Our bespoke mono stringer staircase with frameless glass balustrades

A beautiful combination of anthracite grey metalwork and dark walnut treads.  We were commissioned by an award-winning architect to manufacture and install this feature staircase in Chigwell, Essex.

Beautiful walnut treads with anthracite grey metalwork

Our client and architect wanted a mono-stringer staircase that was the main feature to the entrance of this grand property. It needed that wow factor – and we were able to deliver!

The stair treads were supplied in dark stained walnut to match the beautiful timber work in the property. The riser gaps were maintained to allow for maximum light (along with the stunning structural glass balustrade in 21.5mm thick toughened and laminated glass)
