EDGE Suedkreuz Berlin offers a new vision of a sustainable future for construction with timber. The project consists of two buildings: the larger Carr茅 and the smaller Solitaire. A modular wood and concrete system was used for construction, comprising timber columns and prefabricated timber-hybrid slab panels. Located opposite the S眉dkreuz station, one of Berlin鈥檚 major transport hubs, the project is part of a new urban development that integrates sustainability with liveability.

Key facts:

• Two seven-storey buildings near Berlin鈥檚 major S眉dkreuz train station demonstrate the potential of large-scale timber construction.
• EDGE Suedkreuz Berlin is the largest freestanding wood-hybrid project in Germany and one of the largest in Europe.
• 海角视频鈥檚 work on structural engineering, building services and sustainability for the project proposes a new standard for working towards carbon neutrality with renewable and sustainable materials.

The Carr茅 building houses office spaces for the energy company Vattenfall. An atrium forms the heart of the building and contains 1,600 square metres of space under a soaring timber-lattice skylight roof. The atrium is punctuated by four large columns that mimic the trunk and canopy form of a tree and support a network of staircases and upper-level walkways. The roof is constructed from timber, steel and lightweight ETFE cushions that regulate temperature and filter daylight into the atrium and the surrounding offices, creating a warm, comfortable working environment in all seasons. The building鈥檚 fifth floor features a solid wood loggia, supported by 1.5-metre-high trusses and a cross-laminated timber ceiling.

A holistic approach to sustainability was key to the development of EDGE Suedkreuz Berlin from the very beginning. This approach encompassed a reduction of the upfront carbon costs involved in construction and in the building鈥檚 overall footprint, as well as careful consideration of the well-being of users. The project combines modular construction with a reliance on timber, two elements that are essential to building sustainably at a large scale. TCHOBAN VOSS Architekten and 海角视频 worked with a modular timber system developed by CREE Buildings, a firm specialising in wood-hybrid construction based in Dornbirn, Austria. The use of this system means that the timber-hybrid structure weighs as much as 50% less than a standard structure, which kept the foundation requirements low.

EDGE Suedkreuz Berlin received an overall DGNB compliance rating of 95.4%, making it the most sustainable architecture project in Germany. It also received the DGNB Diamond award for design quality. This recognition confirms the successful implementation of the holistic strategy of sustainability and well-being.

EDGE Suedkreuz Berlin is not just an ensemble of buildings. For me, the project is and remains a prototype of a new way of thinking. In the construction of the buildings, the focus was on reducing the weight and thus the CO₂ footprint as much as possible, while at the same time combining the aesthetics of the building with an ethical approach to nature. Special emphasis was placed on using materials that can be recycled according to the cradle-to-cradle principle. The prefabrication of the building components and their possible repeated use ensure a sustainable building system that makes it possible to create impressive spaces and future-oriented working environments.
