A black steel frame and light wood treads set the tone as soon as the stair comes into view. The floating steel staircase reads lightly, even with the quarter-turn at the lower end. Slim treads keep the structure visually open, while the horizontal lines of the black steel railing guide the eye upward through the bright hall.

The brief was clear: a steel staircase with wooden treads, but the lower landing had to turn because of the plan of the space. That move becomes the most visible part of the composition. Instead of a straight run ending against a wall, the stair shifts direction and holds its line beside the glass wall. The result is practical in layout terms, yet it also keeps the stair visually sharp from the entrance.

Light treads, slim steel, and a clean profile

The treads are built as a steel and wood stair detail with a restrained thickness of just 50 mm. That thin edge is what gives the staircase its floating character. From below, the darker support recedes and the wood reads as a set of clean horizontal planes. The contrast between the black powder-coated steel and the lighter timber keeps the stair legible without adding visual weight to the hall.

Material choices are part of the expression here, not an extra layer on top. The project text mentions 10 mm laser-cut solid sheet steel and 40 mm solid oak, finished in powder coating 9005 fine texture. Those specifications explain why the stair can stay so slender at first glance. The oak brings a warmer surface underfoot, while the steel keeps the edges straight and precise.

A quarter-turn lower section beside glass

The quarter turn staircase at the lower side is not just a change in direction. It is the point where the staircase has to work around a glass wall, which means the treads cannot be tied back to the wall for support. That constraint is visible in the way the stair sits free of the glass and continues as a floating staircase with wood. The transition is compact, but it avoids any heaviness at the base.

In the photos, the stair sits next to glass and daylight, with a door and tall glazed surfaces close by. That setting makes the geometry easier to read. Each tread appears separated from the next by a dark shadow line, and the lower turn is clear without breaking the rhythm of the run. It is a small move in plan, yet it shapes the whole reading of the staircase.

Black steel railing with horizontal lines

The railing follows the stair in a series of horizontal bars, kept in black steel so the line stays quiet against the white walls. Those bars do more than mark the edge. They echo the direction of the treads and extend the stair’s horizontal movement across the frame. In several images, the railing becomes a drawn line that sits in front of the bright entrance rather than cutting through it.

Because the balustrade is dark and the hall is light, the stair keeps its outline even from a distance. The profile of the black steel railing is thin, but it still gives the landing and the run a clear boundary. That is especially noticeable where the lower turn begins and the glass wall sits close beside it.

Seen from below, the structure stays restrained

The underside of the treads is one of the most revealing details in the project photos. You can see the dark support and the way the timber projects beyond it, leaving a narrow shadow line below each step. That view matters in a floating steel staircase, because the impression of weight is controlled there. Here, the underside does not interrupt the reading of the stair; it supports it quietly.

Repeated treads create a steady rhythm through the hall. The white ceiling and bright wall surfaces keep the stair zone open, while a round ceiling light hangs above part of the route. The lamp adds a small focal point overhead, but the staircase remains the main line in the room. Its materials do the work: black steel, pale oak, and the clear edge of each tread.

Steel staircase with wooden treads in a bright hall

As a steel staircase with wooden treads, this project depends on contrast. The wood softens the visual hardness of the metal, but only just. The surfaces are still crisp, with straight edges and compact joins. That balance is what makes the staircase read so clearly in the entrance hall. There is enough warmth in the oak to break the dark mass of the steel, yet the overall impression remains sharp and ordered.

The hall itself stays secondary, which suits the project. High glazing, a door, white walls, and ceiling light only serve to frame the stair. The floating steel staircase becomes the route through the space, and every visible detail points back to that route: the lower quarter turn, the slim treads, the black railing, and the gap created by the wall of glass beside it.

This stair was made to solve a specific spatial problem without losing its visual lightness. The quarter-turn lower section answers the glass wall, and the steel and wood stair detail keeps the construction readable from the first step to the landing. What remains is a staircase that is direct in form and careful in proportion, with enough restraint to sit quietly in the entry while still defining it.
