These Auckland homeowners wanted an industrial style look for their interior home design. So when it came to building the staircase, handrail and balustrades, we knew the exposed steel in a matte black was going to be the right look for them. ​ Due to the double stringers and concrete treads, this style of staircase is extremely solid and has zero movement, massively reducing noise. Our biggest challenge on this project was that the double stringer staircase was designed with concrete treads that needed to be colour matched to the pre-existing floor.
