The client for a private house in Irpin received a finished product from a single contractor, without the need to coordinate three separate teams. We handled the entire process of designing, manufacturing, and installing the cantilever stairs: the load-bearing metal frame, solid ash wood treads, laminated glass railing, and contour LED lighting for each tread.
Here, the "floating" stairs are not just a design feature, but an engineered structure where every element contributes to strength and safety.
For projects of this caliber, the main difficulty is not the product itself, but coordinating the contractors. Metalwork is done by one contractor, woodworking by another, and glass by a third. The interfaces between their responsibilities are risk zones: mismatched dimensions, misaligned embedded parts, scheduling conflicts, and ultimately — claims that no one can be held accountable for.
We handled the full scope:
• Design and engineering calculations;
• Manufacturing of the load-bearing metal frame;
• Installation of the frame with embedded elements;
• Electrical wiring for the lighting of each tread;
• Manufacturing and installation of wooden treads;
• Glass railing;• Wooden handrail.
The client communicates with a single team that is fully responsible for the outcome — from the initial sketch to the final installation.
We begin work on the staircase with a complete working design: plans, sections, and fastening details. This allows us to install embedded elements during the rough construction phase and ensures that metal, wood, and glass will fit together perfectly without rework.
The load-bearing step frames are made from profiled tubing, welded, and primed in our own production cycle. The precise geometry of each element is established at this stage, as it determines the evenness of the future steps.
A 10 mm thick embedded steel plate is attached to the wall using chemical anchors, to which the load-bearing structure is then welded. The steps are cantilevered, with no visible supports from below, creating the effect of "floating" stairs. Installation was carried out concurrently with rough-in work.
The steps are made from veneered plywood with a final ash veneer. A separate task was to precisely match the wood texture and toning to the parquet flooring in the house. Together with the project designer, we produced several stain samples and selected the optimal warm walnut tone, which maintains material unity throughout the space.
The key engineering feature of this project is that the glass here is load-bearing. It doesn't just enclose the opening; it connects the steps to each other and binds the structure into a single rigid unit. This is why the railing is made of laminated tempered glass (ESG).
• Safety: Even if one layer is damaged, the second remains intact — the structure does not instantly lose its load-bearing capacity.
• Reliability: Laminated glass withstands constant operational loads because it is part of the structural system.
For the glass, Diamant brand (low-iron) was chosen — without the characteristic green tint of ordinary glass. In the interior, such glass looks clearer and doesn't draw attention, allowing the wood to remain the focal point. The panels are point-fixed with wooden plugs made from the same solid wood as the steps, without metal posts.
Our team routed the electrical wiring for each step — the LED strip is integrated into the edge, providing a soft, contoured light accent. We prepared the wiring for each step and brought out a central harness; the connection to the electrical panel and control was handled by the site electrician. This meant that this entire component remained under the responsibility of a single contractor, avoiding additional coordination.
A wooden handrail made of solid wood, with a 40x40 mm groove and matching the steps, is installed over the glass. The handrail is not just for aesthetics: it makes using the stairs more convenient and adds reliability to the structure compared to a railing without a handrail.
The finished staircase became the focal point of the double-height space next to the panoramic glazing. Massive wooden treads, clear glass without steel posts, and contoured lighting create the effect of a structure floating in the air — all while maintaining full engineering reliability. The client received a complete product from a single team: with no gaps in responsibility, no intermediaries, and no risk of sizing issues.
Art Solution designs and implements cantilever stairs, glass railings, and transparent structures from start to finish — turnkey. We handle metal, wood, glass, and lighting, so you work with one team, not three contractors.
