EeStairs - Спиральная лестница

This helical domestic staircase at Lobith in the Netherlands, was designed by Art-line, and posed some interesting challenges.‎ The first was that EeStairs had to develop the detailed design of the stairs based on supplied sketches and measurements that were quite basic.‎ The inner edge of the stairs and the open, two-rail balustrade provide only relatively minor structural support.‎ Furthermore, the solid wood treads have no risers and are only linked with metal ‘pins’.‎ The solution was to set the outer edges of the treads into the stronger deep-shell structure of the outer balustrade.‎ In terms of fabrication and installation, this unusual structural arrangement was a big test for the geometric accuracy of the stairs—and particularly in the design, crafting, and installation of the two-rail balustrade, which curves through three levels in the house.‎ The visual impact is enhanced by an EePaint™ finish on the steel elements.‎ As you can see, the geometry of the rails remain true.‎ Further info from manufacturer on RESIDENCE LOBITH NL EeStairs
