Context of the Location of the Building
On the outskirts of the center of Kaunas, along Raudondvario Avenue, there is a rather chaotically developed old industrial area that lacks a clear urban structure. However, it stands out with a unique advantage—its location by the Nemunas River, next to its picturesque valley. This inspired the international company "Sanitex" to implement its bold vision of working in nature here. Their new office is not just an administrative building but a green oasis, created in the midst of a chaotic environment surrounded by asphalt and concrete.

Architectural Concept of the Building
The Sanitex administrative building is an office in the forest. The owner of the Sanitex company, unlike many other clients, did not want a multi-story building that would stand out from its surroundings, but rather a modest office that blends with nature.
The main idea of the "Sanitex" office was to plant a forest in the existing barren industrial area and create a building that would not overshadow the environment, integrating as much as possible into the lush surroundings and turning into a workspace in the forest.
The low office building hides within the greenery and achieves the desired effect—employees do not see the industrial area. Looking through the large windows of the façade, they feel like they are working in nature. Even on the second floor, employees are surrounded by nature: in the distance, the river valleys are lush, below, a newly planted forest rustles, newly installed fountains trickle, and a flowing stream has been created, while the roof is covered with moss, vines, shrubs, pines, and birches.

Key Design Decisions and Materials
The nearly 9,500 m² building located along the Nemunas River consists of two floors, with a closed inner courtyard, a green roof, and an underground parking lot. The restrained glass and aluminum façades of the building exude minimalism, making the lush environment the main focal point.
On the first floor of the building, workspaces dominate, while the second floor houses the director’s office, meeting rooms, a large green space for employee recreation, and a cafeteria with an outdoor terrace on the roof. The entire first floor's work areas, including small kitchenettes, printing spaces, restrooms, and various meeting rooms, can be accessed in a loop. This layout not only facilitates movement within the office and sharing of all auxiliary functions but also allows for easy restructuring of workspaces, adjusting the sizes and locations of office departments as needs change.
At the client’s request, the interior, like the exterior, was designed to not overshadow the greenery, being neutral like the walls of a gallery that do not compete with paintings, or becoming a backdrop that highlights the plant life. The office is dominated by open concrete and transparent glass partitions, which are combined with natural and painted wooden furniture and ceiling elements, with some touches of "Sanitex" red, perforated metal inserts, and extremely soft carpeted acoustic flooring. Efforts were made to minimize decoration inside the building, with finishes being added only as accents, and most of the space being defined by the structural elements.
As in the outdoors, the key feature inside the building is the plant life—most of it is integrated into custom-designed furniture. Special supporting structures were built for vines, and plant-filled shelves were used to divide spaces. A striking vine, over six meters tall and spanning two floors, has been planted next to the main staircase. Large mirrors, reflecting the plants, have been hung in several places to enhance the effect.
In winter, when some of the trees outside shed their leaves, the greenery inside becomes more prominent, while in summer, it merges with the outdoor greenery. No matter which direction employees move, they are always accompanied by the forest outside the window and greenery inside.
Indoor plants not only contribute aesthetically but also improve the office's acoustic comfort.
The office lighting is also restrained—there is a lot of hidden lighting inside, with uniform metal pendant lights and ceiling-mounted lamps. The focus was not on the design of the fixtures but on their quality and functionality—an advanced lighting system, oriented to human biorhythms, has been installed, mimicking the spectrum of sunlight.
