This spiral staircase was supplied to a customer building a subterranean house in Loudwater, Rickmansworth. The property was build around a central square void which housed our external spiral staircase. The roof of the property was effectively their garden with grass and vegetation leading to woodland on three sides.
The spiral staircase was supplied fully galvanised before going through the powder coating process to ensure no corrosion. The treads were constructed with frosted glass and the balustrade was made up with vertical 316 grade stainless steel spindles and a stainless steel handrail. Along the platform, and running horizontally around the entire central void was glass balustrade with brushed stainless posts and handrail.
