There are a number of ways to build a floating staircase, and it all depends on the existing structure of your house.

How Do Floating Stairs Work?

Modern floating stairs with wood steps and vertical cable supports In most types of floating staircases, a load-bearing or structural wall is important, as it will be the one to provide support for your stairs.

Cantilever floating stairs, the most popular style, tend to rely a lot on the structural stability of the wall, as it does not have any additional supports underneath to create a clean modern look.

In the case of a non-load-bearing wall, however, there are still design alternatives that can be used to achieve this. The overall supporting structure of stairs will entirely depend on the wall structure and the engineering of your stairs will be designed accordingly.

If you’re worried about the stability of floating staircases, or your wall doesn’t provide enough support, you can also explore using central-spine staircases.

These stairs also have a floating look to it, but it has an additional central spine (usually steel, wood or concrete) to support its load, so you don’t have to worry about your wall.

The small gap further emphasizes its “floating” look, and keeps the walls free from damage.

One great advantage of quasi-floating stairs is that there will be no damage done to the walls, as the stairs support is attached to the floor and the ceiling slab.

There are many material options if you want to install floating stairs into your home. But always consider safety above all. If you have small children or pets in your home, free-floating stairs is definitely not a safe option as they usually don’t have railings.

Choose a design with utmost consideration to the safety of the users & the safety of the structure above all, and it will surely be worth it.

Free Floating Stairs

Free-floating stairs, also known as cantilever stairs, usually have a very slim and minimalist look. They usually require a load-bearing wall for support and their maximum stair width would depend on the design of its support.

Ideally, free floating stairs design (also known as cantilever stairs) should not be too wide to ensure stability, especially when using wood or other materials that easily bend.

Floating Wood Stairs

There are a couple of ways to install floating wood stairs. The most popular is cantilever wood stairs, you can also use a quasi-floating staircase (or central-spine) with wooden treads.

Always make sure you’re using the right type of wood, because not all wood species are made equal, and some are easier to warp and bend than the others. Choose the appropriate type of wood depending on the support structure of your stairs.

Metal Floating Stairs

Recently, there have been many creative techniques to use metal for stairs. Traditionally, they’re only used for structural support, or for railings. However, recently you’ll also find metal treads made from metal sheets, metal frames, and many other creative applications.

Floating Stairs DIY

While DIY stairs is completely possible, it is recommended that you have prior knowledge & experience in building/construction, as it requires a lot of technical know-hows.

If you’re confident with your skills, however, just take note of the following important points:

  1. Check the building code – make sure you take note of the minimum and maximum measurements and load requirements to ensure the safety and functionality of the stairs you are building.
  2. Asses support structures – are you building off a concrete wall? Drywall? Or is there no wall beside your stairs? These are all factors that will narrow down your choices for floating stairs supports and style.
  3. Determine the users of the stairs – if you have small children, pets, and elderly that will also use the stairs, ensure that the stairs you are building will be safe for them. Add railings for extra support, and if your kids or small pets like to run around a lot, perhaps a stair riser will also need to be added to avoid accidents.
  4. Choose the right material – all the above-mentioned factors will also help you narrow down the material choices for the stairs. Make sure you select appropriate materials and support hardware.
