當代中國城市的快速擴張使城市和鄉村之間在沒來得及相互消化和融合之前已經相互擠合成為非城非村的某種獨特城市狀態，這種狀態尤其在城市新CBD 區域明顯，如棠下“握手樓”所在的廣州天河區。城市的野蠻成長似乎總在不斷地將舊有的城市肌理摧毀而使新的垂直（標準）城市得以憑空而生，不必顧及原有的城市歷史和脈絡。表面上是高效城市壓倒了舊有的自主村莊，但實質卻可能導致珠江三角洲城鎮系統就此戛然而止，城市從此變得粗暴和單一。

項目設計的基本設想是一個“三明治”式的垂直立體社區，即將原有的7 層標準單元式“握手”住宅樓的“底”和“頂”打造成社區的公共活動層，而中間維持單元式住宅的格局作為居住的私屬空間。原建筑的首層和二層采光和通風極差，建筑師將其轉換成純粹的室內空間，構建一個與周邊低層空間環境完全分離、公共交往和居住的復合空間，可以讓進入的人們暫時忘卻周邊的混雜和陰暗。從梯間出到屋面則豁然開朗，因此屋面是社區另外一個重要的公共生活和交往空間。三至七層作為主要的居住公寓樓層，在大體保持原有格局的前提下作微調以改善居住環境。

建筑的建構方式上忠實于上述“三明治”式的社區劃分。對于兩個公共區域的外墻，建筑師拆除了原有的墻體，并在擴展后的建筑邊線上建立一圈以混凝土植草磚為原型改進的砌塊墻體，創造了獨特的立面和墻體肌理，并反映真實的建構。而保持原有建筑格局的單元式公寓部分基本保留原有墻體及馬賽克飾面而體現建筑的實時性和在地性。原有窗外架設的各式各樣的金屬防盜網被統一拆除，取而代之的是整體連接上下新砌塊墻體的不銹鋼編織網體，以解決整體安全問題，同時為社區提供一個添加垂直綠化立面的基礎。□

The rapid expansion of contemporary Chinese cities has squeezed urban and rural areas together into a special non-urban-and-non-rural condition,before they have enough time and space to join and merge to each other,notably in the urban area near new CBD centre.Eighth Commune of Tangxia inside Tianhe District of Guangzhou locates exactly among this type of urban area.The brutal growth of the city seems to be constantly in the process of destroying the old urban fabric,leaving the new vertical(standardized) city to emerge without regard to the original urban history and context.The superficially efficient cities have overwhelmed the original autonomous villages,but in essence this may lead to an abrupt ending of the existing organic urban-rural system in the Pearl River Delta region.The city has since become generic and monolithic.

The basic idea on restoration of the"Shaking-hand housing" project is a "sandwich"type of vertical community:the "bottom" and"top" of the original seven-storied apartment building are restored to the public spatial layers,while the middle levels of apartment units are kept in their existing function.The ground floor and the first floor of the original building were poorly lit and airy,and thus the architect choose to envelope them into a purely indoor space to create a composite space to the residence,offering a protected common area isolated from the surrounding dark and humid environment.The roof,a totally open-air and lit outdoor space,is another vital area for public life and social interaction.The second to the sixth floors are the main living apartment levels,maintaining the original pattern on the premise of fine-tuning to improve the living condition.

The construction is consistent with the principle of the sandwich division of the community as mentioned above.Considering the poor logistic condition of the existing building,the architect removed the existing exterior walls of the two public layers and built a new linear masonry structure on the expanded building edge .The new masonry wall is stacked with altered #-shaped concrete grass-planting bricks,creating a unique fa?ade texture that reflects the real construction method.The fa?ade of the apartment floors maintains the original mosaic finish to inform the real-time and local dispositions of the building.The originally autonomous anti-theft metal lattices installed on existing fa?ade of has been cleared and replaced by an integrated stainless-steel network vertically joining the "top" and "bottom" public layers to provide an elegant solution to both the security and decorative demands of the residence.□
