迷人的灰空間——貫穿建築的半室外公共空間 激活商場的每個樓層
對於曼谷這樣的國際化城市，生活條件和空間形式都在不斷進化。曼谷城市密度高，室外空間有限，百姓急需新的適應熱帶氣候的室外生活空間。The Commons是一個位於城市中心的小商業項目，旨在創造一個活躍而舒適的室外空間，讓人們可以在一年四季享受其中。
For Bangkok, or any other modern-day cosmopolitan cities, living conditions and spatial form continue to evolve. Bangkokians are now yearning for new possibilities of outdoor living space that can effectively answer to the tropical heat and its dense living condition where there is not much space for the outdoor. ‘The Commons’, a small retail development in the city center, is an attempt to create a new active outdoor space where people can comfortably enjoy it at anytime of the year.

The Commons的主體是一個縱向的露天公共場所。底層為景觀，設有臺階、坡道、休息平臺、座椅、綠植和小涼亭等，整片區域處於三四層結構的陰影中，沒有陽光和雨水的侵擾，人們可以安心地在這裡進行各種活動。三層和四層圍繞中庭設置室外空間，佔去每層將近百分之三十的面積，與底層相連，形成了一個巨大的公共活動中庭。這裡在垂直和水平方向貫通整個建築，形成自然通風，此外還在天窗下的頂棚內設置了兩套工業風扇進行機械送風和排風，保證在特別炎熱的時候中庭空氣依舊可以流通。良好的通風和每一層精心設置的花園，讓這裡成為了一個充滿活力的半室外垂直城市空間，隨時歡迎人們來此閒逛和放鬆身心。
‘The Commons’ proposes a vertical open-air public space folding upward as a backbone of the building. It starts with ‘the Ground’ which is a landscape of steps and ramps integrated with platforms, seatings, planting and small kiosks. The area is well shaded by the third and the fourth floor structure above protecting the entire space from the sun and the rain. ‘The Ground’ vertically opens up through large voids on the upper floors, connecting to a large public open-air area occupying nearly thirty percent of each of the third and the fourth floor plate. The space vertically and horizontally flows in and out the entire building and allows for natural ventilation throughout. Two sets of industrial fans are incorporated into the ceiling screen below the skylight. One set draws hot air upward and out; the other set blows the wind downward to effectively increase the air movement in extra hot days. This airy semi-outdoor space is well incorporated with gardens on all levels. It becomes an active vertical urban living area. It is a place for strolling and relaxing at any time and in any seasons.

多層商業建築一直面臨的一個挑戰就是如何將顧客帶到建築高區，The Commons對此提出了自己的解決方案。建築師在寬敞的底層空間設置了一系列臺階和平臺，人們可以散著步，悠閒地從一層走到二層。三層和四層的開口進一步加強了垂直空間的連續性，遊客在底層可以清楚地看到樓上的店鋪，從而自然地被吸引到其他樓層。
‘The Commons’ also provides a solution answering to a classic challenge of a multi-storey retail building on how to draw people upward to the upper levels. The wide ‘Ground’ with its gradual series of steps and platforms connecting the street level to the second floor naturally draws people to walk up leisurely. A series of openings in the third and the fourth floor further enhance a continuity of the vertical space. Shops on the upper levels are clearly seen from different angles from ‘the Ground’. People flow to every floor effortlessly.

儘管項目想要打通立面加強通風，但是種類繁多的商店讓建築的外觀看上去十分凌亂。為了解決這個問題，建築師在上層立面上安裝了一層薄薄的鋼網，一定程度上消解不同商店之間的差異，創造了一個輕盈而又統一的建築外觀。同時，這層鋼網滿足了通風需求，並且讓室內外之間可以進行視覺交流。
A building skin on the upper floors answers to another challenge. While the project wants to open up the facade for a through ventilation, the different identities of various shops on the façade would have made the building appear to be fragmented. The project applies a thin sheer steel mesh over the façade to partially mask off the differences among the shops providing a unified surface while allowing for visual transparency from the inside, a through ventilation, and the lightness appearance from the outside.

中庭的頂部採用向上打光，彷彿懸浮在空中，給公共空間製造出一種安逸的氛圍。鐵網立面的照明時亮時暗，緩慢交替。燈光打開時，建築的表皮被呈現在人們面前；隨著燈光變暗，表皮變得透明，內部空間逐漸顯現出來，明暗的變化讓建築彷彿擁有了生命。
The ceiling of ‘the Ground’ is carefully up-lighted creating a floating effect to the mass above and give a cozy atmosphere to the area. The exterior light on the meshed façade fades in and out slowly. With light, the surface of the building skin comes into presence, while when the light fades away, the façade becomes transparent and briefly reveals what is inside. It feels as if the walls could breathe and the building itself is alive.
