Abstract
The aim of the study was to define and assign to an appropriate group the attributes that the client is looking for and requires when deciding to buy a summer house. This aim was achieved through the use of the KANO model, which helps to define and divide the attributes of a given product into four groups: must-have attributes, one-dimensional attributes, delighters and mistakes. The KANO model was used in a construction company in the process of designing a modern summer house. A questionnaire was carried out, the aim of which was to select a representative group and to investigate what attributes customers who decide to build a summer house are looking for. The result of the survey was the identification of 4 groups of attributes and obtaining information that could support the design of a modern summer house. The results showed that customers are looking for a summer house project, which has, among others attributes, solutions that can enable the house to be used as a year-round house.
