Outdoor stairs must work in all types of environmental conditions and provide comfortable and safe ascents and descents, for all people: young and not so young.
Within the STAIR MODELS , we find the exterior stairs or also called exterior stairs.
Exterior Stairs Measurements
One of the most important aspects to consider when designing outdoor stairs (besides being safe and functional), is the proportion in the design, related to the other architectural elements around it.
Another aspect that should be considered is that, as they are outdoor stairs, people tend to use them in a more agile way, let’s put it that way.
In open spaces, with fewer obstacles (physical and sensory), you usually go up and down the stairs more quickly, which must also be taken into account when creating them.
In general, wider stairs would look more elegant and safer, but the context in which they are built must also be taken into account.
In the design of an external staircase, it is recommended that the risers be about 15cm, with treads of 30 to 31cm. This allows having a stair inclination that is very comfortable for all types of people.
In turn, from the design point of view, they are more attractive than stairs with steeper slopes.
Another important aspect to have a safe and functional outdoor staircase is the width of the landing and its length.
Landing from a ladder is a flat landing between different branches or sections, which allow the user to go up and down more easily. The relief of the terrain or topography plays an important role in the design of landings.
To build the landing of an exterior staircase, you must keep the following in mind:
- The length of the landing must be at least 1500mm, for external stairs.
- There should be a landing every 10 steps if possible, to lessen the effort required to climb outside stairs.
Exterior Concrete Stairs
The following example shows a fairly well-proportioned outdoor staircase for the entrance of a house. Undoubtedly an elegant model that emphasizes the entrance that is sized according to its function.
The next one is also appropriately designed, without wanting to attract attention, but which blends perfectly with the animal sculptures on each side, with the same material, texture and color. The striking element is the front door.
The following image shows an exterior concrete staircase for the entrance to a classically designed building.
It is noticeable that the façade of the building has undergone some changes or modifications (in the carpentry, blacksmithing, divisions), which means that the staircase no longer looks so well inserted within the whole, despite having a proportionate appearance and elegant.
Following we see two very different photos in terms of the construction model. The first corresponding to a building with a colonial façade, where there is an intention to achieve unity and harmony.
The second ladder image corresponds to a common example of poor construction. It should be noted that the dimensions of this example of an outdoor concrete staircase are not adequate, or at least do not look good visually.
Especially the thickness of the stair slab, although it manages to support the loads of use (leaning on a wall) it does not have a homogeneous thickness, while its dimensions and proportions are not adequate and cause a bad impression at the entrance of a building. .
Stairs at the Entrance of the House
Next we see a facade of colonial design with a semi-circular concrete staircase. The formal expression is pleasant, despite the deterioration and little maintenance of the building.
However, we see that the external staircase to enter the house does not have a sufficiently wide landing, which could cause some imbalance. It doesn’t really convey much security.
In this photo, you can see a staircase with a similar design, but that does have a landing, before entering the house.
Another example of an outside staircase. In this case we see a very elegant and striking model, evidently in a region with a cold climate (because of the black color).
However, it is also evident that its design lacks railings and intermediate rest, therefore, it is not a safe and comfortable external staircase.
The following two examples show an inadequate design of exterior concrete stairs to enter a house, for the reasons already stated.
Outside Staircase at the Entrance of the Well Designed House
The following outdoor staircase photo is a good example of design. It can be seen that it has a rest every 9 steps in addition to the metal railing to improve safety and comfort in its use.
This example shows a modern construction with the exterior concrete staircase of several flights with landing. A good example.
Next image of a well-designed outdoor concrete staircase, with a landing and railings on both sides. In addition, its formal design blends perfectly with the facade of the house, emphasizing its main entrance.
Next, we have a small staircase to enter the terrace or balcony of a house. It is small but well built, with metal railings on each side and a slope to climb comfortably.
This is a minimalist example. Highlights the sobriety in the general design of the façade. By covering a difference in level that is not more than 600mm, it does not require railings.
Another image of an exterior concrete staircase for the entrance to the house. A simple model that meets comfort standards. It could have at least had a railing on one side, to improve its security.
Another apt example, with the steps getting smaller as we go up. It is a model that forms a kind of pyramid, and at the end, the rest, which is part of the terrace.
The following image of an exterior staircase has a modern and minimalist design. It has a landing every 6 steps, which is very good. It might be advisable to place railings (with a minimalist design as well), at least on one of its sides, since it involves several flights of outdoor stairs continuously.
A very simple model of an exterior cement staircase, with just 3 steps and decorated with potted flowers and finished in stone and hydraulic slabs. I don’t think you need anything else…
