KH studio给gooood分享了他们最近赢得的COLUMBUS QUARTIER国际竞赛头奖作品“Hybrid Landscape”。这是一个城市入户交通区域的整体形象改造项目，总规由MVRDV和Francis Kéré领衔。KH_studio提出混合风景理念。希望将这片位于开阔绿地中的繁忙交通区激发成为一个富有活力的平台区域。
KH_studio has just won the first prize at the international restrained competition for COLUMBUS QUARTIER in Mannheim (DE).
As a following of KH’s MANNHEIM’S CONNECTION, the Europan winning proposal for B38 highway city entrance and its urban sector of 250 Ha, Ilaria Novielli and Alessandro delli Ponti were invited to a restrained competition against 12 international firms, going from Rudy Ricciotti to AGPS, Ortner-Ortner, Baumschlager-Eberle or Motorplan. It was an extremely hard task, as stated by city representatives in the recent press Conference, but KH’s proposal made the unanimity of the jury. The winning proposal is based on a strategic approach merging mobility with programmatic and landscape issues in a time sequenced development. KH’s masterplan will integrate a metropolitan sector with nearby urban schemes by MVRDV and Francis Kéré.
The international competition asked to imagine Columbus Quartier as the new main entrance to the city of Mannheim (DE), the reshaping of B38 highway (already treated in EUROPAN 12 Competition) demanded the transformation of a 35 Ha linear area of formerUS military basis which are the scene of action of the “Hybrid Landscape” project by KH_studio.
Hybrid Landscape – exploring infrastructural porosity
Set in between a wide green campus and a heavy highway infrastructure, Columbus Quarter is
conceived as a hybrid landscape, which can be activated starting tomorrow.
Its generous space, and its military palimpsest is capable to host a vast variety of vocations and
programs, going from commercial functions to offices or university spaces. The challenge is thus that
of building an adaptable coherence through time, answering positively to diverse issues coming from
different actors and taking the best out of each to build a strong and dynamic identity for Columbus.
The relational strategy which founds the project orients short term demands on long term ambitions,
allowing to define an original but credible hybrid quarter for the city of Mannheim.
The progressive development of built areas and of landscape are merged through time, in order to
assure an new strong image to the entire sector.
The DNA of the project imagines its transformation through its different ages, from immediate
activation to the adaptation to a real post-car city configuration. This strategic DNA is set in some key
guiding concepts: mobility differentiation, spatial porosity, environmental and mobility infrastructure
hybridation, environmental activation of built units, phased program articulation.
The project becomes an active platform to build an actor-relational optimised strategy through time.
设计师希望将各种功能：商业，办公，学校等都汇聚在这片承载交通压力的大绿地之中。并改善各区
面目最终建立起整个区域强有力的形象。设置循环通道联系各个内置功能块，在绿色场地中连续布置
袋装的空间和见缝插针的小空间，实现主动空间利用率，支持体育活动比如滑板等等活动。
针对公路，设计师希望把公路变成一条美丽的林荫大道，停车场变成绿地与公路间的缓冲区域。在停
车场布置植草景观，低矮的农业景观。积极利用建筑屋顶和墙面的太阳能电池产生能源，为区域公共
照明以及微小电动车提供充电，降低能耗。将道路分级，设置直接能到达写字楼的电车道和自行车道。
写字楼区域的停车场到了晚上可变成绿色休息空间或者体育运动空间。在整个区域中布置雨水收集系
统利用中水，实现绿化灌溉自足。
整个园区，学校与商业混合成为一个交通便利，可持续性，可发展式的校园商业景观。

Hybrid 1 - Green Arcipelago and the active strip
At the scale of our site Birkenauer stra?e is part of a loop traversing and connecting a built
archipelago. In continuity with the inherited plot system, along Birkenauer stra?e, green transversal
pockets structure its porosity.
From day one Birkenauer will be the scene of micro actions on the site, from temporary pop-up
programs, linked to the launching of programs and participatory initiatives, to informal landscape
operations that can be allowed on the strip, in possible coordination with the BUGA initiative.
Progressively, with new program implantation, Birkenauerstrasse becomes animated, on the campus
side, by intense ground sport programs and singular qualitative volumes, gliding on the free landscape,
and densifiyng around the Friendship circle’s were the different spatial values of the project meet.
Hybrid 2 – Next generation highway
B38 can be reconfigured starting tomorrow. The mobility analysis of car flux shows that it would be
easy to reserve the right lane to serve new programs on the side of B38. This would be the first step
to transform the current hard infrastructure into a boulevard, without yet launching a heavy
investment. B38 is thought as an hybrid boulevard, giving major investors visibility while turning
dimensional constraints in active devices for the environmental qualification of the whole area. The
setting of the major investors is strategic. Mono-specialized commercial volumes and their parking
areas define a landscaped buffer protection for the entire site from day one, but also allow future
transformations to both program and parking plots when B38 will become a slow boulevard.
Parking lots are thought as agronomic landscapes, and disposed in order to allow potential
mutualisation with other programs. South double facades and terraces become effective means to
regulate heat and cold while producing solar energy. The built pochets as the landscaped ones produce
a transversal coherent approach for the entire site.
DNA - key strategies :
Mobility differentiation
B38’s reserved right lane only serves retail, avoiding heavy traffic on Birkenauer strasse.
The slow mobility commercial venue and quarter loop is directly connected to the tram, it also hosts
electric bus and bike passage on a free surface system.
Birkenauer, serving as tram lane, hosts bike paths and gives direct accessibility to newly built office
programs.
Multimodal spots assure connection with the overall city system.
Active mutualizations
Mutualization is a basic principle, applied to different topics.
Retail parking lots can become accessible at night for programs set in green pockets or in sports areas.
Rain water an used water is recycled and treated in order to be used for public space mantainance and
building functionality (gray waters). In the mean while wast humid areas in green pockets can host
water treatment. Electric energy produced by the quarters active roofs and facades is re-immitted in
the system or directly linked to public illumination system or light vehicles recharging, making the
sector autonomous.
Hybrid program
Macro retail volumes structure the b38 landscaped fa?ade, but they are set in a stimulating urban
relation with green areas and other programs, contributing to define an hybrid commercial park,
where, from university to company, passing through start-up and co-working all the phases of a
company formation and all the scales of commercial activity can be effectively represented.
Environmental Porosity - activation of built units
Porosity to rain water and sun sculpts the volumetric setting of the plot. South facades are used to
regulate climate and produce energy. A high permeable ratio is assured both in built units as in public
spaces, allowing reusing rain water for grey water in buildings and landscape maintenance.
Hybrid landscapes
Green reserved areas are a landscape progression moving from hard infrastructure to campus,
merging the two faces of Columbus Quartier. They are thus thought as hybrid “serving landscapes”
with a key role in the strategic functioning of the area. They assure a green buffer zone on B38 and
help collect rain water for the quarter, most of all they host informal uses and evolve and densify
throught time in parallel with built plots densification.
