在上海市实验学校（SES）校园真正的心脏位置是一处正方形的庭院，被教学楼、综合楼、图书馆和连廊等建筑围合。与附近阳光工作室以及梯田中庭等高人气的空间相比，这处封闭式的绿地形成了强烈的反差。

In the real heart position of SES (Shanghai Experimental School) campus is a yard in square shape, it is surrounded by the buildings of Teaching Building, Complex Building, library and corridor, etc. Compared with the popular space, such as the nearby Sunshine Studio and terrace atrium, etc., the closed green land forms a sharp contrast.

现状庭院中类似篮球场的路径也有些令人费解：除图形外，没有太多作用。既起不到交通联系的作用，也支持不了更多的活动。转换到普通视点观察，甚至连图形都不大看得出来。10年前种下的绿化如今虽然茂盛，但已经显得有些杂乱，几乎从各个角度都遮挡了视线。还不止此，贴边矮墙和栏杆又加设了一道隔断，使得整个庭院与周边的关系更加剥离。与庭院一墙之隔的综合楼一楼大厅就更不用提了，可能也是觉得绿化面貌不佳，朝向庭院的落地玻璃上干脆全部贴上了海报，严实密闭。

At present, there are paths like the lines in the basketball court, which is beyond comprehension: it is useless except for the diagram. The paths have no rules of traffic and connection, nor support more activities. And even the diagram cannot be recognized when changing to normal viewpoint. The plants planted 10 years ago are plentiful, however, they are quite mussy, and plants have kept out the sight from all perspectives. Besides, the facing toe wall and the handrail just like a partition which makes the whole yard to be more separate from the surroundings. Not to mention the entrance hall of the Complex Building which is only being separated from the yard only by a wall. The French windows facing to the yard has been posted with posters for the poor greening appearance, and the windows are closed firmly.

改造后的庭院，采用了全通透的设计，四周均可进入，内部也能停留。综合楼一楼大厅内与对面的教学楼的视线联系被建立起来，校园空间的整体感得到显著提升。整体打开后，通过交通空间的置换合并，拓展出书架和工作台组成的非正式学习空间，满足了更多学生的使用需求。

After reconstructing, the yard uses transparent design, all the persons can enter the yard from all directions, and they can stay in the center of the yard. The line of sight between the entrance hall of in the first floor of the Complex Building and the opposite Teaching Building has been connected, the associative perception of the school space has been significantly improved. After the yard has been opened completely, the informal learning space combined by bookshelf and workbench will be expanded by replacing and integrating the transport space to satisfy the using demands of more students.

新的庭院以树木和桌子为主要元素，被称为树桌花园。保留下的11棵树木都是非常普通的品种，一点都不名贵。但是经过多年的生长，已经形成了绿意盎然的上层覆盖，延续这个元素，也是在延续校园的记忆，同时也是对绿色的尊重。

The new yard takes trees and desks as the main elements, therefore, it is called as Tree Desk Garden. The 11 remaining trees are normal species, they are not rare at all. And after growing for several years, they have formed vivifying upper cover, continuing this element is continuing the memory of the school as well, at the same time, it is the respect to life.

作为整个花园最重要元素的树桌，看似自由随机的外型，实际上也是分析推导出的。规模按照一个40人班级的课桌尺度演变而来；定位依照树干点位环绕放置；间距与空隙则与周边建筑接口与通道对接。

Tree desk, the most important element of the whole garden, seems to be with free and random appearance, actually, the appearance is gained after analysis. The scale is evolved in accordance with the measure of the desk of the class with 40 students. And the positioning is placed by surrounding the point positions of the trunk; The spacing and interspace are in accordance with the aisles of the surrounding buildings.

树桌花园带来了SES第一处室外的非正式学习空间。与室内或半室内空间比起来，这里拥有更开放的环境氛围，有更便捷的步行体验和更绿色的自然景观。树桌花园鼓励老师和学生们的自由使用，拓展出原有庭院所不具备的功能。

Tree Desk Garden brings the first informal outdoor learning space in SES. Compared with indoor and semi-indoor space, the garden owns a more open ambience, which will bring more convenient walking experience and more green natural landscape. It is encouraged that the teachers and students should freely use the Tree Desk Garden to expand the functions which has not been equipped by the original yard.

在平常时分，树桌花园对SES来说是一片绿色的充满诗意的存在，安静地陪伴着老师和学生们，当各种活动融入，这里瞬间成为充满活力的校园中心。树桌花园没有围栏，没有出入口，没有固定的座位，也没有繁琐的使用规则，有的只是尺度适宜的台面和平整的场地空间，鼓励各种充满想象力的多样化使用。

At the usual time, Tree Desk Garden is a poetic green land for SES, it quietly accompanies with the teachers and students. When blending in various activities, it becomes the center of the campus full of energy in a moment. The Tree Desk Garden is without handrail, no entrance, not fixed seat or fussy using rules, but console surface with appropriate scale and floor space with flat surface, and here, the diversified use full of imagination is encouraged.

和雨水花园类似，除了保留所有原生树外，树桌花园也采用了全透水地面的生态设计，雨水可以全部渗入地下，同时也减少地面湿滑。考虑到建筑内外平接的地坪，为防止暴雨期间雨水倒灌入室内，全区采用了线形排水系统。对比2015的庭院和2018的树桌花园，上层的绿化覆盖几乎一样，甚至更茂盛了些。然而下层空间却由缺少互动的图案型绿地转换为充满活力的友好型空间。其中的改与不改，变与不变，很好地传递处出空间有机更新的要义。

Similar with Rain Flower Garden, except for serving all the native tree, the Tree Desk Garden also uses the eco design of permeable ground, all the rain can permeate into the ground and the slip and wetness of the ground can be reduced at the same time. Considering that the grade level connected by the buildings outside, and preventing from the rainwater flowing backward to the inside of the building during the rainstorm, the linear drainage system is used in the whole area. Compared with the Tree Desk Garden in 2018 with the yard in 2015, the green covers in the upper layer are almost the same, and even more flourish. While the lower space has been transferred into friendly space with energy from the pattern type green space lacking of interaction. The things which have been changed and which have not been changed well transmit the substance of organic renewal in the space.
