Bas Optimal has underlying stringers. It provides a simple, clean and light design that is always perceived as modern and timeless. A staircase with underlying stringers can both stand freely in the room and be built in with storage underneath.
In Bas Optimal you can choose between two different hand rails and to adapt the staircase wood and finish to your own taste.
Here is a straight staircase with risers with nose. Overlapping steps create more space for the foot, especially for the heel on the way down the stairs, our standard is 28 mm (see model Solid, built-in between walls).
