The penthouse is an extension of an existing building in the center of Athens, one of the most notable examples of modernist housing from the 1930s and possibly an early precursor to Brutalism. Restoring the building and adding an extension presented a complex challenge, not only from an architectural and construction perspective but also in terms of its cultural and social significance.
The primary design objective was to strike a balance between a functional and an archaeological approach, respecting both the architect’s original vision and the contemporary socio-political context of Athens. This led to the decision to preserve many of the building’s original elements while simultaneously redesigning the interior to create flexible spaces that accommodate modern living needs.
The extension was conceived as a structural radiograph of the building—an abstract projection that reveals hidden relationships within its geometry. By allowing all columns to extend upward, the design exposes both the discontinuities and the inherent freedoms within the otherwise rigorous architectural principles of Siagas, the building’s original architect from the 1930s. This exoskeleton, reminiscent of a deconstructed frame, deliberately rejects ornamentation, instead emphasising structural expression while maintaining a profound connection to the modern essence of the original structure. Rather than disrupting the architectural language, it enhances the spatial experience, framing the transition from design to realisation.
The preserved front facade, clad in artificial plaster, was carefully restored with targeted interventions where necessary. To enhance energy efficiency, the extension and rear facade were constructed with thermal insulation, deliberately distinguishing the new additions from the historic frontage.
