Sculptural steel stairs as centrepiece
2015, Hamburg
An extravagant floor plan with half- and quarter-turned flights and elegantly curved radii emphasises the slender architecture of the sculptural interior stairs in this historic villa.
Steel stairs | Sculptural design
These steel stairs are the unique centrepiece of a historic city villa in Hamburg and reflect the excellent properties of steel. An extravagant floor plan with half- and quarter-turned flights is complemented by elegantly curved radii, giving the interior stairs a fascinating imposing appearance despite their extremely slender shapes.
Parapet-high flat-steel stringers run along both sides as railings. The smooth flat-steel cladding on the underside emphasises the sculptural and striking design of the steel stairs. A steel profile angle, top-attached onto the steel stringers and provided with indirect LED lighting, serves as a handrail. The historic building was given a masterfully realised, customised architectural element with this steel stairs.
