A straight staircase can be defined as one having a single, straight flight of stairs like a ladder that connects two levels or floors in a building. A straight staircase is one of the oldest and most common types of staircases found in buildings.
Lack of privacy: Because there is no visual barrier between the two floors connected by a straight staircase, there is often a lack of privacy. This is sometimes awkward in buildings that house multiple families on different floors.
Falls can be Serious: A straight staircase often consists of more treads than a staircase with landings. As a result, a fall from the top of the stairs could result in serious injuries.
Uncomfortable for older people: The lack of a landing can be tiresome for older people who have to climb all the stairs at once.
Requires More Space: Straight staircases require more linear space as compared to curved or platform staircases.
Or the stairs have “closed” stringers that does not show the profile of the steps. In this case the steps are supported by what looks like two straight, solid beams running at the bottom of the balustrade.
FOLDED-STRINGER STRAIGHT STAIRS: Sometimes the stringers are folded like in the image here below.
OPEN-RISER STRAIGHT STAIRS: Nowadays, open stairs which have open treads, that is without risers, are more popular since the form of the staircase can be seen from all angles. See picture below.
CENTRE STRINGER STRAIGHT STAIRS: Another way of supporting the treads in straight stairs is with one central stringer. These are called centre-stringer stairs (mono-stringer stairs). Normally, the steps in this type of staircase are open so that the central stringer is highlighted. See here.
CANTILEVERED STRAIGHT STAIRS: In some cases, there is no visible stringer and the steps appear to cantilever out of a wall (see the image below). These are called cantilevered-stringer stairs. In this type, usually there is a concrete or steel stringer embedded within a wall, to which the treads are fixed.
CARPETED STRAIGHT STAIRS: To enhance the straight line of the stairs, sometimes, a carpet runs along it’s length.
The stairs shown in this post are just a few examples. Innumerable types are possible with the imaginative use of different materials for the treads, risers, stringers, balusters and railings.
