Straight-flight stairs

In residential installations, the most common solution is to use a straight flight of stairs in a single flight, because this is almost always the most efficient and economical way to achieve the necessary rise. The stair can be concealed to some degree behind a partition or set against one of the walls. This removes the necessity to provide balustrade on both sides of the stair, further reducing the cost and the footprint of the stair. This is the most commonly installed format of stair in Arden's residential projects.

While a straight-flight staircase is the simplest layout, it by no means should be interpreted as a least interesting approach. Many of the most exciting staircase designs such as the Z2 zigzag stainless steel stringer, or a cantilevered tread stair, are best suited to a straight flight format.

The Z2 zigzag mono-stringer is best suited to straight flights

Straight-flight stairs with landings

Straight-run stairs with landings are the most suitable for great heights. The landings allow the users to rest without breaking the rhythm of their ascent. In long staircases it is sometimes necessary to use several landings to break the climb. Many of Arden's commercial projects utilise this approach. Each landing included obviously increases the overall footprint of the stair, as space is consumed without a corresponding increase in rise. However straight-flight landings are generally slightly more efficient in terms of space than L or U shaped landings.

Why straight flights might not be specified

When straight flights are not used, it is usually due to issues around the space available for the stair. A straight flight may consume less space than (for example) a U shaped flight, but the footprint is relatively long. When a long footprint simply does not fit the architectural constraints of the building, more complicated formats are considered. Sometimes more complicated formats are preferred purely on grounds of the design intent. For example, a sweeping sinuous effect may be desired, leading to a curved or spiral design being used.

This spiral design was preferred over straight-flight formats purely on design criteria.
