Staircase Highlights
• Staircase Type: Single-flight helical with sweeping cut-string treads
• Materials: Oak, curved glass and steel with waxed metallic effect
• Challenge: Achieving a uniform liquid finish across diverse materials
• Structural: Concealed steelworks and plating minimise deflection
• Aesthetic: A large, central wall creates a solid yet delicate structure
• Logistics: Delivered in three main parts using bespoke fabricated trolleys
The Outcome
A visually light helical staircase rises from the ground floor, resting on a single, point of contact as it meets ground level. The building’ s steel frame was specified to accommodate actual staircase loadings, making the client’ s chosen design a reality from the start. A bespoke metallic finish was applied to the staircase’ s central steel wall and perfectly matched to an elegant handrail using bonded polymers; lighting was integrated within the inner handrail to highlight its form and the patina of the feature wall.
