Holzriegel Hof

Upgrading existing buildings with timber construction

he Holzriegel Hof builds on the existing underground car park, closing the edge of the block with a five-storey development along the entire length of Inzersdorferstrasse and thus creating a large, green, shared inner courtyard as added value for the existing building. The flats are accessed via a reinforced concrete pergola on the courtyard side. In front of the pergola are three free-standing structures with additional small residential units. Commercial uses are located in the plinth on the street side, while common rooms are arranged on the courtyard side. The design of the façades also differentiates between the street and courtyard sides: the street façade has a reddish colour scheme based on the neighbouring brick building and thus blends in well with the streetscape. The buildings on the courtyard side are colourful and enliven the overall appearance. The new building is designed as a solid timber construction with a timber-clay ceiling above the ground floor. The construction of cross-laminated timber walls and ceilings and timber frame walls for the exterior walls is designed to be recyclable, glue-free and demountable. The project impresses with its unagitated approach, while respecting, enhancing and upgrading the existing building, as well as the well-thought-out concept and elaboration of the timber construction, clearly utilising the strengths of timber construction.
