Closed String Staircases
Closed String Staircases are a great alternative to Cut Strings. They come with the advantage of not having any visible treads from the sides. They can have softwood treads and MDF risers for full carpeting & painting or manufactured in hardwood. The balustrades can be in wood, metal or glass.
These stairs can be designed in various forms, including straight, spiral or helical shapes, no matter how elaborate it needs to be. If you are searching for inspiration to helical staircases, please consider checking out the helical section for more examples.
