Sep;21(3) Stairway risers and treads: acceptable and preferred dimensions. Irvine CH(1), Snook SH, Sparshatt JH. Author information. The builder must calculate the size of the treads and risers. The steepness of the stairs depends on the relationship between tread width and riser height.
Understanding the role of stairs in different spheres of human need and expression is crucial in approaching its design. The pattern of stairs is dependent on the type of materials and other related design considerations. It is one of the unique architectural entities that reflect the various facets of social, psychological, artistic, metaphysical and religious dimensions. The importance of physical activity in the rising sedentary life styles is linked to the design of building elements, especially the staircases.
The advancement in technology has displaced the role of stairs into an inconsequential means of emergency escape. But the importance of physical activity in the rising sedentary lifestyle has revitalized the concept of stairs as an active building component. The mono functional approach to staircases in high-rise buildings, especially as the means of escape in emergency situations, indicates that the design of staircases as multi functional element is still under the confines of design explorations.
This paper is an attempt to understand the concept of stairs not only from the evolutionary point of view, but also the associated metaphoric meanings and its emerging multi facet identity. The concept of vertical accessibility in the form of tread and riser arrangement makes stairs a timeless phenomenon. The approach to multi utility architectural elements stretches beyond physical functions and should integrate the various dimensions of space making and society.

In this regard stairs are a pioneering entity that has a potential to relate to many spheres of human thinking. What is this process of becoming, what is this relation and in what way is it visual, and how is the architecture transformed as a result? The answer to this kind of question lies not just in the constructional, visual or spatial analysis of the stairway, although 4 such things do play their part; the stairway can, of course, be seen in plan, section, elevation, photograph, working drawing, direct experience and all the other ways of observing a piece of architecture.
But such representations as plans and even sections do little to articulate the more dynamic aspects of architecture, particularly those involving verticality.
Although Ellis does allow for a certain poetic and sculptural quality in architecture, his analysis of buildings by Corbusier and Aalto discloses on over-riding concern with clarity of expression and a certainty of knowledge: We are therefore offered only limited clues here as to the more Golden Lane stairway might be such a central part of the flat as its construction suggests. At the Golden Lane it is when walking up and down, as one must repeatedly do during the course of daily routines, that one first encounters the unique phenomenological character of these stairs.
While the quotidian body may be transformed into that of a dancer through the device of the stairway, so too is another transformation effected upon the stairs themselves.
Stairway risers and treads: acceptable and preferred dimensions.
When experienced by the motile and rhythmic body, the treads are revealed as individual planes, each forward step being met by a corresponding, independently-supported platform on which to tread, and, simultaneously, as the steps continue, by a connected series of such planes; the stairs are at once unique and repeated, autonomous and integrated. Ascending and descending, combining bent knees, measured steps and a cautiously balancing hand for the Golden Lane stairway is unusually steep, a fact brought into sharp relief by the absence of solid risersone enunciates these stairs as a sentence, a chain of moments and movements each unique in itself yet inseparable from the others.
Walking creates a unity of the stairs; hence it is the act of movement together with the architecture, and, not the architecture by itself, which makes the stairway.
These stairs are as pearls on a necklace, complete qua necklace only when placed against the body. It is not, however, simply that the stairway is a production of bodily space and movement, for, as in Baroque stairs, it itself is also a focus of attention,12 an intellectual as well as material endeavour. At Golden Lane, just as walking unites the stairway and the stairway unites walking, so too does the stairway give aesthetic expression to the possibility of movement — each cantilevered tread, ever visible to the eye, suggests that walking on these treads is not only possible but probable, and hence that the floors of the flat are continually interrelated.
In further reinforcement of this view, the vertical metal balusters are, although evenly spaced horizontally, given a 1: Each tread is thus expressed 7 separately yet part of the series, with a dynamic composition subtly transferring the eye from one to another.
Through such aesthetic operations, the stairway offers the continual reminder that there are other spaces within the maisonette, and that habitation conjoins them together. The same could perhaps also be said of the double-height space which sits over the stairway, for this too gives volumetric connection between floors. Yet it is only the eye and not the body which travels in this space indeed, I have physically entered it only once, in order to complete a precarious piece of DIY.
Indeed, this facet of the stairway is revealed in the very naming of its parts, where the step, tread, going, flight and riser are, along with the door handle, near unique in architecture in being not only the noun given to the element in order to identify it but also the verb used to describe the bodily encounter with that element: This very nomenclature demands that an action, and an overtly bodily action at that, be performed against the element, such that its essence ultimately lies not within the material or form of the architecture but in its reproduction within the motile body and within the expressive means language and architectural design by which we represent that reproduction.
After living in this flat for a while, another connection also gradually makes its present felt. The stairs are made from hard terrazzo although in our home they have been covered with paint and tiles and when trod upon, each creates a distinct sound, such that 8 every descent and ascent provides a short, repetitive melody to the life of the flat — a keyboard of everyday movements, punctuating space with its peculiar form of music.

It is perhaps no coincidence that the hi-fi in our flat is placed beneath the stairway; unconsciously, this area has been made into the sound-hearth of the home. While there are no public stairway social condensers in the Golden Lane — those spaces beloved by the designers of social housing where residents are expected to unavoidably meet and thus forge new social relations — the internal stairways nonetheless act in their own small way within this social frame.
Each cantilevered tread is balanced by its mirror-element on the other side of the party wall, creating exactly the same stairway for the flat next door. And so my paced sound-rhythms are transmitted with extraordinary efficiency through the terrazzo to my South African neighbours, just as their sounds are to me, creating a sonorous and social connection between our otherwise separate existence.
After some years, I know when they sleep and when they arise, I know when they are in a hurry and when A. This, perhaps, is what is so intriguing about the stairway: What goes up must come down, what is moving is also rendered as aesthetic form, what is given is always returned.

The stairway may at first seem to be a linear arrangement, but in fact it is a transformative cycle, periodically rendering architecture and everyday life into a new and delightful composition.
