Chigwell, Essex
At this luxury residential house, we replaced an existing timber tread spiral with a new, more contemporary spiral stair that fitted better with the client’s aesthetic. You can’t get much more contemporary than a full glass spiral – steps included!
The stair is situated in the dining room that features a vaulted ceiling and upper mezzanine – the stairs lead up to the roof space snug. Previously they were made of powder-coated metal, with metal balusters and a dated style of timber tread, which matched the upstairs flooring but didn’t suit the very clean and modern style of the dining room.
The room the stair is situated in is very light and airy, with a double height glass façade, white walls and porcelain floor furnished with glass furniture – it had to have a glass staircase to match. The previous stair was dark and heavy in comparison so was quickly replaced with reflective stainless steel and toughened glass to bounce the light around.

Full glass spiral stair with stainless steel handrail and core pole
We designed, supplied and installed a glass and stainless steel “elite” spiral staircase including curved upper well edge balustrades to match the staircase flight. The treads and upper landing plate were made of triple laminated glass, frosted to allow light to filter but not be transparent. The inner column was mild steel for structural integrity but all visible metalwork was polished stainless steel, including the handrails, clamps, bosses and uprights. Our work also included the mezzanine glass balustrading to match the stair.
