A straight staircase is the most common and affordable style available. The straight line design means that the staircase doesn’t need any special support and only needs to be attached at the top and the bottom. This type of staircase also allows for easier installation of railings and handrails. Of course, there are variations of the straight staircase that include open risers, modern materials and metal cable railings that significantly alter the basic look. While a straight staircase may be the most common, it does have a few drawbacks, namely that it takes up a greater amount of linear space, which can really affect your design.
L-SHAPED STAIRS (quarter-turn)
L-shaped stairs are another common style of staircase. They are basically a straight staircase with a turn, either in the middle or closer to one end or the other. L-shaped stairs are appealing for a variety of reasons, primarily because they are more visually appealing. In addition, they tend to take up less space and can be used in the corner of a room. For some people, they are also easier to navigate because of the wider landing that breaks up the flight of stairs. Of course, these types of staircases are more complex to build and consequently more expensive. L-shaped staircases also usually require support for the landing and the turn.
U-SHAPED STAIRS (half-turn)
U-shaped staircases generally consist of two flights of stairs that go in opposite directions with a landing at the switchback. These are also more visually interesting than a straight staircase. Moreover, they take up less linear floor space and can be handy for a corner design. Typically, the landing is of a generous size. The main drawback of a U-shaped staircase is the turn that makes it more difficult to move larger pieces of furniture upstairs.
Winder stairs are a lot like an L-shaped staircase, except that there is no landing. Instead, the stairs are continuous, taking on a wedge shape as they make the turn. These have been far less common in contemporary homes and are typically found in older residences. Rarely were they used as the main, front stairs and were more likely to be found as the second set of stairs in the home. This type of staircase is seeing a resurgence in popularity, thanks to the trends that favour smaller homes and more sustainable homes.
