該項(xiàng)目位于法國(guó)塞爾吉行政區(qū)公園中心，旨在通過大學(xué)食堂的重組為校園生活的中心設(shè)施賦予新的活力。原建筑建造于1993 年，得益于其所在地形和開放于公共景觀的特質(zhì)，它有幸被納入弗朗索瓦·密特朗公園內(nèi)部。該設(shè)施很好地融入了行人網(wǎng)絡(luò)，且恰好位于巴黎-賽納大學(xué)區(qū)和Val d'Oise 行政區(qū)的兩條主要道路的交匯處。

既有建筑以謹(jǐn)慎的姿態(tài)嵌入地形，雖然擁有優(yōu)越的位置，但可見性較為缺乏，且內(nèi)部空間與外部的聯(lián)系較弱。基于這些觀察，食堂的重組項(xiàng)目提供了重新利用和改善當(dāng)?shù)鼐坝^環(huán)境的機(jī)會(huì)，以證明它可以成為公園中強(qiáng)有力的組成部分，在融入環(huán)境的同時(shí)發(fā)揮必要的功能。舊建筑本身也展現(xiàn)了良好的建筑品質(zhì)：耐用的預(yù)制混凝土外墻、合理且靈活的建筑系統(tǒng)，以及豐富的用戶功能（路徑、樓梯和門窗等）。

本著突出既有建筑內(nèi)在品質(zhì)的意圖，項(xiàng)目團(tuán)隊(duì)提出了一個(gè)具有雙重目標(biāo)的規(guī)劃方案：對(duì)2000 平方米的食堂空間進(jìn)行深度改造，并在此基礎(chǔ)上增加一個(gè)新的“亭子”結(jié)構(gòu)，作為對(duì)食堂基礎(chǔ)功能的補(bǔ)充。

功能空間被分布在既有的兩個(gè)樓層中，而由于地形的變化，這兩個(gè)樓層可以從同一水平高度上進(jìn)入。用餐區(qū)設(shè)置在花園層，構(gòu)成了一個(gè)半地下的硬質(zhì)基座，它開放于公園北側(cè)，后部容納了廚房。加強(qiáng)室內(nèi)外的連接是干預(yù)過程中的一個(gè)重要部分，旨在為用餐區(qū)帶來更充裕的光線和視野，同時(shí)改善使用體驗(yàn)。為了實(shí)現(xiàn)這一目標(biāo)，原先的窗臺(tái)被拆除以擴(kuò)大立面開窗面積，擋土墻也被移走，從而可以重新塑造傾斜的地面。新修建的玻璃立面讓食堂的入口在公園中更加清晰可見。

憑借克制且經(jīng)濟(jì)的設(shè)計(jì)，該項(xiàng)目展示了如何在既有建筑的基礎(chǔ)上對(duì)普通的功能（如食堂）進(jìn)行重新定位，通過建筑空間的變化來滿足新的需要。

Located in the heart of Cergy,the existing refectory,erected in 1993,has the privilege of being set in the Fran?ois Mitterrand Park.Discreetly embedded in the topography,it faces a paradox: while benefiting from a privileged position,the refectory suffers both from a lack of visibility and from interior spaces that are little enhanced by its lack of links with the outside.

The restructuring project is thus an opportunity to reappropriate and inhabit the landscape qualities of the site,in order to affirm it as a strong component of the park,well anchored in its context and uses.The original building also displays genuine architectural qualities: a durable,prefabricated,deactivated concrete envelope,a traced and flexible construction system,and a wealth of user features.

The project develops a double programmatic component: the in-depth renovation of the refectory's 2000 m2,and the addition of an extension,called the kiosk,enriching the refectory' s initial offer.

The program is spread over the two original floors,accessible on the same level thanks to the topographical movements of the land.Forming a semi-subterranean mineral base,the garden level includes the dining room-which opens on the park -and the kitchens -in its rear part.The interventions consist in reinforcing the relationship between the interior and the exterior,in order to bring more light and views to the dining areas,and to enhance their uses.Thus,the openings in the fa?ade were enlarged by removing the spandrels,the sloping ground was reshaped following the removal of the retaining wall and the new glazed fa?ade became an opportunity to create more visible entrances.
