In accordance with the mechanical-technical requirements it is possible to perform rationalization of the structure by changing the geometry of the cross-sectional element of wooden cladding by chamfering the edge which would improve the draining of water and thus the durability of the product. The choice of assembling facade cladding with the half groove joint and clips in relation to the classic tongue and groove joint also contributes to the extension of the durability of wooden facade. The rationalization was also carried out on assembling of the characteristic corner details. The justification for selecting ash for making wooden facade elements is reflected in the availability of raw materials in Croatia, while dimensional stability is improved through the heat treatment process ,which is one of the most important factors. By examining the trends in architecture in Europe it can be expected that the application of the wooden cladding will increase. Due to the growing trend of manufacturing of mobile houses it was observed that the variety of offer on the market is very small. The difference in products between individual producers is reflected mainly in interior design with lower price range in which the diversity of exterior walls are different colors of facades. Complete or partial installation of wooden cladding on mobile house can offer an expanded range of products with a higher price range to the market. The total installation price of wooden cladding on the example of the mobile house of 32 m² increases the price of mobile house by 25,44%.
