好的建筑,生于場地,生成場所。而人的體驗則構(gòu)成了場所的靈魂。

我們試圖在建筑與其外部空間之間建立一種新的關(guān)聯(lián)，從而創(chuàng)造出一種新的場所體驗。我們姑且將這種關(guān)聯(lián)稱為“多義性邊界”。

該項目是建筑規(guī)模近100萬平方米的北城中央公園居住區(qū)文化教育配套的一部分，在前期兼具項目展示中心的功能，后期則作為圖書館和兒童教育營地使用?；厥且粋€東西寬約260米、南北深約70米的矩形場地。用地南面則是占地面積近4萬平方米的城市公園，中央公園項目藉由此得名。在空曠的土地上描繪繁華的愿景，幾乎成為當(dāng)下大型項目展示區(qū)的共同使命。在中央公園項目這樣的場地上，設(shè)計面臨的挑戰(zhàn)一方面是如何形成一個鮮明而有力的城市界面從而與尺度巨大的城市公園相呼應(yīng)，共同創(chuàng)造一種先聲奪人的展示性。另一方面則是如何創(chuàng)造一個具有獨特體驗的場所以激發(fā)人們探索和參與的意愿。得益于項目未來的文化教育功能，我們首先可以賦予它一種即開放又具文化內(nèi)涵的場所特質(zhì)，進(jìn)而在此基調(diào)之上演繹功能，組織敘事。

A good building, born on a site and create a place And the human experience constitutes the soul of the place

We try to create a new relationship between building and its outer space, thus creating a new place experience. Let's call this association "ambiguous boundary" for the moment

The project is part of cultural and educational facilities for the nearly 1 million square meters Central Park residential area,The base is a rectangular field about 260 meters wide in east and west and about 70 meters wide in north and south, with the city park on the south which covers an area of nearly 40 thousand square meters, after which the Central Park project is named.

Depicting the bustling vision in the open land is almost a common mission for the exhibition hall of a large projects. In places like this project, the challenge for design, on one hand, is how to form a distinctive and powerful city interface to correspond with the huge city park, and jointly create a visual display. On the other hand, it is how to create a field of unique experience,so as to stimulate people's willingness to explore and participate. Benefiting from the future cultural and educational function of the project, we can first endow it with open and cultural characteristics, and then deduce the function and organize the narrative on this tone.

回顧中國傳統(tǒng)的建筑和園林空間，院落是構(gòu)成場所特質(zhì)最強(qiáng)的空間形態(tài)之一，它幾乎構(gòu)成了中國傳統(tǒng)建筑空間的核心特征。而界定院落的建筑界面則是墻和廊。這兩者也使得院落具有了不同的空間特色：一個圍合，一個滲透；一個封閉，一個開放。前者多見于街墻和宅邸，后者多見于園林與闊院。而兩者又往往結(jié)合使用，讓院落空間具有了更好的多樣性與故事性。

而在我們嘗試為界定院落空間創(chuàng)造一種新的建筑原型時，我們最終在墻和廊之間找到了結(jié)合點--它剛好是由短墻構(gòu)成的廊，伴隨不同的形態(tài)和模數(shù)的組合，形成對于院落空間的多樣化的界定方式，同時構(gòu)成多義的場所體驗。我們所說的“多義性邊界”也由此形成。它的形態(tài)如同從建筑的墻體之中游離出來，意在融于室外場所之中?！皦取庇幸粋€統(tǒng)一的整體尺度--6米高，4米寬，它界定了整個場地的邊界，同時創(chuàng)造了一個特殊的“回環(huán)景域”。當(dāng)邊界有了可以進(jìn)入的厚度，日常生活、藝術(shù)活動也就有了空間的載體，可以是小朋友放學(xué)后捉迷藏的樂園，也可以是社區(qū)文化藝術(shù)展廊。

墻廊圍合的，是中央的水庭，它的主體是一片淺水池。一如中國傳統(tǒng)園林，水構(gòu)成另一種界面，藉由鏡像創(chuàng)造放大的建筑尺度感和空間領(lǐng)域感，同時也模糊了天地的界限，本與建筑隔水相望的人們，則可以通過一條“弦道”，由場地之外，穿越水面，進(jìn)入建筑。而這個地坪標(biāo)高不斷變化的“弦道”，則讓這個穿越的過程因視線高度的不斷變化而產(chǎn)生不同的視覺經(jīng)驗。

Reviewing the traditional Chinese building and classic garden, courtyard is one of the most powerful spatial forms. It almost forms the core feature of Chinese traditional architectural space. And the building interface of the courtyard is the wall and corridor. The two also bring the courtyard different spatial characteristics: Enclosure or penetration,closed or open.The former is mostly found in street walls and mansions, and the latter is more common in gardens and courtyard. And the two are often used in combination, so that the courtyard space has a better diversity and story appeal.

While we try to create a new architectural prototype for the definition of the courtyard space, we finally find the combination between the wall and the corridor -- it is just the corridor composed of short wall,with the combination of different forms and modules, forming the diversity definition for courtyard space, also constituting a multiple place experience. This is what we call the "ambiguous boundary".Its form is free from the wall of the building, intended to melt in the outdoor place. "Wall corridor" has a unified whole scale, --6 meters high, 4 meters wide, which defines the boundaries of the entire site,while creating a special "circle scene domain". When the boundary has thickness , daily life and art activities then have a space vector, it can be a paradise for kids to play hide and seek after school and can also be a culture and art gallery of the community.

The wall corridor encloses the central water court, and its main body is a shallow pool. As Chinese traditional garden, water constitutes another interface to create an amplified architecture scale and space field sense, and also fuzzy the space boundaries, and the people on the other side of the building across the water can, through a "crescent path", go across the water to enter the building from the outside. And the "crescent path" with continuously changing elevation of the ground floor makes the process of crossing produce different visual experiences due to the change of the sight height.

當(dāng)人們穿越“弦道”，在屋檐之下推開大門，首先來到一個由一片對景實墻界定的門廳，門廳北側(cè)是小展示廳，這是進(jìn)入中廳的一道轉(zhuǎn)折空間，中廳是更大尺度的展廳，兩層高，通過天窗為空間帶來自然光，經(jīng)過屋頂折板的過濾，被塑造成數(shù)條光線，落在墻上，在一天之中，可以形成不同方向以及粗細(xì)的變化，如日晷般記錄時間的流逝。底景是螺旋樓梯和二層的廊橋，廊橋穿越中廳，連接兩個不同的能空間，上下兩層的人，在這里也能形成交流和對話。

由天窗龍骨與混凝土密肋梁組合形成的天窗構(gòu)件，兩者離縫的設(shè)計，在中午時分，能形成粗細(xì)不同的兩道光線，構(gòu)件截面的方向和組合方式，能為早上提供更大的入射角，而下午則是較小的入射角，從而遮擋掉大部分西曬。

東面和南面作為側(cè)廳，提供水吧、洽談和閱覽等功能，與外部庭院關(guān)聯(lián)，是室內(nèi)外空間的延續(xù)和滲透，尤其是南面的灰空間，作為兒童的趣味性活動場地，進(jìn)一步加強(qiáng)了這種延續(xù)關(guān)系。兩個側(cè)廳的外墻上，我們適當(dāng)?shù)貙χ脑O(shè)計語言進(jìn)行引申。整個空間中，我們并沒有強(qiáng)調(diào)軸線與儀式感，而是利用轉(zhuǎn)折與進(jìn)深表現(xiàn)空間的流動性。二三層由大小不同的教室構(gòu)成，教室圍繞兩層通高的庭院布置，庭院不僅是室外活動空間，也為教室?guī)砀玫淖匀徊晒獾耐L(fēng)。

在材料的選擇上，我們根據(jù)建筑體量與功能進(jìn)行清晰的劃分，一層的清水混凝土和二、三層的U型玻璃，一輕一重，一虛一實。清水混凝土表面光潔，質(zhì)感樸素而堅實，而我們通過“墻廊”這種特殊的構(gòu)成方式形成一個既穩(wěn)健又開放的界面；漫反射的U型玻璃質(zhì)感溫潤，而我們則將其作為建筑主體空間的包裹面，使之呈現(xiàn)出一種“半透的體積感”。二者不會形成強(qiáng)烈的反差，卻能在不同的光線變換下演繹出豐富的溫度和表情。

When people cross the "crescent path ", and push the door open under the eaves,they first come to the hall defined by a piece of scenery wall, in the north of the hall is a small exhibition room, which is a transition space into the central nave, and the central nave is a larger scale exhibition hall, two-storey high, with natural light coming into the space through the skylight, and after being filtered by the roof plate it is shaped into a plurality of lights, finally falling on the wall, in a day, it can change in different directions and thickness, like a sundial recording the passing of time.The background is a spiral staircase and bridges on the second floor which crosses the central nave, connecting two different space, so that people on the first floor and second floor can make exchanges and dialogue here.

The skylight components formed by the roof keel and concrete ribbed beam, thanks to the open joint design, form two rays of different thickness at noon, and the direction and combination of the component section can provide a greater incident angle in the morning and a smaller incident angle in the afternoon, thereby blocking out most western exposure.

As the side hall, the east side and south side provide water bar, negotiation and reading and other functions, and is the continuity and penetration of indoor and outdoor space by connecting with the outer courtyard, especially the gray space in the south, as the Children's playground, further enhancing the continuation relationship. On the exterior wall of the two side halls, we appropriately extend the design language of the wall column. In the whole space, we do not emphasize the axis and the sense of ceremony, but use the transition and depth to show the mobility of space. The second and third floors are made up of classrooms of different sizes, and the classrooms are arranged around the two-floor-high courtyard. The courtyard serves not only as an outdoor activity space, but also brings better ventilation and natural lighting for the classrooms.

In the choice of materials, we make clear division according to the building form and function, with concrete for the first floor and U type glass for the second floor and third floor, integrating the light and the heavy, the virtual and the real into an organic whole. The concrete surface is smooth, simple and solid, and the special wall corridor form a stable and open interface; and the U type glass of diffusere flection is moist in texture, which is made into the wrapping surface for main building space,displaying a "semi-transparent volume sense". The two will not form a strong contrast, but can generate rich temperature and expression in different lights.
