Spiral staircases are not only aesthetically pleasing; they can also serve a variety of needs and purposes. Acadia Stairs has worked closely with many clients to help create custom, modern and contemporary spiral stairs for their home or commercial building.

With years of industry experience, there is not a job too big or too small for our company to handle.

Clients most often use our modern and contemporary spiral staircases, equipped with a center pole, as stairs for a loft or basement, or we can create larger ones for commercial projects. However, the options are limitless if this is a look you want to feature in your home or business. Additionally, we make curved staircases, without a center pole, and they have a nice sweeping look to them.

Please see the pictures and descriptions of our examples below for a better indication of the type of spiral staircase designs we can do for you. Also, please keep in mind that our stairs are built precisely to shop drawings, ensuring our customers receive exactly what they had in mind.

This 8 line rail stair is a great way to accentuate the spiral look.

The lower lines are 3/4″ round for a lighter look and are spaced less than 4″ apart for safety.

We can provide wood tread covers in nearly any species.

Our standard tread is a select grade red-oak tread, finish sanded to receive your stain or clear coat finish.

We can also provide; white oak, cherry, mahogany, walnut, pine, plywood, or you can provide your own wood tread covers.


We specialize in custom made, modern and contemporary spiral stair kits.

Custom Made Spiral Stair KitsEach stair is tailor-made for the situation into which it will fit.

We work with you to make sure that the stair will fit your measurements, layout, codes, decor and of course your budget!

Custom made kit spiral stairs are great for interior applications. We fabricate the stair in our shop & pre-assemble the stair.

The stair is then shipped in knocked-down form. This makes the stair easy to get into the location and easy to put together.

We make simple spiral stairs with clean lines and an open look.

This stair features a 1 1/2″ round steel handrail, 3/4″ round balusters, flat plate treads with oak tread covers.

The railing on the upper landing and around the opening is custom made to fit the layout and dimensions of the project.

The 1 1/2″ round steel spiral railing is rolled to the rise & run of the stair. 2 balusters per tread reduce the spacing so that it is safer.

The riser sleeves are custom cut to the exact height needed.

The riser sleeves stack exactly on top of one another, creating a smooth look at the center pole.

This also allows the customer to finish paint the stair in a wide variety of colors. The oak treads are natural & must be stained or sealed before in the field.

Kit spiral staircases are easy to ship. When fully packaged, they only take up as much space as an average pallet.
