Floating Staircases
Treads that appear to hover in mid-air — concealed engineering, dramatic effect
Floating Staircases
Floating staircases — also known as cantilevered staircases — create the illusion of treads suspended in mid-air with no visible support beneath. The effect is dramatic, contemporary, and unmistakably bespoke.
Each tread is anchored by concealed steel brackets embedded into the wall or a hidden metal stringer during construction. The brackets are engineered to carry the full structural load while remaining completely invisible after plastering.
MOLTURI floating staircases are structurally engineered to meet UK building regulations. We design open-tread, closed-tread, and hybrid configurations depending on the architectural brief. Glass balustrades are a popular pairing — the transparency maintains the sense of lightness that defines the floating form.
As treads are spaced, natural light flows through the staircase, brightening the space and making rooms feel more open. Floating staircases are popular with new builds and renovations alike, and can be manufactured in glass or solid hardwood.
Common questions about floating staircases
How are floating staircases supported?
+
Each tread is supported by concealed steel brackets embedded into the wall during construction, or attached to a hidden metal stringer within the wall. The brackets are engineered to carry the full structural load while remaining completely invisible after plastering. The result is treads that appear to float in space with no visible support.
Are floating staircases safe?
+
Yes. Floating staircases must comply with UK building regulations. The maximum rise for each step is 220mm and 150mm for the minimum. The tread width must be between 220mm and 300mm. Handrails are required on at least one side if the staircase is less than one metre wide, and on both sides if wider. Every MOLTURI floating staircase is structurally engineered with detailed calculations submitted to building control.
Can floating treads be added to an existing wall?
+
It depends on the wall construction. Solid masonry and reinforced concrete walls can typically support cantilevered treads directly. Timber-frame or stud walls usually require a concealed metal stringer to be embedded in the wall for structural support. We assess this during the consultation and work with structural engineers to ensure full compliance.
Why choose a floating staircase?
+
Floating staircases are popular for their stunning visual effect and practical benefits. As the treads are spaced, natural light flows through the staircase, brightening the space and making rooms feel more open and spacious. You also gain usable space beneath the staircase — for storage, decoration, or simply an open floor plan. They work equally well in new builds and renovation projects.
Can floating staircases be made from glass?
+
Yes. Glass treads combined with a concealed steel support system create a particularly dramatic floating effect. The transparency allows maximum light flow through the staircase. We also offer glass balustrades alongside timber treads for a lighter look while maintaining warmth underfoot.
