Oasis Under a Building by fala – Innovative Glass House in Porto, Portugal

A Conceptual Reversal: The Glass House Inverted

The Oasis Under a Building project by Portuguese architecture studio fala challenges conventional domestic design with a radical approach: a glass house turned inside out. The architects describe it as “like a sock with a hole,” where divisive transparency is redirected inward, and loose objects hover at the periphery. The result is a conceptual home that reinterprets openness and privacy, offering an intimate yet visually permeable environment beneath a larger structure.

Spatial Innovation: Fluidity and Continuity

Spanning 1,292 square feet, the house is organized as a single, continuous space that can be read as multiple interconnected areas. Rather than conventional compartmentalization, the design emphasizes fluidity, allowing the interior to breathe and the eye to wander. Ornamentation and subtle structural interventions suspend key elements, while the ceiling functions as a bright sky, creating a sense of levitation and lightness.

Materiality: Concrete, Glass, and Transparency

Materials play a central role in defining the character of this home. Concrete surfaces provide grounding and structural clarity, while expansive glass panels foster a dialogue between interior and exterior, maintaining visual openness even under a larger building envelope. Bathrooms and intimate spaces are integrated seamlessly, their transparency curated to balance intimacy with light.

Architectural Storytelling: A House Between Boundaries

The Oasis Under a Building is more than a home—it’s a spatial narrative. By inverting traditional concepts of domesticity, fala encourages residents to experience architecture in an unconventional, poetic manner. Loose objects, suspended elements, and reflective surfaces create a dynamic environment, where each moment in the home unfolds differently depending on perspective and light.

Plan and Collage: Structuring the Invisible

The architectural plan is minimal yet sophisticated, using collage-like layering to define zones without rigid walls. This approach enhances the sense of openness and allows natural light to penetrate deeply, activating concrete and glass surfaces throughout the interior.

Photography and Documentation

Photography by Francisco Ascensão, Lera Samovich, and Giulietta Margot captures the ethereal quality of the space, highlighting the interplay of light, material, and suspended elements. The images communicate the home’s conceptual depth, emphasizing transparency, structural subtlety, and the poetic inversion of traditional domestic spaces.
