Impressive Exterior Floating Stair Ideas
Exterior floating stairs provide egress from your home as well as allow easy access from a raised deck to the ground level of your property. When deciding on the type of stairs for your outdoor space there are many styles and material options available that will complement the design of your residential or commercial property.
Like interior stairs, exterior stairs need to meet required building codes. For example, a landing would be required for any stair that is higher than 12 feet vertically. Building codes vary by state and municipality so it is important to check local building codes for requirements. For example, in most localities, a 36″ high guard rail will meet building codes however in California a 42″ high guard rail is required on stairs.
Exterior stairs need to be engineered to accommodate environmental influences. Tread materials that can withstand the elements are an important factor. The metal structure required for a solid stone tread would differ greatly from that required for a composite tread, a solid wood, or tile tread. The composition of the earth will determine the lower level stringer footings and anchoring requirements. These factors must be carefully considered to ensure a long life for the staircase.
Choosing a floating stair style is totally up to your design aesthetic, we offer a variety of stringer styles, powder-coat colors, and railings to mix and match to achieve your objective.
Exterior Floating Stairs are functional and beautifully complement any home’s architecture. See several inspirational and impressive exterior stair ideas below.
Modern Exterior Mono Stringer Floating Stair
The Summit Club is a private residential community located in Las Vegas Nevada that boasts 5-star amenities and views of the Red Rock Canyon. The design of the residences offers a variety of outdoor living spaces with large patios and decks for relaxing or entertaining. For this two-story Dessert Villa, we designed an exterior floating stair to provide access from the patio to the second story.
We collaborated with Discovery Builders on the design of the exterior stairs and railings for this project. The stairs are engineered to support the weight of the travertine treads including custom tread supports. The railing posts are connected to the stair stringer below the treads to prevent stressing the stone treads. The stair stringer is made of square steel tubes with the stair configuration incorporating two landings. The curved cable railing posts continuously wrap the stairs and deck. The posts design tapers to the top and has a round stainless steel handrail. Hidden wire channels are built into the steel structure of each tread to provide LED lighting on the leading edge of each tread.

We crafted the exterior stairs with double stringers made of C-channel and a horizontal round bar railing system. The stair treads are made of 1-1/2 in x 3 in IPE slats with space in between each board resulting in a wood grate appearance. Custom tread supports were designed on the stringers to support the unique wood tread design. The exterior railings have a simple sleek look with black metal balusters and horizontal round bars.

The spiral stairs are designed to have entry points at the ground level, on each deck, and on the rooftop. In addition, there are two matching floating stairs to the main deck allowing for easy access to the water level of the home.

To access the pool and complement the home’s architecture the client chose a floating mono stringer stair with stone treads. The stair and tread supports are engineered to support the weight of the blue-stone treads with the railing posts attached to the stair stringer. The stringers and railing posts are powder-coated to match the home’s accent colors. To maintain the views cable railings were chosen to wrap the decks, floating stairs, and screen porch.

Exposed Stringer Cantilevered Floating Stair
A post and beam home was disassembled and moved to a new location on top of a mountain in Stowe, VT. Each section of the home was labeled and numbered for easier reassembling in the new location. Since the client lived in the home for many years they knew what changes they wanted to make to the overall plan of the house. So they decided to take this opportunity to redesign part of the interior floor plan and added exterior floating stairs to the deck.
We designed an exterior floating stair system with robust steel stringers. The steps cantilever off the stringer on one side of the stairs, and transition to the other side at the landing. The cable railing system is our Ithaca style in stainless steel with a wide IPE wood top rail. The railing posts are fascia mounted to the deck and stairs.

Exterior L-Shape Floating Stair – Log Home
Located in the Catskill Mountains, NY, a weathered and damaged deck needed to be completely refurbished. Our client chose to replace an old split log style deck railing system with a framed metal cable railing. They were looking for a system that would hold up better to the natural elements of the area. The existing heavy log railing impeded their views of the mountain range so a cable railing seemed like the perfect choice.
This railing is custom-designed with 3-inch square tube posts giving the railing visual mass that complements the large timber log structure. They also decided to add a floating staircase for easy access to the ground level. The floating stairs have a large rectangular metal tube stringer with metal tread supports and a landing partway down the stairs. The treads, decking, and top rail are made of composite material.
