The purpose of this study is to explore and explain concepts, processes and resources associated with the practical renovation of a privately-owned wooden house and make recommendations for future best practices in such renovation. The methodology consisted of observation, interviews, and document analysis. The research found that the “practical ecological renovation” of the wooden house emerged from an experienced architect working under time, cost and the availability of material limitations. The concept is not to freeze the architecture, but to transfer cultural significance of the place and to accept certain changes. Accordingly, minimal intervention is desirable in making the house livable. From an ecological approach, natural aspects and traditional knowledge of craftsmanship from previous generations are outlined in this study. A non-linear and improvisational conservation occurred due to the project limitations. Ultimately, five dimensions have been identified in relation to the renovation of privately-owned houses, which are: nature and its essence; the balance between the owner’s requirements and the architect’s values; a network of craftspeople; craftsmanship and appropriate materials and technologies. However, these five emerging results are interrelated and inseparable. From a practical view, the wooden conservation is not only the preservation of physical fabrics, but it relates to other dimensions, including preservation of traditional knowledge and design techniques.
