Interior steel stairs with timber

Interior stairs are a daily-use detail and a structure at the same time. This realization shows the NICOS character clearly: steel should stay technical, but proportions, light and finish must remain domestic.

Parameters

Location: residential interior
Scope: stair flight, railings, mezzanine, handrails
Material: black steel and timber treads
Finish: matte black powder coating
Year: 2024

Challenge

Introduce a steel element into the interior without losing the warmth of timber or creating a visually heavy railing.

Solution

Slim steel beams and horizontal railings were paired with timber treads and a warm wooden ceiling.

Result

The stairs become a central interior element without dominating the light and materials of the home.

Technical

—stringer or cantilever structure depending on site
—steel railings with horizontal rhythm
—timber treads on steel structure
—matte black matched to interior details

Process

01
flight geometry and tread-height definition
02
support and mezzanine point verification
03
structure, tread and railing installation
