For the Solaris project in Mersin, Lungo Fucile was responsible for the interior design of the 4+1 and 5+1 apartment types, working within the existing architectural project. The two residential typologies, each with different sizes and spatial programs, were developed in response to the existing plan organization, user needs, and patterns of everyday life, creating a cohesive interior identity throughout the project.

In addition to shared living spaces such as the living room, dining area, kitchen, and entrance hall, the bedrooms, master suites, dressing areas, and bathrooms were designed as part of an integrated whole through coordinated decisions on materials, colors, furniture, and lighting. Curved transitions, custom-made built-in furniture, mirrored surfaces, textiles, and timber textures define the character of the project, while the varying material and color choices across different spaces are balanced within a consistent overall design language.
