Waterfront Terraces – Amphitheatric Roofscape on the Chalkida Waterfront, Greece

Waterfront Terraces proposes an inhabitable amphitheatric roofscape that redefines the threshold between city and water in Chalkida, Greece. Located at the coastal square marking the urban edge, the project establishes spatial continuity between the built fabric and the maritime horizon while preserving unobstructed views toward the waterfront. The intervention is conceived as a hybrid between architecture, landscape, and civic infrastructure, allowing the roof to operate as an accessible public ground while cultural functions are embedded beneath the terrain.

Rising gradually from the existing public surface, the stepped composition aligns with the surrounding urban fabric and transforms the building into an elevated civic platform for gathering, pause, and collective observation. The roofscape unfolds through a sequence of terraces that frame views toward the city and the dynamic coastal environment, creating a shared spatial horizon where visitors engage with the waterfront from multiple elevations. Inspired by the collective spatial experience of ancient Greek theatres, the design translates amphitheatric geometry into a contemporary public landscape that encourages movement, gathering, and visual continuity.

Materially, marble surfaces anchor the project within local construction traditions while reinforcing the continuity of the urban ground. During nighttime, discreet linear lighting traces the geometry of the stepped form, allowing the roofscape to appear as a subtle yet recognizable presence along the waterfront.

Beneath the elevated public platform, cultural spaces are organized as protected volumes embedded within the terrain. The main exhibition hall unfolds in visual dialogue with the coastal edge, where large framed openings establish moments of continuity between interior and exterior, allowing visitors to perceive the movement, light, and atmosphere of the water from within the interior landscape. Sectional height differences support passive environmental performance, enabling natural ventilation to flow from the lower cultural spaces toward the elevated roof, contributing to passive cooling and reduced mechanical demand.

The project is an unbuilt preliminary architectural study developed in 2025 in Chalkida, Euboea, Greece, by Varvara Christopoulou Architecture (Athens, Greece).
