重庆是一座生长在山脊之间的城市，在对山地的适应和利用中，当地人与自然的关系达到一种共存的平衡，形成如今具有地域特色的城市景观和生活方式。大小景观为重庆龙湖昱湖壹号设计的社区景观，以一套基于场地的设计策略，延续了这一智慧。

Chongqing is a city born in the mountains. People in Chongqing have developed their own way of using lands with topography, and have created unique urban landscape and lifestyle. Atelier Scale has carried and extended this wisdom, in the landscape of the Hill Residence (named as the Ｗaterfront City by the developer), developed by Chongqing Longfor.

Return of the Hill

项目所在地有一座现存的山体，按原建筑规划，红线内的一段山脊将被铲平，沿红线将出现一段最高达16.5米的挡土墙。大小景观希望恢复这条被切断的山脊，并以此为空间框架构建户外活动场所，为居民带回自然体验，营造开放友好的社区氛围。

There is an existing hill located in the project site. The original master plan by architects causes great damage to the natural topography of the site. Part of the hill will be completely leveled with a vertical retaining wall of 16.5 meter high, separating the other part of the hill and the site. Atelier Scale proposes a smoother transition from the hill to the site: 1. Regrade the site in order to follow existing ridge topography; 2. Restore an accessible connection between the site and adjacent nature; 3. Turn the returned hill into a community living room and other part of the hill into a public park.

The Hill Residence occupies total area of 10.7ha, as large as the Bijin Park in Chongqing (13ha). The ridge corridor connecting the hill and community has a lenth of 170 m and a width of 40 m. It works as connecting path as well as a micro eco-corridor. The micro biotope in the seasonal creek and metasequoia along the hill trail serve as the Stepping Stones for birds and amphibian.

Stormwater Management System

场地内的地形变化为搭建雨水回用系统提供了条件，景观通过对全区竖向关系的梳理，组织地表径流，引入季节性溪流（120米）/集中式雨水花园(200㎡)/透水铺装／生态草沟等海绵城市设施，实现场地内雨水收集-调蓄-净化-回用循环系统，径流总量控制率达70％; 同时, 通过景观设计手法，将这一生态过程可视化，与活动空间相结合，面向居民开放，成为接触自然，观察雨水净化过程的科普性景观节点。

based on a newly graded site topography, we are able to create a more sustainable storm water management system, which organizes storm water runoff effectively, reduces the flood pressure, and reuse water smartly. With collaboration of a storm water management expert in Seattle, we have come up with two main strategies to collect rainwater runoff: 1. The sloped seasonal creek beneath the elevated trail collects rainwater from the hill, which will be guided to the rain garden in the middle of the community; 2. Series of bio-swale network in front of unit entries guides rain water into the rain garden. Besides high-performance function, the storm water management system works as educational landscape, which provides residents opportunities to learn about how this natural system work. Educational illustration points are designed to integrate with this system, making sure the landscape will be understood by residents especially children. Water after purification is stored in a central water tank for reuse, such as water feature and kids wading pool. Besides, 50% hard surface of the site are permeable pavers including pourable concrete, pourable brick and gravel.

山脊社区的设计美学并不是先入为主的，场地之字形的设计语言，来源于在变化的高差中创造无障碍通行的需求，这样的语言也顺势成为了从小到家具、大到地景的系列语汇。在语言统一的前提下，设计回归场地，根据竖向和空间尺度做出具体的语言决策。

The design language is innovatively found instead of created, by previous research and study. 1. Zig-zaging trails are designed to achieve slope-friendly accessibility; 2. Ridge decks are created for amphitheater and reading gardens with integration of planting terrace; 3. A bridge cross is created based on site topographic change for overlook above and shaded recreation beneath; 4. Topography between buildings is preserved with designed seat terrace and bar table; 5. A playground is sided by a sloped creek with water interactions. Through introducing these designed spaces and local way of life, a new balance between the hill and community can be reached.

Summary

山脊社区的设计与实践，一如既往地延续了我们对项目在地性与生活方式的思考。同时，我们开始关注居住区对城市环境的影响与贡献。目前山脊社区已投入使用，我们将持续关注居民对社区空间的使用体验，以及社区自然环境的生态绩效。

The design and practice of the Hill Residence continue our thinking on locality and lifestyle of residential neighborhood, at the meantime, we begin to focus more on the contribution and impact of residential communities to urban ecology. As the Hill Residence being used by residents in the future, we will be paying more attention to the usage of space and ecological performance of the community, with the help of POE.
