Cut-in handrail: Open-riser stairs between solid walls are common, as this photo and the previous one show. How to detail a railing is an important consideration in these types of stairs. An alternative to a railing mounted on brackets is one “cut” into the wall, a more difficult and expensive design, but one in keeping with the minimalism of the overall stair. Of course, as many of these photos show, having a handrail is not a guarantee that anybody will use it!
