Balancing these aspects required prioritizing project goals in line with the client's values. Objective 1: Sustainable Materials Preserving existing materials is the core of sustainable design. With the complete change in function of 2 floors, only 27% of walls were demolished, and new walls reduced by 5%. Almost 95% of original floors, including wooden parquet, were retained. Bathroom fixtures and tiles were cleaned and repaired, with only irreparable elements replaced with water saving alternatives.

The project championed a "selective redesign" approach, introducing local handmade mosaic floors and recyclable carpeting in conference rooms. Objective 2: Lighting and Acoustics Effective lighting and acoustics are crucial for good working conditions. Daylight-sensitive linear fixtures were installed in all offices, reducing energy consumption and supporting circadian rhythms. An acoustic analysis of common spaces was conducted, which guided the selection of materials and panels for ceilings and walls.

Acoustic booths were introduced in corridors. Objective 3: Polish Design Promoting Polish design and honoring furniture-making traditions, 98% of furniture is from local manufacturers, which considerably shortened supply chains and reduced carbon footprints. Objective 4: Modern Interiors Striking a balance between historical architecture and a homely atmosphere, social areas feature vibrant colors, while offices prioritize architecture, allowing tenant personalization.
