Living the Baltic through architecture

Located in Wiślinka, Poland, on the Baltic coast and at the mouth of the Vistula River, Sol Marina is an exclusive residential development conceived around a unique relationship with the waterfront. The project brings together luxury villas and apartment buildings in a setting where every residence enjoys direct access to private marinas, creating a distinctive living experience rooted in calm, privacy, and proximity to nature.

Designed by architect Marcin Karczewski at K&M Design, and built by Dekpol, Sol Marina reflects a contemporary interpretation of waterfront architecture. Its design responds to the expectations of a residential enclave shaped by exclusivity, openness, and a strong connection to the sea. The project is also promoted by renowned Polish sailor Mateusz Kusznierewicz, reinforcing its maritime spirit.

For phases II and III of the development, Neolith Just White was specified for the facades of the apartment buildings, covering a total of 15,000 square meters. The material was selected as a response to both the visual direction of the project and the technical demands of its location.

Its location beside the marina placed clear demands on the building envelope, calling for a material able to combine visual refinement with reliable long-term performance in an exposed waterfront setting.

“We were looking for a material that would be both highly durable and visually elegant. The development is located directly next to a marina and within a coastal environment, where materials must withstand humidity, wind, and changing weather conditions. Neolith allowed us to achieve the right balance between high technical performance and a calm, timeless aesthetic.”

The design of Sol Marina draws directly from its surroundings. Rather than competing with the scenery, the architecture was conceived to feel naturally connected to the marina and the broader waterfront environment. The result is a calm and carefully balanced composition that feels at home in the coastal landscape.

Within this approach, the use of large-format Neolith surfaces helped create broad, clean planes across the facades, strengthening the project’s overall sense of order. The Just White model brings brightness and clarity to the buildings, while supporting a design vision influenced by Scandinavian simplicity and contemporary waterfront architecture.

“Thanks to its large-format manufacturing, Neolith allowed us to create clean, elegant surfaces while minimizing the visibility of joints. At Sol Marina, our goal was to achieve a minimalist, harmonious architecture inspired by the water and the coastal landscape, and this material aligned perfectly with that aesthetic.”

Sol Marina combines wood, glass, and metal in a composition shaped to reflect the calm, contemporary character of its waterfront setting. Within that palette, Neolith helps connect these materials through a refined and understated surface expression.

Its neutral appearance supports cohesion across the facades without overpowering the other architectural elements, while its understated finish contributes to the project’s overall sense of visual balance.

“Sol Marina is based on the combination of several key materials: wood, glass, metal, and mineral surfaces. Neolith acts as a neutral yet elegant element that ties these materials together and highlights the contemporary character of the architecture.”

One of the most distinctive features of Sol Marina was the bespoke production strategy developed specifically for the project. Because of the size of the development and the design requirements of the villas and apartment buildings, Neolith studied the facade layout in detail and adapted production to improve slab optimization.

Across three phases delivered over three years, production was adapted to create custom slabs in special formats tailored to the needs of the project. This custom approach made it possible to align the material more precisely with the architectural design, maximizing slab use and significantly reducing waste. It also improved cost efficiency for the client, all without additional cost to the project.

This level of adaptation added both practical and environmental value, showing how technical flexibility can support ambitious architectural schemes while improving material efficiency.

For Sol Marina, performance over time was closely linked to a more thoughtful approach to material selection. Durability, low maintenance, and lifecycle value all played an important role in meeting the needs of a large-scale residential development while supporting a more responsible design strategy.

“Contemporary architecture increasingly relies on conscious material selection. In projects such as Sol Marina, it is important not only how the building looks, but also how it performs over time. Materials with high durability and a long life cycle, such as Neolith, are a natural part of responsible design.”

“In a coastal environment, material durability is crucial. Neolith is resistant to moisture, UV radiation, and everyday wear, which allows the surfaces to maintain their visual quality for many years while requiring minimal maintenance.”

Architect

Sol Marina shows how residential architecture can respond to a privileged location through measured design decisions, durable materials, and a strong sense of cohesion. Its connection to the marina, its refined palette, and its tailored facade solution all contribute to a development designed for long-term appeal.

Through a combination of custom production, large-format cladding, and a material chosen for both performance and visual restraint, Neolith contributes to a project that reflects a refined vision of contemporary coastal living.
