The Z-shaped staircase sits inside a stripped-back ground floor where one hall opens into the main rooms. Because there are no closed corridors to hide it, the stair reads almost immediately: a folded run of oak treads, wrapped by curved plaster walls, with the black steel handrail tracing the turn. The geometry is clear from several directions, and the stair becomes part of the way the house is read rather than a separate object in it.

A stair that holds the centre of the ground floor

With the lower level left open, the staircase stays in view from the kitchen, dining area, and other connected spaces. That open-plan stair view gives the composition its weight. The curved plaster walls frame the opening and soften the edges of the void, while the underside of the stair is finished in the same curved plaster treatment. The result is a single continuous volume, not a stack of parts. Light and shadow move across the curves, making the stair change character during the day.

From above, the opening reads as a sculpted cut-out in the floor. From the side, the Z-shaped staircase shows its change of direction more clearly, with the flight turning in a measured sequence rather than breaking sharply. The plaster surfaces keep the edges quiet, so the profile of the stair remains the main visual line. That shape is what ties the different viewpoints together: front, diagonal, and overhead all reveal the same folded movement.

Curved plaster walls around the stair opening

The curved plaster walls do more than frame the staircase. They guide the eye around the opening and give the stair a softer perimeter than a square wall finish would allow. The rounded lines are visible not only at the sides, but also underneath the stair, where the plaster follows the underside in a curved form. This treatment makes the structure feel drawn, almost as if the geometry was traced by hand before it was built.

White plaster also gives the stair a bright setting without drawing attention away from the materials. In the images, the wall surfaces catch daylight in different ways, especially where the opening deepens and where the curve turns inward. Those shifts matter because the stair is not placed against a flat backdrop. It is held inside a shaped envelope that directs both movement and view.

How the opening reads from the room

Because the ground floor is open, the stair opening stays legible from multiple points in the house. It is not tucked into a corner. The curved plaster walls set a clear boundary, but they do not close the volume off. That is what gives the Z-shaped staircase its presence: the stair can be seen while moving through the home, and the route up and down becomes part of the interior layout rather than a hidden function.

Oak stair treads set against a pale floor

The oak stair treads were matched to the oak floor chosen elsewhere in the interior, so the stair reads as part of the same material field. The wood grain is visible on the treads, especially in close-up, where each step shows a clear surface and a crisp edge. Against the pale plaster, the oak brings a warmer tone without changing the quiet scale of the stair. The material choice is simple, but it does important work in the room.

The tread rhythm also reinforces the Z-form. Each step lifts the eye a little further along the bend, and the diagonal view lets the sequence of oak surfaces read as one continuous run. In that sense, the oak stair treads are not only a finish; they shape how the staircase is experienced. The wood gives the stair its cadence, while the surrounding plaster keeps that cadence visible.

Light from above and the dining area below

A skylight above the staircase throws daylight into the space and reaches the dining area beside it. That light opening changes the atmosphere around the stair without adding another architectural layer. It sharpens the edges of the plaster and brightens the top of the void, while the lower rooms remain connected to the same source of light. The stair therefore sits in a field that is both open and lit from above, which helps the oak treads and white plaster register clearly.

The black steel handrail as a thin line through the curve

The black steel handrail stays deliberately slim. It runs along the curve without bulky rosettes, so the line remains clean as it turns with the stair. In the detail images, the fixings are visible, and the railing structure reads as part of the composition rather than an afterthought. This stair handrail detail matters because it marks the transition between the solid plaster envelope and the moving route up the staircase.

Seen against the white plaster, the dark handrail does two things at once: it defines the edge of the stair and it sets up a sharp contrast that makes the Z-form easier to read. The rail follows the changing direction of the steps, then disappears into the next section of the run. That restraint keeps the focus on the stair itself, on the curve, the tread pattern, and the way the opening is held in the room.

There is also a practical clarity to the layout. From the kitchen, the stair gives direct access to the upper floor and the cellar, so the route is embedded in daily movement rather than treated as a separate passage. The open-plan stair view, the oak stair treads, the curved plaster walls, and the black steel handrail all support that use. Nothing is overdrawn. The staircase does the work of connecting levels while remaining the strongest visual line in the interior.
