Sustainable development should take into account the conservation and preservation of architectural features characteristic of a given cultural area for future generations. Chemical, physical and mechanical properties of timber components are key to assessing the technical preservation of historical timber structures, defining proper restoration methodology and extending the durability of timber structures. Moreover, this evaluation will help to elaborate assessment criteria to decide between the restoration or replacement of a given antique structure. The article presents a method of assessing a historical wooden structure on the example of an antique decorative wooden floor from the beginning of the 19th century, preserved in the Tarnowiec Manor House. It determines tests and scientific analysis as a tool for a decision of possibilities of further usage of the historical floor structure. We performed tests and scientific analysis by calculating the functional properties of the parquet panels, performing a visual inspection, as well as resistance tests, tests of longitudinal curvature deviation and shape preservation, tests of fungi infestation and its impact on the state of preservation, as well as future perspectives for the use of parquet elements. The results of the evaluation verify that the proposed methodologies are reasonable and will help to elaborate assessment criteria to decide between the restoration or replacement of a given antique parquet.
