Floating staircases in Metro Vancouver.
Mono stringer, cantilevered, hidden double stringer, and suspended floating stairs — a working planning hub from a Vancouver custom metal stair fabricator.
Floating staircase is a visual category, not a structural method.
The same finished photo can hide four very different stairs. A mono stringer carries the treads from a single central steel beam. A cantilevered stair anchors each tread into the wall behind it. A hidden double stringer tucks two stringers inside the tread profile. A suspended stair hangs from the upper structure. Each one demands a different conversation with the framer, the engineer, and the budget.
This hub keeps those decisions organized so a Vancouver project team can pick the right support method, plan the framing and engineering early, and finish the stair without rework.

Four ways a floating stair stays up.
The aesthetics follow the structure, not the other way around. Choose the method before drywall.
Mono stringer
A single central steel beam carries the treads from beneath. Treads cantilever equally on both sides. Visible spine, open risers. Most predictable to price and coordinate.
Cantilevered
Treads anchored into the wall through hidden steel back-plates or stud-packs. No visible stringer at all. The wall must be engineered before drywall.
Hidden double stringer
Two stringers tucked inside the tread thickness. Reads as floating without committing to an engineered cantilever. Honest middle ground.
Suspended
Treads hang from steel cables or rods anchored to a structural beam, ridge, or concrete deck above. Beautiful in the right space, expensive when the upper structure was not planned for it.
What this hub answers.
A floating stair is delivered into a building that is mostly finished. The decisions that matter happen long before install day.

Common questions before quoting.
What is a floating staircase?
A floating staircase is any open-riser stair where the treads appear to hang in space without obvious support. It is a visual category, not a structural method. Floating stairs use four common support strategies: a mono stringer (single central beam), a cantilevered system (treads anchored into the wall), a hidden double stringer, or cable-and-rod suspension from the upper structure.
Are floating stairs allowed in BC?
Floating stairs are permitted under the BC Building Code and the Vancouver Building By-law when the structural design, the open-riser provisions, the guard system, and the handrail meet the applicable code edition. Confirm specific requirements with your local authority having jurisdiction (AHJ) before fabrication.
Which floating stair option is most cost predictable?
A mono stringer floating stair is usually the most predictable to price. The single central beam, the brackets, and the connection details all live inside the stair package and can be reviewed by the engineer from a single section drawing. Cantilevered stairs unlock additional coordination with the framing trade.
Do floating stairs need an engineer in Vancouver?
Most custom floating stair projects require sealed engineering for the tread connections, the central beam or wall embeds, and the anchor points. Cantilevered and suspended stairs almost always need a structural engineer of record. We coordinate with the project engineer or define the information an engineer needs to review the stair scope.
What is the difference between a floating stair and a mono stringer stair?
A mono stringer is one specific support method — a single central steel beam carrying the treads. Floating stair is the broader visual category that can use a mono stringer, a cantilevered system, a hidden double stringer, or a suspended system. Most floating stairs in Vancouver custom homes are mono stringers.
