隱身於日本東京高圓寺站旁旗杆地，照內創打造面寬僅兩公尺的辦公建築
.
日本東京隱藏著一棟特別的企業總部，建築物座落於高圓寺站附近的旗竿地 上，臨街面寬僅有兩公尺；整體空間包含地上三層與地下一層，設計團隊株式會社SO&CO.一級建築士事務所試圖擺脫帶有剪力牆的傳統鋼筋混凝土結構框架限制，進一步擴展混凝土建材的發展潛力。
.
設計過程並未受限於結構系統觀念，建築師照內創帶領團隊探索分散的空間條件，將柱子與牆壁的尺寸限制在30公分以內，並且定義樑下的最小淨空高度。在種種設定條件下，設計團隊確保所需結構安全與空間尺寸，盡可能配置數量最少的柱子與剪力牆。
.
因應不同的空間需求，團隊不斷調整樑的寬度與深度，同時增減或移動柱子與樑的位置。許多具有不同斷面的樑因此要互相連接，各自扮演著重要的支撐角色。
.
懸臂樑負責支撐樓梯的Ｈ型鋼樑，中間樑防止柱子彎曲變形並減輕結構應力，同時還有因為下層平面圖需求而產生的轉換樑。
.
多樣化且帶有些許偶然性的結構連接方式，加上30公分見方的混凝土構件，賦予這棟辦公建築以及混凝土本身豐富的面向；即使未來為了不同需要而必須拆除原本的乾式隔牆、窗框與鋼樓梯，只留下最原始的混凝土結構，建築團隊依然期盼大樓能持續作為通往未來的可能。
.
建築業主是一家長期在高圓寺總部與零售店鋪的公司，專門開發販售公仔、滑步車、服飾與配件等多樣化商品，企盼提供能隨時應對未來變化的創意基地，團隊刻意避開僵硬且同質化的空間配置，為這家不斷進化的企業打造出對城市開放的嶄新起點。在佔地面積僅50平方公尺的垂直空間裡，滿載著企業對於發展的多種想像。

有看過面寬只有兩公尺的辦公大樓嗎？日本東京高圓寺站附近就有一棟蓋在狹長「旗竿地」上的企業總部！
設計團隊打破傳統鋼筋混凝土框架，把柱子跟牆壁厚度縮減到三百公厘以內。整棟建築地上三層加地下一層，裡面充滿各種大小不一的樑柱互相支撐，把空間運用發揮到極致。該處是專門賣公仔和滑步車等潮流商品公司的創意基地，整體空間完全不死板，反而充滿彈性與變化。
大家覺得能在超窄的基地蓋出兼具美感與實用性的辦公室是不是超酷？趕快分享給喜歡建築設計的朋友看看！
This headquarters building is situated on a flagpole-shaped lot near Koenji Station, with a frontage of just 2 meters. The building comprises three above-ground stories and one basement level. We sought to free the design from the constraints imposed by the conventional rationality of reinforced concrete structure frames with shear walls, and to expand the roles of concrete.
Rather than being constrained by the structural system, we responded to a three-dimensionally fragmented spatial condition by limiting the dimensions of columns and walls to 300 mm or less and defining only the minimum clearance beneath the beams. Within these parameters, the minimum number of columns and shear walls were positioned while ensuring the required structural and spatial dimensions.
Through continuous adjustments to beam widths, beam depths, and the addition, removal, or relocation of columns and beams, numerous beams with varying cross-sections came to be interconnected, each playing its own role: Cantilever beams supporting the H-steel beams of the staircase, intermediate beams that prevent columns from buckling, reduce slenderness ratios, and alleviate structural stresses, as well as a transfer beam resulting from the floor plan of the lower level.
The accumulation of diverse and somewhat fortuitous connections, as well as the 300 mm square concrete elements, gave this building, and the concrete itself, a multifaceted meaning. Even after the drywall, steel window frames, and steel staircase are removed, leaving only the concrete behind, we hope this building will continue to serve as a bridge to the future.
This office building is owned by a company that has long maintained its headquarters and retail stores in Koenji, where it develops and sells a wide variety of products, including action figures, balance bikes, apparel, and accessories. As a base for this creative and evolving business, we have created a "place of beginnings" that is open to the city and responsive to future changes, rather than a rigid, homogeneous space.
