The project entails an innovative building that integrates the functionalities of a spa and a
diving center. This facility is designed to accommodate individuals of all age groups, offering
opportunities for relaxation and sports activities. Its uniqueness lies in the inclusion of a pool
with a lowered bottom and a deep pool with a depth of 25 meters, catering to a diverse
range of users, including diving enthusiasts.
Moreover, the entire building is constructed from an ecological material known as mycelium,
representing a breakthrough in sustainable construction. Mycelium, a network of fungal
hyphae, is not only durable and weather-resistant but also biodegradable and
environmentally friendly.
As a result, this project represents an ideal fusion of functionality, innovation, and ecology.
It provides an excellent setting for individuals seeking relaxation and sports activities while
prioritizing the natural environment. Through the use of ecological solutions, the facility
minimizes its impact on the environment while upholding a high standard of service. In this
manner, the project successfully harmonizes various aspects such as ecology and
sustainable development, creating a space that is both functional and environmentally
friendly.

The design of the building is inspired by barnacles, small crustaceans that feed on plankton. These
sessile animals have a body protected by a shell made of calcite plates. At the top of the shell is
an opening through which the barnacle extends its feeding appendages. These fascinating
creatures can be found in the sea, attached to shells, stones, rocks, or pieces of wood. The idea behind the project was to create a place where diving would be possible throughout the
year, regardless of the weather. Bivalvia offers the opportunity to dive at every level of progression,
from beginners to professionals. Additionally, for those who do not want to participate in diving,
we have provided multilevel recreational pools, which in shape and arrangement imitate a coral
reef, as well as a spa. Furthermore, Bivalvia gives us the opportunity to admire divers in the
deepest pool, both from the building’s lobby and from a small restaurant.

The entire building is integrated with nature, with panels made from mycelium - the network of thin
threads that form the body of a fungus. Mycelium is extremely important for the ecosystem as it
aids in the decomposition of organic matter and the circulation of nutrients in the soil. The use of
mycelium in the construction of Bivalvia is a testament to the commitment of the project to
sustainability. Mycelium panels are used for thermal insulation and soundproofing, due to their
unique properties, such as self-regeneration ability, biodegradability, fire resistance, and cost-
effectiveness.14 15 Moreover, the facade of the building and the roof are covered with a cladding
made from this fungus. Over time, the mycelium will become an ideal place for lichens or other
plants, further integrating the building with its natural surroundings. The unique shape of the building, inspired by the shape of the barnacle, allows efficient use of space, accommodating various facilities and services within the center. The design serves as a
symbolic connection between the aquatic center and the marine world it represents, standing as
a testament to the center’s commitment to providing an authentic and immersive diving
experience.
The Bivalvia initiative in Gdańsk is a remarkable endeavor that underscores the city's unwavering
commitment to trailblazing technology, environmental sustainability, and the promotion of diving as both a recreational and professional activity. This ambitious project aims not only to construct
a state-of-the-art diving centre that caters to the needs of divers of all levels but also to revitalise
the city's surroundings and bolstering the regional economy. The initiative is a testament to
Gdańsk's innovative spirit and forward-thinking vision, and it has the potential to bring about a
positive change not only for the diving community but also for the city and its inhabitants.
The Bivalvia project is expected to attract divers from all over the world, boosting tourism in
Gdańsk. The center will offer a variety of diving experiences, catering to divers of all levels. The
multi-level recreational pools, designed to mimic a coral reef, will provide a unique and immersive
experience for visitors. The spa facilities will offer relaxation and wellness services, improving the
overall visitor experience.
