tensile structural fasteners. Treads are treated with three coats of non-yellowing, traffic-rated satin polyurethane to endure decades of continuous use.
From Laser Survey to 10-Year Handover
Our 5-phase delivery protocol ensures absolute clarity on timelines, structural quality controls, and client approvals at every milestone.
3D Laser Site Survey & Load Calculations
Laser measurement of finished floor heights, wall plumbness, and structural anchorage points. Generation of 3D CAD stair models with rise/run ergonomics.
- Architectural 3D CAD drawings
- Structural anchor schedule
- Rise & run calculation sheet
Hardwood Grain Selection & Kiln Stabilization
Hand-picking prime African Mahogany and Oak baulks with matching grain flow. Kiln stabilization and moisture meter verification.

On-Site Rigging, Structural Fastening & Leveling
Anchoring of concealed steel spine or timber carriage stringers, laser-leveling each tread, and securing with high-tensile fasteners and acoustic isolation pads.
- Anchor torque verification
- Deflection testing report
- Zero-creak acoustic check
Hand Finishing, Balustrade Fitting & Handover
Installation of handrails, newel posts, balusters, fine hand sanding to 320 grit, applying final satin polyurethane coats, and handing over with care guide.
- Finished staircase handover
- 10-Year Craftsmanship Certificate
- Hardwood maintenance kit
Hardware, Chemical & Structural Ratings
Fastening & Anchoring Protocol
Pre-drilled countersunk Torx T25 architectural timber screws with Wurth anchor studs into concrete/steel.
Kiln Moisture & Preservation
Kiln-dried hardwood calibrated to 8% – 11% moisture content with anti-borer boron salt immersion.
Load & Deflection Tolerance
Tested to 4.2 kN concentrated point load per tread with under 0.8mm dynamic deflection.
Finishing Chemistry & Sealants
3 coats of Bona Traffic HD non-yellowing satin polyurethane; scratch and alcohol resistant.
Sound Isolation Rating
Acoustic rubber isolation underlayment yielding sub-35dB footfall transmission.
Maintenance Lifecycle
25+ years structural lifespan; re-coating interval 7–10 years under residential traffic.
Precision Pre-Drill & High-Torque Screw Rig
We discard nails and soft slotted screws. Every structural joint in our fabrication is secured with calibrated brushless 18V drivers, carbide-tipped stepped pilot bits, and corrosion-resistant Torx architectural screws that eliminate squeaks, drift, and structural loosening.
