Firefly: Housing, Infrastructure, and Public Space in Almada | Architecture Thesis

Site Context

From a geological perspective, the terrain is composed mainly of clay, sand, limestone, and sandstone formations. Due to these unstable ground conditions, the proposed intervention takes the form of a steel structure that touches the surface at only two points, functioning as an inclined bridge. Due to these unstable ground conditions, the proposed intervention takes the form of a steel structure that touches the surface at only two points, functioning as an inclined bridge.

Design Process

In the beginning, the main concern was how to anchor the structure safely on a geologically fragile hillside. The initial idea considered using many pillars to distribute the loads over several points and reduce the impact on the ground. However, after weeks of research, studying geological reports, and reviewing core samples from the area, it was realized that the most reliable approach was to limit ground contact as much as possible. This led me to the idea of making only two strong anchors, fixed directly into the hardest layer of limestone.

After consulting with several engineers, the concept evolved into the use of a steel truss, similar to the structure of a bridge. This solution provides high mechanical strength while minimizing pressure on the terrain. On top of the truss, it was planned to place lightweight housing units, built from recycled and sustainable materials such as wood and sheet metal. This approach combines structural stability with environmental sensitivity, reducing the footprint on the landscape while creating functional and resilient living spaces.

Final Outcome

The project aims to add a silent yet significant presence to a forgotten area, much like fireflies—nearly invisible insects that expose themselves for a brief time, luminous and fleeting, moving through the dark. The project, which is being proposed as a prototype, will adapt to the site’s steep and uneven topography, adjusting to the many slopes along the terrain without compromising its delicate balance.

The project combines public and private functions in a hybrid structure. Through stairways and slanted elevators, it creates a new connection between the riverfront and the raised town of Almada, incorporating amenities like cafes, bathrooms, bike rentals, and communal gardens with nearby markets. Families or students can live in the private, modular residential levels. From an environmental perspective, the building aims for self-sufficiency, for instance through rainwater collection. 

This design not only enables a new form of vertical connectivity but also incorporates residential and service spaces, contributing to the regeneration of the area. The housing units, positioned above the steel truss, are made of prefabricated timber elements and are accessed via stairways and elevators integrated into the supporting system.

Conclusion: Ultimately, the project acts as an urban activator, fostering community by merging infrastructure, housing, and public space.
