2024 - SYMPHONIC STAIRCASE OF LIGHT AND SHADOW

Symphonic Staircases of Light and Shadow

Light, both natural and artificial, is a fundamental element in architecture that goes beyond its function of illumination; its importance lies in its ability to define and create space, transforming the perception and experience of a space. Additionally, it has the capacity to adapt to the specific needs sought by each architectural project, providing beauty, character, and functionality to spaces. Beyond its practical purpose, lighting is a crucial element in the perception of a building; light has the ability to highlight forms, shape objects, and create consecrating and welcoming environments.

Light works in conjunction with shadow; they are not opposing elements but two complementary ones that interrelate and mutually define each other. Junichiro Tanizaki, a Japanese writer, in his essay ”In Praise of Shadows,” defines light as representing clarity, transparency, and superficiality. Conversely, he defines shadow as depth, mystery, and subtlety. In Japanese architecture, light filters and is modulated through elements like shoji screens and inner gardens, creating intimate and evocative spaces. Tanizaki believes that beauty resides in the harmony between these two elements. An architecture that seeks only light is cold and dehumanized, while one that seeks only shadow is dark and oppressive.

That said, as has been observed in many parts of the world, architecture often develops without considering natural light on sloped terrain, leading people to excessively use artificial lighting and resulting in a loss of connection to the surrounding natural environment. Moreover, when working on sloped terrain, we tend to intervene drastically. The use of natural light can be a source of renewable and sustainable energy and can help reduce energy consumption. Bearing this in mind, our project, which is a two-family dwelling, makes good use of natural light during the day, thus minimizing the use of artificial lighting. Additionally, we thought carefully about how to intervene in the terrain without altering it entirely.

Through this approach, the location chosen for the project is in the foundational center of Usme, Plaza de la Alcaldía, in Bogotá, Colombia. This area is both rural and urban, where we have a close view of housing complexes and, in the distant view, part of the Bogotá cityscape. It is situated on sloped terrain, and by using terraced architecture, we make good use of large windows that allow for these views and maximize natural light.

We use natural light to achieve maximum energy efficiency through large windows with lattices to recall the locality’s history and with gabled roofs with windows to facilitate light entry. Thus, we optimize and take advantage of the natural light available in our environment daily.

The history of the locality dates back to the appearance of settlements of the indigenous culture, especially the Muisca. In Muisca culture, light had a transcendental significance. For the Muisca, sunlight not only represented the source of life and vital energy but was also intrinsically linked to their spiritual beliefs and rituals. They considered the sun a deity, worshiping it in their ceremonies and festivities. Sunlight guided their daily activities and marked the rhythm of their lives, from planting to harvesting, establishing a profound connection with nature and the life cycle. We incorporate architectural elements that capture and filter natural light similarly to how the Muisca did in their ancestral constructions. Additionally, we use lattices on the stairs, which cast shadows of Muisca symbols during daylight, so users, as they ascend the stairs, remember their history and identity, thus establishing a relationship between humans and their environment. This not only provides adequate and sustainable lighting to our interior spaces but also creates a unique sensory experience, where light plays a fundamental role in the perception of the environment and the connection with local history and culture.
In conclusion, the integration of light and shadow in architectural design transcends mere functionality, serving as a bridge between the past and present, nature and human-made environments. By thoughtfully incorporating natural light and considering the historical and cultural context of the Muisca people, our project not only achieves sustainability and energy efficiency but also fosters a deeper connection between inhabitants and their surroundings. The symphony of light and shadow in our two-family dwelling not only enhances the aesthetic and practical aspects of the space but also evokes a sense of identity and continuity, honoring the rich heritage of the locality. Through this harmonious blend, we create spaces that are not only visually captivating but also deeply rooted in cultural significance and environmental consciousness, demonstrating that architecture can be both a tribute to history and a path to a sustainable future.
