After numerous realizations in small-volume timber construction and an intensive occupation with multi-storey urban timber construction within the framework of the research project Eightplus, Schluder Architektur was in charge of the first seven-storey residential building in timber construction in Austria. With the construction on Wagramer Straße, Schluder architectural office and its project partners proved that wood is not only an excellent building material due to its ecological and sustainable qualities as a CO2-neutral building material and its often praised positive effects on living comfort and room climate, but also justifies its use in terms of construction economy and constructive properties.

The six upper floors of building component A were erected in a solid wood construction made of cross laminated timber. The prefabrication of the wall and ceiling elements, including all openings, not only accelerated the completion of the shell, but also guaranteed a cleaner construction site than with conventional construction methods and thus healthier working conditions. The timber construction is mineral clad, i.e. plastered on the façade and planked with drywall on the inside, which eliminates the risk of the timber components being ignited. The ground floor is made of reinforced concrete - as prescribed by the Viennese building regulations for timber buildings with four or more storeys - as are the three staircase cores for the purpose of overall reinforcement and the transfer of building loads.

The complex consists of a seven-storey structure on Wagramer Strasse (component A, Schluder Architektur). Attached to this structure are three lower, three-storey blocks (building component B, Hagmüller Architekten), which form a kind of transition to the lighter and looser building structures in the surrounding area. Each apartment unit has a private open space in the form of a loggia, balcony or terrace. The ground floor houses the communal facilities and a guest apartment. A total of 2,400 m³ of cross laminated timber was used in the project. Approx. 2,400 tons of C02 are stored in it. If the building is dismantled at the end of its service life, the approximately 19 terajoules (approx. 5.2 TWh) of stored energy can be used and converted into electricity and heat. This means that the building material wood alone saves fossil energy in significant quantities through renewable raw materials available in Austria. This innovative residential building has been awarded the first prize in the developer’s competition "Holzbau in der Stadt" ("Urban Timber Construction") and represents a model project that makes an important contribution to the further development of sustainable construction methods in residential building
