架构师提供的文本描述。R50-合建公司是柏林-克鲁茨堡的一个合资建筑项目。这是建筑师在建筑地块的概念授标过程中发起的，并与客户密切合作实施。建筑方案是建立在一个明确的城市设计立场，稳健和精确的建筑设计，以及一个集体和个人的占用过程。

Text description provided by the architects. R50 – cohousing is a joint building venture project in Berlin-Kreuzberg. It was initiated by the architects during the course of a concept-based award procedure for building plots and implemented in close cooperation with the clients. The building proposal is founded on a clear urban design position, robust and precisely detailed architectural design, and both a collective and individual process of occupancy.

这座独立的建筑被战后柏林所特有的各种住房概念所包围.它有六层整层，一个地下室和一个阁楼。它包括三个街区，19个单独的公寓，一个工作室和各种共享空间。下面是一个双高的、灵活的社区空间，它将建筑物的主要通道与公共街道空间连接起来。它提供给邻里团体和其他公共用途。钢筋混凝土结构设计达到最低要求。结合减少和部分暴露的基础设施，模块化木材立面与固定和灵活的，向外开放的玻璃门元件是专门为这座建筑开发的。这与每一层的全方位阳台结合在一起，使建筑物的建筑与其使用之间进行了直接的对话。

The detached building is surrounded by various housing concepts characteristic of Berlin’s post-war period. It has six full storeys, a basement and an attic. It comprises three blocks with 19 individual apartments, one studio and various shared spaces. Underneath is a doubleheight, flexible community space which connects the building’s main access with the public street space. It is made available for neighbourhood groups and other public uses. The reinforced concrete structure was designed to minimum requirements. Combined with the reduced and partly exposed infrastructure, the modular timber facade with fixed and flexible, outward opening glazed door elements was specifically developed for this building. This combined with the all-around balconies on each level allows a direct dialogue between the building’s architecture and its use.

满足业主的集体和负担得起的生活和工作的愿望，建筑概念是建立在一个紧凑和有效的结构，仔细细致的连接在不同的规模。它的基础是一个混凝土骨架，有一个通道和两个服务核心，一个独立的木材立面和悬吊钢结构为四周阳台。一个稍微凹陷的地下室层提供进入建筑物和合并私人和公共空间。每套公寓和所有额外的社区空间都是通过密集的协商、讨论和设计过程开发的。根据结构框架，可以确定公寓的大小，并在楼面平面图中满足个别要求。在这一过程的同时，制定并确定了固定装置和配件的共同标准，这导致了对室内配件的集体处理，对材料和一些表面的使用仍未完成，同时允许公寓的个别布局。这种结构化而开放的设计过程不仅允许了广泛的参与、自主设计和自我建造，而且在居民共享的空间类型、位置、大小和设计上也达成了共识。这其中包括慷慨的城市花园，它自然融入了60年代周边住宅区的景观，一个通往地下室前面有盖区域的通道坡道，一个洗衣房，一个车间和一个屋顶露台，有一个夏季厨房和一个冬季花园。四通八达的阳台伴随着明亮的室内空间，连接着每一层的公寓。

Meeting the owners’ aspiration for collective and affordable living and working, the architectural concept is based on a compact and efficient structure with carefully detailed connections on different scales. It is based on a concrete skeleton with one access and two service cores, an independent timber facade and a suspended steel construction for the all around balconies. A slightly sunken basement level provides access to the building and merges private and public spaces. Each apartment and all additional community spaces were developed by an intensive process of consultations, discussions and design. Based on the structural framework the sizes of apartments could be determined and individual requirements accommodated in the floor plans. In parallel to this process, a common standard for fixtures and fittings was developed and defined, which has resulted in a collective approach to interior fittings, the use of materials and some surfaces left unfinished, whilst allowing individual layouts of the apartments. This kind of structured yet open design process has not only allowed for extensive participation, self-directed design and self-building, but has also led to mutual agreement on the type, location, size and design of spaces shared by residents. This includes the generous urban garden, which naturally blends into the landscape of the surrounding 1960s residential neighbourhood, an access ramp leading to a covered area in front of the basement, a laundry, a workshop and a roof terrace with a summer kitchen and a winter garden. The allaround balconies accompany the bright interior spaces and connect the apartments on each floor.

R50-合住是一种新的模式类型的低成本和负担得起的住房，提供了最大的适应能力和灵活性，在其整个生命。社会、文化、经济和生态方面也被同等考虑，以确定当代城市生活的可持续办法。德国节能法规(Enev 2009)规定的限值降低了30%。可持续性的另一个基本方面是建筑融入现有城市结构的特殊能力。

R50 – cohousing is a new model typology for low-cost and affordable housing offering a maximum capacity for adaptation and flexibility throughout its lifetime. Social, cultural, economic and ecological aspects have been considered equally to define a contemporary sustainable approach to urban living. The limit set by German Energy Saving Regulations (EnEV 2009) was reduced by 30%. Another essential aspect of sustainability is the building’s particular ability to integrate into the existing urban fabric.
