All metal rail system.
Handrail mounted on top of glass. Nice marriage of wood, glass, stone, metal.
Interesting collection of elements w/desk, shelving, concrete, wood, angles. Concrete portion of stairway unsafe due to corner and lack of rails.
Nice look yet not necessarily for your home.
Wood handrail or metal handrail? Wood is warm. In time, generally a long time, maintenance required. Metal is cold. Little if any maintenance. Neither is right or wrong. Which do you prefer visually?
Glass and metal mix.
Iron options are abundant.
Another nice example of a square painted baluster. Again, how it is paired with other elements of stairway can make it go more modern or traditional.
Painted, square balusters are timeless. Very transitional style that can go modern or traditional depending on style of other components such as newel post, handrail, and base.
Again, horizontal look is clean, modern. Hazardous, however, for children.
Horizontal treatment nice, modern approach. If relevant, consider ladder look that encourages little ones to climb.
Mix of metal, wood and painted surfaces. Stair tread and floor tie in.
