Wooden materials are regaining popularity in building construction, and therefore maintaining buildings with wooden elements is increasing significance. A sustainable approach expects prolonged use of already constructed buildings to reduce the demand for building materials. Maintenance periods are calculated for up to 50 years and more. Therefore, material aspects are needed to be identified and considered for the planning of renovations and repairs. Current research aims to evaluate building management aspects of hybrid timber buildings. Research methods applied to this study are literature review, technical solution analysis and case study analysis. Results show that primary concerns for wooden construction maintenance is moisture protection as prolonged exposition to moisture are deteriorating timber construction elements. Increased moisture levels also provide an environment for mold or other “illnesses” of timber elements, especially in connection points, where timber elements are used together with steel or concrete. Conclusions reveal that maintenance of hybrid engineered timber buildings should be performed within the framework of regular maintenance processes considering the specifics of timber elements.
