東京花園露臺紀尾井町位于東京著名的千代田區(qū)，是一個綜合開發(fā)項目，積極響應該地區(qū)的歷史和文化背景。該項目由兩座高層塔樓組成，坐落于商業(yè)裙樓上方，裙樓沿斜坡基地順勢而建，通過強調退距和優(yōu)雅的設計減少了對周圍環(huán)境的影響。

在日本帝國的江戶時代，該街區(qū)內有座被護城河環(huán)繞的宅邸。200多年后，改造為著名的赤坂格蘭王子大飯店，這是上世紀八十年代東京建筑的代表，與幾座政府大樓相毗鄰。業(yè)主希望對過時的酒店進行重新改造，同時保持其原有體量，以免破壞其與周圍環(huán)境的關系?？傮w來說，這一項目需要細致地考慮地處東京中心地區(qū)具有重要意義的綜合街區(qū)風貌。

新建大樓堆疊的體量形成了敏感而平衡的建筑外形，讓人聯想其日本傳統(tǒng)的“珠寶盒子”，并參考了前酒店建筑師丹下建三的作品風格。體量較小的百米高住宅塔樓與主塔的堆疊體量相呼應，其暖色調、青銅色金屬面板外立面與主塔白色花崗巖和玻璃幕墻形成鮮明對比。事實上，主塔樓折疊立面的連接有助于將簡單的建筑造型變?yōu)橥庥^優(yōu)美的可持續(xù)建筑。經過細致的太陽輻射研究，確定了整個玻璃幕墻重復的準確角度，從標準的45度角開始，設計團隊對最佳位置進行了測試，以確保足夠的采光和遮陽，以及符合業(yè)主提出的每層周邊空間要求。團隊沒有采用現澆筑混凝土的常規(guī)做法，而是選擇使用預制模具鑄造樓板，精確匹配每塊樓板的立面角度。經過詳細審查，大廳選用來自意大利比薩附近工廠生產的華麗的卡拉拉大理石。

Located in Tokyo’s prominent Chiyoda Ward, Tokyo Garden Terrace Kioicho is a mixed-use development that elegantly responds to its historical and cultural context. Comprising two high-rise towers, which together sit atop a retail podium that cascades down the sloping site, the project reduces its impact on the surrounding context with a design that emphasizes setbacks and elegant articulations.

During the Edo Period of Imperial Japan, the neighborhood housed a palace surrounded by a moat.Over 200 years later, the particular site held the prominent Grand Prince Hotel Akasaka, a 1980’s staple of Tokyo architecture in close proximity to several government buildings. The client wanted to redevelop the outdated hotel while maintaining its original massing so as not to disturb its relationship to its surroundings. As a whole, the development amounts to a graceful negotiation of an important and complex site in the heart of historic Tokyo.

The new building’s stacked volumes generate a sensitive and balanced form, which both recalls the traditional Japanese motif of “jubako” and references the work of Kenzo Tange, the prior hotel’s architect. The smaller, 100-meter residential tower echoes the stacked volumes of its companion and plays with materiality;its facade of warm, bronze-colored metal panels contrast the white granite and glass curtain wall of the mixed-use tower. In fact, the articulation of the main tower’s folding facade contributed to their refinement,transforming the simple forms into both sustainable and beautiful buildings. Multiple solar radiation studies informed the exact angle to be repeated across the glass curtain wall; starting with a standard 45-degree angle, the design team tested the best possible position to ensure sufficient daylighting and shading as well as comply with the client’s desired perimeter area for each floor plate. Defying the typical practice of pouring concrete on site, the team opted to use a cast the floor slabs with a prefabricated mould, matching exactly the angularity of the facade in individual pieces. The beautiful scrunity of this process translates to the lobby’s magnificent Carrara marble, personally chosen from a foundry near Pisa, Italy.
