项目 - 在对工作空间设计的大胆重构中，建筑事务所 OpenA 将东京赤坂地区的一家前传统日式料亭改造为广告公司 Hakuhodo Kettle 的革命性办公空间，不仅对传统的公司等级制度提出了有力的挑战，也回应了后疫情时代工作文化的演变。

这座两层建筑位于赤坂繁华街道之外的一条静谧小巷中，改造刻意颠覆了料亭原本封闭、私密的特性——料亭传统上是进行私下商务洽谈的场所。建筑师巧妙地在建筑封闭的结构中“打孔”，打造出开放流动的空间，以建筑幽默的方式象征性地解构旧有权力结构。

项目的核心是一张醒目的圆形桌，位于穿过传统暖帘（noren）后一个圆形、解构式的入口空间内。圆形这一形态天然排斥等级制度，并自公司创立以来便成为其理念基石。这一设计不仅是公司扁平化组织结构和自由创意交流承诺的具象体现，更赋予了办公空间新的象征意义。

该项目的独特之处在于它彻底颠覆了传统玻璃与钢筋的办公高楼模式。相较于向天空发展，这一办公空间刻意与街道层面产生互动，鼓励自发的交流，并挑战公共与私人空间的界限。改造既保留了建筑的历史元素，又融入了现代设计手法，在传统与创新之间营造出张力与平衡。

这座改造项目代表了后疫情时代办公空间设计的新范式——一个以人与人之间的联系和创意协作优先于传统公司规制的工作场所。通过这一富有深意的改造，OpenA 不仅打造了一间办公室，更塑造了一份关于未来工作的空间宣言。

Project - In a bold reimagining of workspace design, architecture firm OpenA has transformed a former traditional Japanese restaurant (ryotei) in Tokyo's Akasaka district into a revolutionary office space for advertising agency Hakuhodo Kettle. The project, led by Masanori Baba and Kazutaka Ohashi, stands as a powerful statement against conventional corporate hierarchies while addressing the evolving nature of post-pandemic work culture.

Nestled in a quiet alley away from Akasaka's bustling streets, the two-story renovation deliberately subverts the secretive nature of its former life as a ryotei – traditionally a space for private business dealings behind closed doors. The architects have ingeniously "punctured" the building's enclosed structure, creating an open, flowing environment that symbolically dismantles old power structures through architectural humor.

The project's centerpiece is a striking circular table positioned in a round, deconstructed entrance space beyond the traditional noren curtains. This circular motif, a shape that inherently rejects hierarchy, has been a cornerstone of the company's philosophy since its inception. The design serves as a physical manifestation of their commitment to flat organizational structure and free-flowing creative exchange.

What sets this project apart is its radical departure from the typical glass-and-steel office tower. Instead of retreating into the sky, the workspace deliberately engages with street level, inviting spontaneous interactions and challenging the boundary between public and private space. The renovation maintains the building's historical elements while introducing contemporary interventions, creating a dynamic tension between preservation and innovation.

The 512.45-square-meter renovation, completed in August 2023, represents a new paradigm for post-pandemic workplace design – one that prioritizes human connection and creative collaboration over traditional corporate formality. Through this thoughtful transformation, OpenA has created more than just an office; they've designed a spatial manifesto for the future of work.

Design Team - Founded in 2003 by visionary architect Masataka Baba, Open A Ltd. has established itself as a leading architectural design firm that transcends traditional boundaries of architectural practice. Based in Tokyo's historic Nihonbashi district, with additional offices in Osaka and Sumida, the firm has evolved into a multidisciplinary powerhouse that combines architectural excellence with social innovation.

Under the leadership of President Masataka Baba, Creative Director Kazutaka Ohashi, and Director Seiji Hashimoto, Open A has cultivated a distinctive approach to architectural design that emphasizes adaptive reuse, urban regeneration, and cultural placemaking. The firm's portfolio encompasses a diverse range of projects, from urban-scale developments to innovative temporary structures, exemplified in recent notable works such as "Slit Park YURAKUCHO" (2022) and "iti SETOUCHI" (2022).

The practice's expertise spans architectural design and supervision, interior architecture, urban planning, and real estate development, with a particular focus on creating socially responsive environments. Their pioneering projects include "Tokyo R Real Estate" and "INN THE PARK," demonstrating their commitment to reimagining public spaces and urban functionality.

Operating as a registered first-class architectural firm (Tokyo Governor Registration No. 53091), Open A has assembled a talented team of over 30 professionals, including architects, urban planners, and creative specialists, all dedicated to pushing the boundaries of architectural possibility while addressing contemporary social challenges.
