Spiral stair case

A square plan project makes some spaces fully exploitable by spiral staircases or square helical stairs

Stair solution ideas for interiors, especially particular structures and studied in detail, not only complete the design of the rooms but also they redefine it. And not only. The choice of internal stairs with anatomical structures of a type or other type define also the sizes and quantity of living spaces.

Among the modern design options and also space-saving options  we can count the square spiral stair case as well as the square helical staircase: both types (we will also talk about a “mixed” that is the helical-spiral) are based on a design concept that aligns the verticality, a somewhat spiralform trend, albeit rigid, and possible exploitation of angular spaces.

Both types, square indoor spiral staircases and square helical stairs, make the best use of space and, according to materials and finishes, can produce great aesthetic-functional results.

The project, construction and installation of stairs design are all delicate moments since this architectural element connecting different levels should be ideally integrated in the interior.

Depending on the general design you could opt for a staircase with cantilevered steps, a straight staircase with an exposed structure or floating stairs, spiral stairs, metal stairs, wooden stairs… In short, when it comes to indoor stairs and modern stairs there is only the embarrassment of choice.

If your focus is on a spiral stair case or a helical spiral stair, it’s probably for a number of specific reasons: in particular, the classic round spiral that unfolds with a spiraling motion around a central pole is the structure with greater possibilities of saving horizontal space, so much to be considered as a space-saving structure.

If the first instance is the optimization of the dimensions, the second could be aesthetic: clearly it’s always a matter of personal taste, but an indoor spiral stair has its own allure, given by the spiral effect that has something magical and fascinating, both at sight and during the ups and downs.

We know that there is a possibility to design, build and install a spiral stair case with a visual effect quite different from the same round plan. 

Not only the aesthetic result is different but also the use of space.

Very commonly square holes and a square stair solution make the most of an angular position, so in the presence of at least two walls: a square spiral staircase needs during the design of the same round precautions in relation to dimensioning, number of steps, step and step etc. but the anatomical shape will be different.

In particular, in a modern spiral staircase with a square plan it will be more comfortable at the same size since the steps in the corner portions enjoy every centimeter and at the same radius the surface of support is larger.

Of course, there is nothing to prevent square spiral staircases from being placed in central and non-angular positions if the broken lines and geometric design are particularly appreciated.   

Round-shaped spiral stairs and square-shaped helical stairs                                                 

Round-shaped spiral stairs and square-shaped helical stairs

Choosing a staircase for interiors, in particular shape and size, is an action naturally subject to various constraints: floor to floor space, for example, or the presence and placement of any compartments such as windows and doors. 

The width of the hole, the intended position of the stair etc are data necessary for an accurate design which can calculate depth of step, elevation, number of steps and so on: all this is aimed at the safety, in the foreground, of the structure, whether it is a helical or a spiral stair case, floating staircase or other types of internal stairs. 

Speaking of spiral-shaped helical staircases (without central column), in a sense modern evolution of the classical spiral staircases, we know that the floor plan base can be circular, square or even elliptical. For a square indoor helical spiral staircase (square metal staircase, square steel or stainless steel spiral staircase, wooden spiral and a wide range of quality materials materials of choice) the same speech is valid as the square spiral staircase.

Although the positioning as mentioned may have various constraints, it is not said that the placement of this type of spiral stair takes place necessarily in angular position (could be placed in the middle of a living room), but it goes without saying that this has its own reason for being.

A square indoor spiral staircase is undoubtedly comfortable, the ups and downs are more easy, not to mention that a spiral staircase gives its best as an aesthetic impact, not forced in minimum diameters; helical stair is not in line with a space saving spiral staircase except for vertical development.

But there is also more: we often find in the most current range of spiral stairs even a particular intermediate structure: this type of installation has a central pole, unlike the helical stair, but this pole is open.

This modern custom spiral stair case is also one of the possible spiral stairs variants to choose from, to save horizontal space and at the same time to equip the interior with a special object that draws the lines of a style, an incisive impression that fully represents you.

Creating a connection between different levels of a building (we can also talk about small loft stairs, why not) involves a functional side of course, but the issue is much broader: internal stairs, in particular, are now used as real furniture elements, in some cases they can be so valuable and special that they can almost be considered works of art.

The anatomical shape and use of quality materials, the colors, the contrasts added to significant details make up the whole project. Square, circular or elliptical spiral staircases as well as  very small spiral staircase structures are able to enhance or even change the atmosphere of the interior.

In some cases through prefabricated elements but more easily thanks to a tailored quality product, you could choose a steel spiral staircase, stainless steel, for example mirror polished or steel painted with standard or special sample paints. A painted metal staircase can be exploited in different ways: different colors for the structure or for special railings and handrails, as well as it is also possible to insert a wood handrail or curvilinear glass parapet, you could add special coatings to the step element or invest resources in a lighting suitable for an excellent quality spiral stair case.

Helical staircases or spiral staircases with square iron base can therefore become an essential and minimal structure of industrial mold but a metal spiral staircase can also take a completely different turn and disguise itself in another style, we think for example about an artisan forged iron spiral stair, what a different impact! Or let’s think of another example: the same structural form, the same steel spiral stair structure with glass railing, but coated with materials such as solid wood or stone material achieves a completely different result.

Beyond the optimization of spaces and sizes, a subject of no small importance, the more or less sinuous forms, more or less rigid in combination with the use of materials declined in light or dark colors, raw finishes or lacquered, dense volumes or stylized shapes will be the real outfit of your installation. The same goes for outdoor stairs, not only for indoor spiral stairs, but this is another story!
