This repository contains a collection of data on 99 contemporary multi-storey timber building projects in the DACH region (Germany, Austria, and Switzerland), designed and planned between 2004 and 2021, and the stakeholders involved in their design and construction. The dataset consists of quantitative and qualitative project data on buildings 4 stories tall and above. This includes general information on project location, construction year, building height (number of stories), links, type of structural system, materials used in construction, and classification of the design based on the form of the massing and the organization principle of the floorplan, as well as a classification into innovation trajectories in timber construction. These are defined as the following three groups; (T1) standard innovation, (T2) incremental innovation, and (T3) pioneering innovation trajectories in timber construction. A total of 306 project stakeholders, their roles on the project as architects, engineers, timber engineers, general contractors, fabricators, and timber suppliers, the client type (public or private) and, when available, the motivation for the use of timber (i.e., sustainability) are also included in the dataset. Link to their website, and location absed on the headquarters, are included in the data on the stakeholders. In addition, the buildings data includes projectID's that can be used to find the projects in some of the related datasets.
