The ingenuity of Can Lis lies in its reinterpretation of traditional Majorcan building methods and the use of local building materials.

Can Lis was planned an organic, unified whole, its layout framing the day-to-day events that marked Utzon family life. Jørn Utzon's ideology centred on this very phenomenon - that architecture is not an external form: it is primarily the frame that encloses a collection of ritualized events. Precise studies in 1:1 of the site potential resulted in a set of interim drawings. Based on these drawings and with the help of the local building contractor Jaime Vidal, the house's final design emerged during the course of the building process.

Can Lis has been singled out by several leading architecture critics as one of the most important houses of the 20th century.
