EDGE Suedkreuz Berlin offers a new vision of a sustainable future for construction with timber. The project consists of two buildings: the larger Carré and the smaller Solitaire.
A modular wood and concrete system was used for construction, comprising timber columns and prefabricated timberhybrid slab panels.
Located opposite the Südkreuz station, one of Berlin’s major transport hubs, the project is part of a new urban development that integrates sustainability with livability. The Carré 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’s 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’s overall footprint, as well as careful consideration of the wellbeing 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 Buro Happold worked with a modular timber system developed by CREE Buildings, a firm specializing 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.
“The modular timber construction of EDGE Suedkreuz Berlin radically reduces the amount of concrete necessary for structural support and offers a viable, scalable alternative for building sustainably. The project demonstrates one of various possible responses for the AEC industry to climate emergency” says Martin Elze, Associate Director, Buro Happold.
