Open Designs

More than the use of a single stringer to add to the minimalist appeal, this stair also employs an open tread design to give it an open and modern feel.

Rich Accents

While the overall structure is modern and open, there are still a few elements to give the stair a traditional and elegant flavor such as the solid wood handrails and treads made in-house by our professional wood shop.


Custom Cut Stringers

Each stringer is made to match a specific space, so your stair will have a custom fit that matches the exact dimensions of your project.
