There is a growing demand on using log as a construction material. In addition, production technology and technical properties of log products have undergone rapid changes in the era of industrial production. Examples for use of industrial log, that are architecturally suitable for the requirements of new uses, are few. For these reasons in this paper, it is explored what are the properties of industrial log building, and what kind of novel, structurally characteristic architectonic solutions for industrial log emerge in contemporary architecture. Besides a literature review, a qualitative analysis on five examples of contemporary architecture is conducted. As results, we showcase several novel architectonic solutions for industrial log. The first category of results, overall configuration of logs, includes entireties of logs that are structurally bearing, but also entireties where the logs act in other function than as structurally bearing. Entireties of logs are supported by next two categories – joining of logs and properties of individual logs, which can both be seen as components of the overall configuration. This study creates basis for further research on architectural possibilities of industrial logs. In addition, findings of this research can serve as an inspiration for designing architects and log house industry.

Only a few percent of new detached houses in Finland are designed by architects. Most people planning to build a house use only free design services included in the price of house delivery. This means for example that a building engineer designs the house based on some standard model, which he changes according to discussions between sales person and customer. This often results in seemingly generic houses that do not capture most value of the plot. Log houses make no exception in the Finnish market, even if they are a somewhat luxury product abroad. Why do not people in Finland use architects for designing their log houses? Is it because of the price of the design work? How does the log manufacturer’s system of configuring houses work without architects? Are log house companies satisfied with the current system? Could mass customization strategies be suitable for developing design and production processes of log houses? This paper presents results of studying the need and supply of individuality of log houses, and current house design processes that let users participate configuring their new log homes in Finland. The study was carried out via consumer study and interviews of log house industry’s managing directors and sales personnel. All of these companies are building non-speculative individually-commissioned houses, building houses to meet customers’ individual orders rather than for stock. Based on our consumer study, there is a great demand for individual houses. Only 8,8% of the consumers would choose a standard house model. However only 10% of respondents would prefer a unique house designed by an architect, while 68.9% would prefer a modified standard model. Most important reason for not using architect is the price of the design work. This results in contradiction, since consumers want an individual house, but are not ready to pay for designing. Surprisingly, all interviewed managing directors of log house companies said they produce only individual houses. Customers always want some modifications even in the standard models, and that results in designing each house anew. This has a negative effect on the profits of the companies, since design work is included in the price of the house delivery. What customers might not realize is that when design work is done at the risk of house builders or even sales people, it is done with as little effort and cost as possible. Since the existing design process of log houses produces often seemingly generic but always laboriously planned houses, there would be need for improvement. Systematization of individual choices could benefit log house companies in terms of design resources. And If mass customization approach would bring architectural quality available to a broader group of new log house dwellers, they would benefit, too.
