Longchamp Feature Staircase

The UK flagship store of Longchamp is an elegant and impressive 3,229 sq ft store on London’s Regent Street.
It opened in September 2013 after the interior had been completely remodelled by the luxury brand’s in house team.

For the interior Littlehampton Welding were asked to supply and fit two feature stairs and balustrades, one rising from the ground floor to the mezzanine level, and a further stair from the mezzanine level to the first floor.

The stair rising from the ground floor is curved, with a wide ‘mouth’ tapering as it rises in two flights with an intermediate landing between to the mezzanine level, and is fabricated from mild steel with 6mm thick folded mild steel tread pans. The fabricated structure is then bolted with M10 grade 8.8 bolts to angle cleats welded to the stair stringers.

The balustrade is formed from 21.5mm thick heat soaked and toughened low iron laminated glass with drilled holes for a countersunk screw connection into a captive nut on the inside the end-plates of the folded tread plates. A timber handrail is secured to a 20mm square stainless steel core rail with wood screws and the core rail is welded to 12mm square handrail pins which in turn are welded to a pair of 40mm square stainless steel rubber faced glass clamp plates.

The stair from the mezzanine floor to the first follows the same design as described above but rising in one continuous flight, and with no supports to the underside of the stair.

All stainless steel parts are satin polished, and the mild steel parts are shot blasted and primed with a high build zinc phosphate primer and finish painted with a 2 pack 30% gloss acrylic paint.
