The paper deals with the digital architecture concept which is trying to introduce a new spatial language into the con-text of water urbanism, using nature as a model, measure and mentor. The first part analyses Biomimetics with its design strategies and methods. The Problem-Based Approach (designers look to nature for solutions) and the Solution-Based Ap-proach (biological knowledge influences human design) are defined here. In the second part of the research, the authors present selected examples to the topic. This case study has demonstrated that a new approach to architectural design is emerging. This approach redefines the process of architectural design, understood not as the traditional shaping of the ob-ject's form, but as a compilation of various factors resulting from changeable climate characteristics and ecology. The con-clusions emphasize that not only the contemporary understanding of ecology should be changed, but also the way architects approach the built environment, especially in the aquatic environment.
