How it works

Straight answers on building on water, investing and the container approach.

Why build on water?

Building on water, rather than solely on land, presents increasingly relevant advantages in the face of accelerating climate change. Rising sea levels, wall cracks due to drought, earthquakes and increased frequency of flooding pose significant threats to traditional land-based infrastructure. Floating or elevated water-based structures offer inherent resilience to these challenges, adapting to fluctuating water levels without the catastrophic damage incurred by fixed land structures. Furthermore, these platforms can be designed to integrate sustainable technologies, such as wave energy capture and water purification systems, transforming potential hazards into valuable resources.

Why invest and live in a water house in Europe or Asia?

Europe or Asia offers a compelling blend of opportunities for investment, building, and living. Its burgeoning economy, particularly in sectors like technology and tourism, presents attractive investment prospects and potential for business growth. Building here can be cost-effective compared to other Western European nations, with a variety of landscapes and architectural styles to choose from. Most importantly, Portugal boasts a high quality of life characterized by a warm climate, stunning beaches, rich culture and history, delicious cuisine, and a welcoming and safe environment. The relatively low cost of living, coupled with excellent healthcare and education systems, makes it an ideal place to establish roots and enjoy a fulfilling retirement lifestyle.

Why engineered with shipping containers?

The rise of floating architecture is a testament to human innovation in the face of limited terrestrial space and shifting sea levels. While traditional houseboat construction often relies on wood frames and custom pontoons, the use of retired ISO shipping containers presents a highly compelling and practical alternative for building a house on water. These robust units, originally engineered to endure the rigorous conditions of ocean transport, offer a blend of inherent durability, structural integrity, and sustainable cost-effectiveness that makes them an ideal module for aquatic habitation.
