位于創(chuàng)盟國(guó)際J-office辦公區(qū)后院的茶室是對(duì)基地上原有的一棟屋頂已經(jīng)塌掉的倉(cāng)庫(kù)房的再建?；乇旧順O為局促，三向面墻，只有一個(gè)方向朝向一個(gè)有水池的后院，同時(shí)整個(gè)建筑對(duì)空間的索取也因?yàn)楝F(xiàn)有的一顆大樹而受到很大限制，而設(shè)計(jì)的結(jié)果也表現(xiàn)為一種綜合了封閉與開敞、占有與妥協(xié)、趣味空間與邏輯建造等多種復(fù)雜關(guān)系之后的和諧。整個(gè)建筑貼合基地空間，平面布局呈現(xiàn)為一個(gè)邏輯關(guān)系模糊的四邊形，卻也因此獲得了對(duì)空間的最大索取。整個(gè)建筑在布局上分為3部分，朝向后院一側(cè)布置相對(duì)公共性的開敞空間，一層茶室，二層圖書室，同時(shí)在二層圖書室伸出一個(gè)三角型的小平臺(tái)將現(xiàn)存樹木加以包裹，使得樹木和建筑本身融為一體。而背向后院一側(cè)布置休息室、圖書室以及輔助服務(wù)空間等相對(duì)私密的空間；公共空間與私密空間之間通過(guò)一個(gè)趣味性的連接空間得以串連。

連接空間是一個(gè)通過(guò)扭轉(zhuǎn)放樣得到的非線性六面體，將前后兩側(cè)的四邊形平面去掉后，連接空間將兩側(cè)屬性不同的功能空間加以融合，樓梯空間的置入既解決了茶室的豎向交通問(wèn)題，又為二層圖書室貢獻(xiàn)了一個(gè)可以看到現(xiàn)存樹木的內(nèi)向小庭院。而連接空間也為本來(lái)平淡的基本功能空間創(chuàng)造了新的空間感受，一層茶室空間出現(xiàn)了從平直空間向豎向空間的突變，而二層圖書室的空間也因?yàn)槿の犊臻g的存在而獲得了獨(dú)有的場(chǎng)所感。

連接空間是一個(gè)無(wú)法通過(guò)平面圖紙表述的三維異形體，我們?cè)赗hino中完成了對(duì)形體的基本推敲以及空間的把握，但這樣的數(shù)字模型很難直接轉(zhuǎn)化為可以指導(dǎo)工人進(jìn)行施工的信息。同時(shí)工人手工施工的現(xiàn)有限制條件迫使設(shè)計(jì)師在提交施工方案時(shí)必須同時(shí)給出解決措施以實(shí)現(xiàn)前沿?cái)?shù)字化設(shè)計(jì)與中國(guó)本土低技施工現(xiàn)實(shí)的結(jié)合。我們首先在數(shù)字軟件中將曲面掃描過(guò)的多根結(jié)構(gòu)骨架線進(jìn)行提取，使得曲面形式通過(guò)相互交錯(cuò)的直線得到概括，再將直線進(jìn)行等分以實(shí)現(xiàn)直線間的曲面擬合，等分的距離控制在木模板可擬合的尺寸之內(nèi)，這樣數(shù)字化的放樣就轉(zhuǎn)化為手工可控制的形態(tài)。再根據(jù)這樣的直線擬合關(guān)系制作1:1的木骨架模具，在這一骨架基礎(chǔ)上蒙上細(xì)分后的木模板，由此形成一個(gè)完整的空間曲面模板構(gòu)架。模板構(gòu)架根據(jù)施工工序切分為上下兩次搭造。樓板的澆筑基本和普通的混凝土相一致，唯一區(qū)別就是鋼筋的鋪設(shè)也與模板的直線取向相一致。鋪設(shè)鋼筋后混凝土的澆筑也通過(guò)手工來(lái)完成，并最終形成了現(xiàn)有的實(shí)體效果。模板的痕跡在施工后完全保留，全手工的施工模式使得混凝土的表面出現(xiàn)了很多類似起泡、模板脫膠、鋼絲外露等很多質(zhì)量缺憾，但曲面的獨(dú)特形式卻使得這些得以弱化。雖然無(wú)論是模板布置還是手工澆筑都具有一定的造型誤差，但這一數(shù)字化設(shè)計(jì)與低技手工施工相結(jié)合的方式對(duì)建造數(shù)字化建筑的探討也具有了特別的意義。

The Tea House,located in the backyard of Archi-Union's J-office,is constructed from the salvaged parts of an existing warehouse with collapsed roofs.The site was a challenge to design with considerable restrictions due to enclosing walls that only leaves one side facing towards an open space that contains a pool.The space was further restricted by a giant tree.The design ventures at harmony by integrating enclosure and openness,delightful space and logical construction and other complicated relations.This building responds to the surroundings of the site environment; the layout is a rectangle without explicit logic which maximizes the utility of space,divided into three parts.The covered public area is formed towards the open space with the pool,with an enclosed tea house on the ground floor.The library is placed on the first floor from which a small triangular balcony extends to embrace the existing tree.Spaces of more privacy such as a lounge,reading room and service room are arranged at the rear of the building; a delightful transitional space was created to connect the public space and the private spaces.

The transitional space is designed around a twisted nonlinear hexagonal staircase,which connects the functional spaces.The stair resolves the vertical transportation from the tea house and the library,providing an inner courtyard close to the reading room to watch the existing tree.The space is designed to bring a new experience to an ordinary functional space.Linear space suddenly changes into an expressive form,surging from the tea house then transforming into a tranquil space for the library on the floor above,making the reading room a unique place to experience.

The volume is a three-dimensional irregular shape beyond the capability of representation in blueprints.The twisting shape was designed and scrutinized with the software of Grasshopper,an algorithmic plug-in for Rhino.However it is difficult to translate the form into two-dimensional blueprints for construction.The constraints of manual construction obliged us to invent solutions at the time of construction to realize the advanced digital design with local low-tech construction techniques.Firstly we abstracted the structural skeleton which was subsequently scanned with the software.The curvilinear shape was then recalculated through interlacing straight lines which consist of regulated surfaces to fill in the void.The spacing was set to the dimension of timber,thus the digital "setting out" could be easily translated into a manually constructible shape.A full size timber model was erected following the same logic as the digital model; a subdivided timber shuttering covered this framework to create a curved formwork.The formwork was built through a series of upper and lower layers according to the construction sequence.The casting was almost the same as ordinary concrete casting,reinforced with re-bars following the straight lines of regulated surface.Concrete casting after the reinforced bar was completed by manual labor to achieve the finishing effect.The traces of the timber formwork remained imprinted on poured concrete after construction,with quality defects such as bubbles,adhesive failures and re-bar exposure present due to the manual construction–defects,however,that are obscured by the unique curved shape.Although there are errors in the work,planning,manual casting,and a combination of digital design and low-tech manual construction altogether provide a great opportunity to explore the possibilities of digital architecture.
