场地利用与成本效益：该项目充分利用了场地的自然地形，通过最小化建设成本和时间，实现了快速入驻的目标。梯形地块的3.6米高差被巧妙利用，无需额外挖掘即可建造地下停车场，展现了对现有条件的高效利用和对成本的严格控制。

设计与公司形象的融合：建筑的设计不仅体现了客户作为土木工程公司的专业特色，还将公司的核心价值观融入建筑之中。混凝土衬砌的概念被创新性地应用到办公室设计中，使得建筑内外都展现出公司在地下隧道建设领域的专业形象和实力。

多功能性与空间多样性：建筑内部空间设计灵活多变，能够适应不同的用途和需求。从地下停车场到咖啡馆、展览空间以及办公和会议空间，每一层的设计都根据其功能进行了精心调整。这种设计不仅满足了当前的使用需求，也为未来可能的变化提供了多功能性。

建筑师提供的文本描述如下：该场地位于光进桥南端，一个长期未开发的梯形地块上。前面的道路被称为“天湖洞工具街”，虽然有些繁忙，但一旦建筑完成，它将提供一个由阿查山环绕的汉江的如画景观。前后道路之间有3.6米的高差，这使得无需额外挖掘即可轻松建造地下停车场。客户决定在这块地上建造一个办公室，目的是通过利用现有地形来最小化建设成本和时间，以便快速入驻。由于邻近商业设施的性质，平面图在很大程度上受到法规和经济因素的影响，需要仔细考虑立面和材料表现。

Text description provided by the architects. The site is located at the southern end of Gwangjin Bridge, on a trapezoidal plot that had long been left undeveloped. The road in front, known as "Cheonho-dong Tool Street," is somewhat bustling, but once the building is completed, it will offer a picturesque view of the Han River framed by Achasan Mountain. The front and rear roads, with a 3.6-meter elevation difference, allow for easy underground parking without additional excavation. The client decided to build an office on this site, aiming to minimize construction costs and time by utilizing the existing terrain for a quick move-in. Due to the nature of neighborhood commercial facilities, the floor plan was significantly influenced by regulations and economic factors, requiring careful consideration of the façade and material expression.

客户是一家领先的土木工程公司，专门使用隧道掘进机（TBM）进行地下隧道和电力管道建设。他们目前的办公大楼建于十多年前，看起来有些普通，无法充分代表公司的独特价值。鉴于公司的发展，他们表示将来可能会考虑出售该物业以换取更大的办公空间。尽管建筑物的用途非常明确，但其未来可能的多功能性也是一个考虑因素。尽管如此，重要的是要在建筑中体现出公司的独特价值。这种愿望不仅来自于客户的要求，也来自于建筑师希望为一家历史悠久的公司创造一个合适的空间。
The client is a leading civil construction firm specializing in underground tunnel and power duct construction using Tunnel Boring Machines (TBM). Their current office building, constructed over a decade ago, appeared somewhat ordinary in representing the company's unique values. Given the company's growth, they indicated that they might consider selling the property for a larger office in the future. Despite the clear intended use of the building, its potential versatility for future purposes was also a consideration. Nevertheless, it was crucial to reflect the company's unique values in the architecture. This aspiration stemmed not only from the client's requirements but also from the architect's desire to create a fitting space for a long-established company.

“混凝土衬砌”指的是在隧道建设过程中安装在最内层的混凝土结构。这种平滑、均匀厚度的混凝土构件既作为隧道的结构，也作为隧道的完成面，独特地定义了内部空间。在设计过程中，我主动参观了各种地下施工现场，以研究客户和公司，这加深了我对混凝土衬砌的欣赏，并激励我将其纳入办公室设计中。
"Concrete lining" refers to the concrete structure installed on the innermost layer during tunnel construction. This smooth, uniformly thick concrete element serves as both the structure and the finish of the tunnel, defining the internal space uniquely. During the design process, I proactively visited various underground construction sites to study the client and the company, which deepened my appreciation for concrete lining and motivated me to incorporate it into the office design.

暴露的混凝土结构从地面开始，厚度为450毫米，它定义了整个建筑的所有空间，贯穿楼层、墙壁和天花板。这种形式在建筑外观上可见，创造了一种观看隧道横截面的错觉，象征着公司的身份，并在揭示建筑空间组合原则的同时，使设计与众不同。
The exposed concrete structure, beginning from the ground with a thickness of 450mm, defines all spaces throughout the building as it flows through floors, walls, and ceilings. This form, visible on the building's exterior, creates an illusion of viewing a tunnel cross-section, symbolizing the company's identity and differentiating the design while revealing the principles of architectural spatial composition.

地下一层设有可从后门进入的停车场，一楼设有可从主街进入的咖啡馆，二楼用作展览空间，三至六楼设有办公和会议空间。混凝土衬里会根据每层楼的不同用途自然地调整方向、视野和阳光。在建筑物的形状改变了地板宽度的区域，简单地反转衬里的方向就可以在内部空间和立面上创造多样性。虽然这个概念很简单，但各种技术方法，如平板结构、后张技术、组合墙、钢结构和混凝土结构，都是可行的；在其实现中利用了钢筋混凝土柱和外露混凝土饰面。室内空间的设计是为了在天花板上展示各种设施和照明，与建筑概念相一致。
The basement level accommodates parking accessible from the rear road, the first floor features a café accessible from the main street, the second floor serves as an exhibition space, and the third to sixth floors contain office and meeting spaces. The concrete lining naturally adjusts to orientation, views, and sunlight according to the varying uses on each floor. In areas where the building's shape alters the floor width, simply reversing the direction of the lining creates diversity in both internal space and façade. Although this concept is straightforward, various technical methods such as flat slab structures, post-tensioning techniques, gang form walls, steel & reinforced concrete columns, and exposed concrete finishes were utilized in its realization. The interior spaces were designed to expose various facilities and lighting on the ceiling, aligning with the architectural concept.

随着客户搬进他们的新办公室，标志着公司成立30周年，他们已经重塑了品牌，并进入了一个新时代。希望这个充满公司价值观的特殊空间将成为许多珍贵回忆的所在地。
As the client moves into their new office, marking the 30th anniversary of the company, they have rebranded and are entering a new era. It is hoped that this special space, infused with the company's values, will become a site of many cherished memories.
