In Sopot, Poland, about 400 meters from the Baltic Sea, the Warsaw-based architecture agency FAAB completed the Wave 4 and Wave 5 buildings of the ECR medical complex for Grupa Invicta Sp. z o.o. in 2026. These two structures cover a total area of 4,744 square meters, with Wave 4 measuring 2,957 square meters and Wave 5 measuring 1,787 square meters. The budget for the project was not disclosed in the press release. The ECR medical complex is a multi-phase development that includes a laboratory for medical analyses (Wave 1), an outpatient clinic and ambulatory surgery hospital (Wave 2), a specialized hospital (Wave 3), and pre- and post-intervention care facilities (Wave 4 and Wave 5). Wave 4 and Wave 5 feature supervised medical accommodation rooms, a restaurant, and a large rehabilitation center offering movement therapy and advanced treatments such as laser therapy, cryotherapy, and hyperbaric oxygen therapy, which is known to speed up post-surgical healing. The design of the buildings was inspired by the photographic series AquaViva by Pierre Carreau, which captures marine landscapes. The wave-like geometry is most visible in the upper sections and sculptural entrances of the buildings. Sunlight reflecting off the façade emphasizes its detailed divisions, creating a dynamic, three-dimensional appearance. The perforated aluminum panels on the façade replicate the "Flower of Life," a sacred geometric pattern traditionally linked to healing and found in ancient Egyptian temples, Indian architecture, and Mayan artifacts. This design choice echoes local traditions of using decorative motifs on building façades. The pattern spans the entire façade, including flat sections, sections with varying shapes, and shutters, with the perforation continuing seamlessly across panels for a unified visual effect. The buildings have two distinct sides tailored to the needs of their users. A white exterior envelope helps reflect sunlight and protects the south, east, and west walls from excessive heat. The window shutters can form a continuous protective barrier when needed. The balance between open sections and solid parts of the panels was refined using 1:1 scale physical models. This design allows the building to remain comfortable even when all shutters are closed, reducing the need for air conditioning in the summer. Prefabricated balconies add a rhythmic play of light and shadow on the façade, while the balcony railings help conceal private areas from view. Inside, the spaces are designed to promote a sense of security and relaxation, especially before and after medical procedures. Medical technologies, such as nurse call systems, are discreetly integrated into the décor. A seaside garden, visible from windows, balconies, and ground level, offers a therapeutic environment, even for patients confined to their beds. The garden, composed of native dune plants, lies between the buildings and contributes to the area's healing atmosphere. 3D modeling was crucial in both the design and construction phases, with separate digital models developed for the building's exterior, metal framework, and concrete structure. These techniques helped optimize material use and speed up construction. The project was built on a former industrial site that had long been in disrepair, transforming 5 hectares of land into interconnected green spaces and parks. Rainwater harvesting systems installed on the site significantly reduce the burden on the local stormwater network, contributing to sustainable urban development.
