Why Cape Verde

A territory between
memory and future.

At the crossroads of Africa, Europe and the Atlantic, Cape Verde is far more than an archipelago. It is a territory shaped by encounters, migrations and cultural exchanges that have left deep traces in the landscape, the cities and the people, creating a layered identity where memory and transformation constantly coexist.

The ARCH CHALLENGE architecture competition draws its inspiration from this unique setting — a place where bold ideas for the future can take root in a rich, living history.

Today, facing the challenges of our time, climate, resources, growth and identity, Cape Verde stands as a unique laboratory for imagining new ways of living and building, rooted in context and open to the future.

For ARCH CHALLENGE, this territory becomes a field of architectural research, where real places, real constraints and real opportunities can generate ideas capable of connecting local culture with a broader contemporary vision.

01Atlantic Identity

An archipelago shaped by the ocean, a meeting point of cultures, exchanges and perspectives.

02Landscape & Memory

Volcanic landscapes, exposed coastlines, arid valleys. The memory of a territory built through migration, adaptation and resilience.

03Contemporary Architecture

An authentic and evolving context, where architecture can generate value through culture, climate and community.

AI & Architecture

AI Is A Tool.Not The Project.

Artificial intelligence may be used as part of the design process, supporting research, representation, scenario building and the exploration of architectural possibilities.

Its role is not to replace critical thinking, cultural awareness or spatial intelligence. The value of each proposal remains tied to the authors' ability to transform tools, ideas and context into a coherent architectural vision.
