Dataset of Structural and Material Systems across 240 Multi-Storey Timber Buildings: Four-Level Classification of Building Volume, Building Systems, Decks, and Connections, with Timber Use Level

Name, ID, City, Country, Architect, Year, ConstructionStatus, Program, ProgramSubtype), building scale (numberOfStories, numberOfWoodStories), and references to source material (Links). The dataset classifies buildings according to their structural and material systems at multiple levels, including structural type (ST_Type, ST_SubType), building volume-level material composition (MT_BldgLevel) with podium and core materials (MT_podium, MT_core), building systems (MT_VerticalSystem, MT_LateralSystem, MT_HorizontalSystem), deck systems, connection approaches (MT_ConnectionLevel), secondary materials, composite elements, and overall building system configurations.

Each project is also assigned a relative timber use level (TimberUseLevel) and a DataConfidence rating. File project_summary.csv provides complementary metadata for the same set of buildings. It includes standardized country identifiers (Country ISO 3166-1 alpha-2), a subset of key classification variables for reference such as name, year/status, storeys and location, summary of classification at each analytical level, and indicators for the availability of different source materials, including material axonometric drawings (SRC_Mt-Axon), construction photographs (SRC_C-Photos), videos (SRC_C-Video), detail drawings (SRC_Detail), reports or scientific papers (SRC_Report/Paper), books (SRC_Books), primary source status (SRC_primary_list), and source links (Sources/Links).

This file facilitates filtering projects according to the available documentation and supporting evidence. The dataset is intended for comparative analysis of structural typologies, material systems, deck assemblies, connection approaches, timber utilization, and documentation availability in contemporary multi-storey timber buildings. A detailed description of the classification categories and their scope at each level is provided in the related publication.

The project_summary.csv file is also published as a supplementary table in the related publication.
