A staircase of this description, if made four feet in width, might take up only one-third the usual space: it would be very applicable to offices and warehouses where room cannot be spared, and where staircases little better than ladders are used, but in such cases a baluster and hand-rail should be placed between each second step, to prevent persons falling.

The “Builder” of November, 1843, gave two views of an ingenious double spiral staircase then exhibiting at a manufactory in Berners Street, Commercial Road. It was described as extremely simple, the object being to provide for ascent and descent without chance of meeting or collision. It consisted of a deal or other board of suitable thickness 6 feet long and 12 inches wide, forming a double tread, and the riser crossed, as it were from corner to corner, except as arranged to form a newel in the centre, of about five inches in diameter. The staircase had twenty-two risers, and took one complete turn round.
