Carrot Holdings Headquarters Building

Carrot Company, founded in Osaka in 1988, has long been engaged in the planning, manufacturing, and sales of bags and umbrellas. The new headquarters was envisioned as an architectural expression of the company’s philosophy: not to follow short-lived trends, but to create enduring essentials that remain cherished over time. The building is a steel structure with eight stories above ground, a total floor area of 4,150 square meters, and a maximum height of 35 meters, establishing a strong presence in the city.
The design pursues timeless value through the principle of the Golden Ratio (1:1.618). The facade is composed with strict proportional order, achieving an elegant, balanced, and enduring presence. Light-colored granite, resonating with the corporate identity, symbolizes growth and continuity. The Golden Ratio extends beyond the exterior, applied to the rhythm of interior joints and signage, creating coherence and a calm spatial rhythm. This integration allows the architecture itself to communicate enduring value to the urban landscape.
Inside, a double-height stair links the showroom and offices on the first and second floors, encouraging integration among departments and fostering innovation. The rooftop garden and wooden deck provide places of rest, inspiration, and communication, enhancing daily use while also connecting the building to the wider urban life.
Architectural details reinforce the identity: granite mullions layered to emphasize verticality, a facade composition structured on the Golden Ratio, and a podium distinguished with depth and shadow. At night, lines of light from the landscape highlight the granite facade, offering a grandeur distinct from its daytime dignity.
Through geometric order and material precision, the project transforms corporate philosophy into architectural form, presenting the image of a “timeless enterprise” within the urban context.
