CAS Studio

CAS (collective for sustainable architecture) is a multidisciplinary studio founded by architects Alina Jerónimo and Paulo Carneiro, that follows a working strategy towards sustainability: a balance of social, cultural, environmental and economic factors in the design process.

Our vision:

Is to improve the well-being of people and communities, creating healthier buildings and cities in balance with natural environment.

Our mission:

Is to design and build with environmentally friendly materials recovering and improving ancient craft-works and technologies, adapting them to our time comfort requirements and relating people and environment in an integral system.

We are:

– Searching continuously for new ways of connecting humans with natural environment through matter and space, art and science: architecture.
– Developing sustainable technologies with natural/bio-based materials in partnership with universities.
– Designing from the small screw to the city scale in an integral system that connects every element in a living organism.
– Rehabilitating historical buildings with ecological technologies upgrading ancient knowledge to contemporary comfort demanding.
– Imagining new buildings that can contribute to a new construction paradigm shift.
– Building utilitarian objects made of natural and non toxic, low carbon footprint materials.
– Using workshops, expositions and lectures to reach new people with the same interests.
