项目陈述
Project Statement

这片生态敏感地带的全方位修复工作，包括保护一段中西部冰川湖泊的独特湖岸线，确保了一个家庭度假地的永续传承。在挽救这片壮丽却严重退化的土地时，景观设计师提出了一项充满潜力的解决方案，其愿景在于通过挖掘景观的细微之美，展现场地的真实与纯粹，成为基于保护、管理和可持续生态适应的设计典范。设计方案充分借鉴了丰富的地质背景，通过运用强有力的生态修复技术与精心打造的户外空间，创造出一个层次分明的景观，展现人与自然和谐共生的可能性。

The holistic rehabilitation of an ecologically sensitive landscape, including protecting a unique shoreline along a midwestern glacial lake, ensures the enduring legacy of a family retreat. Brokering a potent solution for a majestic but highly degraded property, the landscape architect created a vision that incorporates the subtleties of the landscape to reflect the sincerity of the locale and serve as a model for design with an action plan based on conservation, stewardship, and sustainable ecological adaptation. Incorporating cues from the rich geologic subtext, the plan reflects the application of vigorous ecological restorative techniques with crafted outdoor spaces resulting in a layered landscape that builds upon its environment.

Project Narrative

历史背景

坐拥由冰川雕琢而成的湖泊纯净水域，这片占地1.7英亩的土地曾因数十年高强度的人为干预而逐渐失去生态价值，原本丰富的自然景观几乎荡然无存。场地内散布着多处建筑、大片草坪以及包裹树木根部的沥青覆盖区，加之由外来物种构成的不稳定且具有侵蚀性的湖岸线，场地亟需重新规划与管理。浓密的外来树种形成了层层叠叠的厚重树冠，妨害了下层植被的生长，这使沉积物和化学物质从周边土地直接流入了湖泊，进一步破坏了生态系统。

然而，即便景观退化严重，零星的白橡树依然矗立其中，唤起了曾经遍布这片区域的橡树林草原的记忆——一种如今罕见而珍贵的生态景观，令人不禁追忆那片曾经广袤而生机勃勃的土地。

设计愿景

客户希望通过修复这片生态敏感的土地，在重建夏日湖畔生活传统的同时，打造一个示范性的土地管理模型，为环境友好实践提供灵感与借鉴。

过程

设计团队深入研究草原与林地的自然关系，认识到它们之间蕴藏着丰富的栖息地类型和多样化的树冠覆盖特性。通过对场地进行全面的横断面分析，设计团队初步勾勒出树冠闭合度和排水模式的分布情况，从而定义了三个核心景观区域：草原、开放林地和密林。随后，设计团队果断移除了所有外来物种，将硬化道路面积减少40%，并用20余种草本植物、莎草和90种野花替代了35,000平方英尺的草坪。

在湖岸区域，设计团队种植了根系深厚的乡土植物，用于稳固陡峭的湖岸（坡比打到1.5:1），同时引入湿地植物形成天然缓冲带，有效提升水质并显著增加生物多样性。这种恢复自然平衡的方法挑战了现行法规偏重砖石结构的传统治理方式，避免了湖岸被人为硬化和单一化的处理，重新赋予湖岸其原有的自然之美与生态功能。

应对气候变化

在这一气候变化影响显著的区域，森林结构的转变、极端温度波动、湖面高度起伏等问题不断显现，而栖息地的退化和原生植物群落的破碎则尤为严峻。为阻止树种组成的进一步单一化，设计团队制定了一项全面的植被演替计划，通过引入多样化树种来保护现有森林，同时抵御虫害、病害、土壤压实、干旱及洪水带来的威胁。与此同时，本地草原物种通过稳固土壤、防止养分流失、吸收雨水、过滤污染物，并吸引丰富的传粉者、鸟类及其他野生动物，为场地的生态韧性提供了重要支持。这些措施不仅遏制了气候变化的负面影响，也为整个区域注入了新的生命力。

与自然共处

住宅以外展的L形布局，与湖泊和场地北侧边界和谐相融，而重新设计的车行道优雅地沿场地东侧环绕延伸。通过将建筑与功能区布局于场地边缘，设计重新恢复了草原景观的开阔感与历史上的排水路径，既提升了从公共视野欣赏的景观品质，也为到访者营造出沉浸式的入口体验。走在雕塑般的橡树间，住宅建筑宛若自然生长于缓缓起伏的地形之中。从道路望去，住宅隐匿于树影中，流露出一种低调的优雅；而从湖泊望去，建筑则呈现简洁的单层形式，与周围环境浑然一体。住宅的绿色屋顶面积达2,500平方英尺，仿佛草原的延续，从空中俯瞰更是一幅自然与建筑完美交融的画卷。共享的户外空间为不同年龄段的人们提供了既能休闲娱乐又能亲近自然的场所。低矮的独立墙体巧妙地划分出空间边界，而蜿蜒的透水步道轻盈地穿梭于景观之间，勾勒出场地动静结合的生动画面，也让人深刻感受到这片土地所蕴含的动态生命力。

Project Narrative

CONTEXT

Overlooking pristine waters of a glacially-formed lake, the 1.7-acre property sustained decades of intense human intervention, diminishing its ecological value and denuding the native landscape. Multiple structures, large expanses of lawn, and tree-girdling asphalt extents combined with unstable and eroded shoreline comprised of non-native species, demonstrated the need for a renewed commitment to proper land management. A dense and competing canopy of non-native trees overwhelmed visible signs of understory growth, allowing sediment and chemicals from adjacent properties to drain into the lake. Degraded conditions aside, stands of burr oaks punctuate the land, recalling the once dominant oak savannas that proliferated across the region, but are rarely seen today.

VISION

With a desire to recreate a summer lakehouse tradition, our clients sought to create a transferable model for stewardship through restoration and environmentally progressive practices.

PROCESS

Understanding that a savanna possesses a wide range of habitats and canopy coverage, the team created a transect of the property, analyzing canopy closure and drainage patterns to define three distinct landscapes: prairie, open woodland, and woodland. Next, the design removed all non-native species, reduced vehicular paved areas by 40%, and replaced 35,000 square feet of lawn with over twenty varieties of grasses and sedges, and ninety species of wildflowers. Lakeside, native plants with root systems predisposed to providing natural erosion control stabilized the extreme 1.5:1 slope while wetland plugs offer a riparian buffer, improving water quality and biodiversity. This approach challenged existing regulations that proposed masonry-based solutions – a common approach that had armored and individualized the once-natural bank.

COMBATTING EFFECTS OF CLIMATE CHANGE

In a region where climate change and human land use has been at the center of shifting forest compositions, temperature swings, lake level fluctuations, and other habitat irregularities, the decline and fragmentation of native plant communities and protective growth habits is obvious, particularly in the deterioration of habitat. To prevent further homogeneity in tree species composition, the team implemented a succession plan with a diversity of species that protects the existing forest and counteracts the susceptibilities introduced by insects, disease, soil compaction, drought, and flooding. Native prairie species help buffer soil and nutrient loss, absorb rainwater while filtering toxins, and attract a wide variety of pollinators, birds, and other wildlife.

COMMUNE WITH NATURE

The splayed, L-shaped footprint of the home parallels the lake and northern boundary, while a reconfigured driveway skirts the property’s eastern edge. By gravitating the program to the perimeter, the plan reestablishes an expansive prairie landscape and its historic drainage-ways, elevating scenic quality from public rights-of-way and creating an immersive entry experience. Nestled within sculptural oaks, the home emerges from a gently sloping landform when viewed from the road, while reading as a single-story structure from the lake. A 2,500 square foot green roof appears as a lifted extension of the prairie. Shared outdoor spaces unite generations for recreation and communion with nature. Low, freestanding walls denote thresholds while permeable pathways sinuously link amenities and emphasize the dynamism of the landscape.
