At Palm Beach Floating Stairs , we install custom floating stair systems in Palm Beach, FL — including estate homes on Palm Beach Island, CBS-construction houses throughout North County, and commercial properties in the West Palm Beach corridor.

Retrofitting a floating stair into an existing Palm Beach estate requires more than good fabrication. You're dealing with CBS walls — concrete block with stucco — not standard wood-frame construction. Standard epoxy anchors don't behave the same way in solid masonry as they do in a stud wall. We core-sample the CBS before designing our anchor pattern, then specify Hilti HIT-RE 500 adhesive anchors rated for the actual substrate density we measured on site.

Many of our clients are in Addison Mizner homes on Ocean Boulevard and North County Road. The architecture demands a staircase that respects traditional proportions — not an ultra-contemporary floating slab. We work with classical baluster profiles, wrought iron rail systems, and stone or hardwood treads that sit harmoniously inside a Mediterranean Revival foyer rather than fighting against it.

Palm Beach Island falls under dual permit jurisdiction. The Town of Palm Beach building department handles your permit, but any exterior-facing element or structural modification to a landmark-eligible property may also require ARCOM sign-off. We know when to flag ARCOM review early, which keeps your timeline intact.

On the oceanside of A1A, salt exposure is a different problem than on the Intracoastal. We specify hardware differently for each. Ocean-facing properties get 316L stainless for every exposed fastener. Intracoastal-facing jobs often use marine-grade powder coat over galvanized substrate, which holds up comparably at lower cost. We don't apply one spec to every job.

Custom Floating Stair Installation Options

We build floating stairs in every structural configuration suited to Palm Beach homes and commercial spaces:

Mono-Stringer Systems
A single central steel beam supports each tread. Works well in narrower stair openings where a tight wall-to-wall fit is required. Common in Palm Beach town homes and guest houses with limited corridor width.
CBS Wall-Anchored Cantilevered Systems
Treads bolt directly into the concrete block structure — no visible stringer at all. We core-drill and epoxy-anchor into the CBS at each tread position, distributing load across multiple anchor points.
Double-Stringer Systems
Two parallel stringers handle wider treads (48 inches or more) or heavier commercial loads. Suited to grand foyer openings in larger estate homes where a 42-inch single-stringer would look undersized.
Traditional Profile with Modern Floated Treads
For Mizner-era estates and classical Palm Beach interiors — we combine a concealed structural system with traditional baluster profiles, turned newels, and stone or hardwood treads that match the home's existing language.

Our Process

How We Deliver Custom Floating Stair Installation

Floating stair installation in progress at a Palm Beach residence
01
Site Assessment & Substrate Verification
We visit the property and core-sample the CBS walls to determine actual masonry density and block configuration. This isn't optional — it's what every anchor calculation depends on.
02
Structural Engineering & Jurisdiction Review
Our engineer stamps drawings to Florida Building Code standards and flags any ARCOM triggers for Town of Palm Beach properties. We identify dual-jurisdiction requirements before permit submission, not after.
03
Fabrication & Pre-Fit in Our Shop
All steel components are fabricated, finished, and dry-fitted in our facility before delivery. For estate projects, we bring samples of tread materials and hardware finishes to the property for client approval first.
04
Installation & CBS Anchor Execution
We core-drill anchor positions, inject adhesive, and set the anchor rods before installing the stringer or tread brackets. Each anchor is torque-tested before any load is applied.
05
Final Inspection & Permit Close-Out
We coordinate the required building inspections — including any special inspections for anchorage if required by the engineer — and close the permit. You get a copy of the stamped drawings for your property file.
Common Questions

Custom Floating Stair Installation — FAQ

How much does custom floating stair installation cost in Palm Beach?
A straight cantilevered system in a Palm Beach residence typically runs $18,000–$45,000 installed, depending on tread material, rail system, and how much CBS wall reinforcement is needed. Estate homes with curved profiles, stone treads, or decorative ironwork run higher. We give you a fixed-price proposal after the site assessment.
Do floating stairs in the Town of Palm Beach need ARCOM approval?
Sometimes. Structural changes inside the home don't automatically trigger ARCOM, but if the staircase is visible from the street or the project touches an exterior element on a historically designated property, ARCOM review may apply. We determine this at the design stage so it doesn't catch you mid-permit.
Can you anchor into CBS walls instead of wood framing?
Yes — that's actually the most common wall type we work with in Palm Beach. We core-drill the block at each anchor position and set adhesive anchors rated for the specific masonry density. The hold-strength in solid CBS is typically higher than wood framing, which works in the design's favor.
How long does the permitting process take in Palm Beach County vs. the Town of Palm Beach?
Palm Beach County residential permits typically review in 10–21 business days. The Town of Palm Beach's building department is smaller and generally faster — often 7–14 days for a residential structural permit. If ARCOM review is also required, plan for an additional 4–6 weeks for that board's meeting cycle.
Can floating stairs work in a traditional Palm Beach home without looking out of place?
Absolutely. We've installed cantilevered systems in Mizner-era estates where the treads are limestone, the rail is hand-forged wrought iron, and the hidden structure supports the look while completely disappearing from view. The floating mechanism is invisible. The aesthetic is entirely about the materials you choose.
