CLIFFSCRAPER: A Sustainable Skyscraper Design Rooted in Topography

Is it possible to build a skyscraper without constructing a new structure? Can topography itself transform into a vertical living space? These provocative questions lie at the heart of Cliffscraper, a groundbreaking project that reimagines what a sustainable skyscraper design can be.

In today’s urban landscape, most high-rises are constructed using materials like steel and concrete—resources that significantly contribute to environmental degradation. As the demand for urban housing increases, these construction practices have become synonymous with a growing carbon footprint. In response, Cliffscraper offers an alternative—one where the structure is carved from the earth itself, reducing emissions and embracing the natural terrain.

Using Santorini’s Landscape as Structure

The project is based on the island of Santorini, Greece—a place defined by volcanic cliffs and centuries-old vernacular architecture. After a volcanic eruption in 1600 BC reshaped the island, steep calderas and rugged topographies emerged. Locals adapted by carving cave homes into the cliffs, forming a sustainable and earthquake-resistant way of living. Cliffscraper adopts this tradition, transforming the cliffs into vertical life lands while preserving the silhouette of the island.

Topography as Architecture

Instead of constructing a new high-rise, Cliffscraper integrates the cliff into the architectural design. By following the natural slit in the rock, spaces are carved—never added. This process respects the geological integrity of the site while minimizing visual impact. Removed soil is reused within the project site, reducing the need for external materials. The result is a sustainable skyscraper design that emerges from its context rather than disrupting it.

Addressing Overtourism and Urban Pressure

Santorini, despite its size, suffers from overtourism. The surge in seasonal visitors puts enormous pressure on its infrastructure, land, and water resources. Farmlands are vanishing as new accommodations rise. Cliffscraper proposes to consolidate future vertical development within the cliff itself—preserving horizontal land for agriculture and mitigating urban sprawl.

Wave Energy and Fresh Water Solutions

Positioned at the edge of the sea, Cliffscraper leverages its location to develop renewable wave energy. This form of energy is predictable and efficient—unlike solar or wind—and can desalinate seawater while producing power. The structure aims to meet its own energy needs and potentially provide surplus energy and fresh water to the island, boosting both sustainability and economic resilience.

Equity in Tourism and Agriculture

The economic disparity between tourism and agriculture has pushed locals to abandon their traditional livelihoods. With Cliffscraper, wave energy-generated fresh water can support irrigation, revitalizing agriculture and creating economic balance. This new infrastructure aspires to benefit both locals and tourists, offering accessible public spaces and cultural programming within the carved spaces.

Integrated Vertical Mobility and Access

Cliffscraper is accessible from both sea and land. Visitors can arrive by boat or descend via internal circulation systems from the top. Unlike the existing donkey-led zigzag roads, the vertical core offers efficient movement between levels while activating the carved interior with public spaces, museums, and accommodations.

A New Model for Sustainable Skyscraper Design

Designed by Meltem Yılmaz and Aylin Yıldırım, Cliffscraper isn’t just a concept—it’s a call to rethink architecture. It exemplifies a sustainable skyscraper design that respects nature, utilizes existing topography, and eliminates the need for high-emission materials. In doing so, it doesn’t just blend into the land—it becomes a part of it.

This project shows how architecture can coexist with environmental systems while offering innovative solutions to urban density, energy, water scarcity, and cultural preservation—all through the lens of terrain-based vertical design.
