Aesthetic Value: This double helical spiral stair is stained and visible on all sides. The lattice style platform at the top compliments the nautical style of the room, as well as the balcony with ocean view above. Stair Safety: This stair complies fully with spiral stair codes, and has an outside radius of 76”, much wider than a typical spiral, making it feel less confining and comfortable than a traditional spiral staircase. Quality of Workmanship: The stair is made entirely from African mahogany and is finished on all sides. Custom turned balusters were designed to meet the challenge of the tight quickly climbing radius of inside handrail and stringer. Technical Challenge: The stringers were transported fully assembled as one unit. The structure is supported only by the lattice landing at the top and free-standing concentric stringers. Inside volute was designed to nest inside the inner stringer.
