Set within a lush, green environment, this office relocation project leverages expansive windows to integrate natural light into the workspace. The design facilitates a flexible environment where staff can choose their setting based on the day’s tasks or their personal mindset. While the main work areas utilize a beige-based palette to harmonize with existing furniture and foster a sense of calm, the meeting and open spaces transition to gray tones, creating a focused atmosphere with a productive sense of clarity. The strategic placement of the company’s art collection further enhances the interior, adding visual depth and clear sightlines throughout. By meticulously balancing material textures and lighting, the office achieves a cohesive, natural environment that feels both professional and inviting.

This is an office relocation project for CHERRY Inc., a company engaged in addressing social issues through a wide range of creative planning and production, primarily in the advertising field. In the entrance hall, a custom-made counter made of Bealstone infused with the company’s signature logo color glass serves as a multifunctional space—for meetings, workshops, and as a community hub for both internal and external creatives. On the second floor, custom-built desks with integrated partitions were installed to help each individual stay focused. The overall layout encourages circulation, creating a compact yet well-balanced sense of distance between individuals and teams. The space is also designed to display CHERRY’s diverse collection of artworks—accumulated since the company’s founding—throughout the office.

This is an office relocation project for Katariba, a certified nonprofit organization committed to creating a society where all young people—regardless of their upbringing—can nurture the creativity and motivation to shape their own futures. In a post-pandemic work environment, with around 80% of staff working remotely, the project was developed in close collaboration with the client to explore the purpose and value of gathering in a shared space. In response to the client’s desire to “create spaces that foster dialogue,” the design centers on the concept of the engawa—a traditional Japanese architectural element that blurs the boundary between inside and outside. Engawa-like features were incorporated on each floor to encourage casual, spontaneous interaction, such as placing benches face-to-face or installing high counters along circulation paths. The overall space is unified in soft gray tones, accented by “Katariba Green,” the organization’s signature color, to create a warm and approachable atmosphere. Signage was designed by YOHAK DESIGN STUDIO, and sound design was handled by Sound Couture Inc., resulting in a spatial experience that engages both sight and sound. The conversations and connections that emerge here will continue to deepen the value of the space over time.

This is an office relocation project for Khaki Co., Ltd., a VFX direction and design company. In addition to an office and meeting room, a preview room was required to check the produced images. The conference room and preview room, which frequently receive visitors from the outside, were placed in an entrance area separated from the office to ensure security of the office. The office area is large enough to accommodate future increases in staff, and includes a lounge for employees. The lounge will be used not only for breaks but also for dinner parties, so we designed sofas and side tables that can be reconfigured to suit the needs of the client.

This is an office relocation project for Commons Asset Management, an investment management company. The new location is on the top floor of a high-rise building overlooking the natural beauty of Meiji Jingu Gaien, and the office was planned based on the keyword “Nature” through dialogues with the client. In addition to office space and meeting rooms, a lounge space for workshops and lectures and book storage space was required. The space was partitioned with fixed bookshelves and movable furniture to accommodate a variety of layouts. By using the keyword as a clue to determine materials and details, we hope that each part of the office space will have a common context and become a new “common ground,” which is the origin of the company name, as people gather there.

This is the Tokyo office of SNARK Inc. The office and material room were planned to fit the existing floor plan where the plumbing is concentrated in the center of the space. We designed three types of desks for the office room: freestanding, wall-supported, and shelf-supported, depending on where they are placed. We also designed slits into the desk tops to store charging cables, pens, and tissues. Products such as shelves, lighting, and paper holders were designed to be attached to the existing wall surface to create a sense of unity. To facilitate DIY installation of shelves in the material room, we designed stacked shelves with ready-made size tile tops and mirror-surfaced SUS pipes. This is an office of designers, by designers, for designers, where new structures and details can be improvised on the spot to fit existing conditions.
This project is the office relocation of Smart Checkout Inc., the company behind Pay Light, a payment service developed for dental clinics. For their new office, the client sought a space that itself embodied innovation and signaled the next step in their business. To achieve this, we designed a symbolic central feature occupying about one-third of the main work area—a carved-out mass that functions as multipurpose furniture. It serves as a place where employees can casually gather for conversations or host seminars and other events. Around this centerpiece, we arranged Herman Miller office furniture that balances design and functionality, allowing employees to choose the most suitable setting for their work. In this way, the office provides a flexible and comfortable environment that adapts to diverse working styles.

Located in Nagoya, this showroom for CREATORE with PLUS serves as a strategic hub for reimagining modern work environments. As the boundaries between the office and remote work continue to blur, the design adopts the concept of Work in Life, reconfiguring the office building as a continuous sequence of diverse, lived-in environments.While the primary function is to showcase commercial products, the design prioritizes a versatile exhibition space where shifting viewpoints and reconfigurable layouts mirror the fluidity of contemporary work styles. The spatial composition integrates varying scales—ranging from intimate residential settings to more expansive, urban-inspired zones—where furniture, objects, and people converge. Through a series of large, intentional openings and interconnected pathways, these distinct areas coalesce into a singular, cohesive interior landscape.

We designed a sales office for Kuribara Medical Instruments, a medical equipment dealer which has more than 20 branch offices mainly in the Kanto region. Based on the company’s request to create an office that fits the company’s brand image and the way employees work, the plan includes a space where people inside and outside the company can gather and interact with each other. The company is also looking to renew other branches in the future.
