The project consists of renovating and enlarging a traditional rural house from Brittany so that it becomes a comfortable house and a visible expression of the desire to enhance the heritage.
 
Estimated to have been built in the 19th century, the plot of land and construction on the same site already appear on Napoleonian plans of 1837. The house has characteristic features specific to its environment, bearing a strong historical heritage mark. To this type of construction belongs the house with only one “end” and single hearth, called Penn-ti in lower Cornouaille.
 
Originally, this term has a legal meaning and literally designates the “end of the house” conceded, consisting of a ground floor and an attic, with floor, fireplace, door, and window. An extension is planned, visible from the north where the land extends. On the other hand, the public circulation space is so limited around the southern perimeter, the extension cannot be seen and the house maintains its traditional and discreet character.
 
To meet the context of the site, the extension plan is rectangular and of similar proportion, with a cutaway. This +3 form of the plan creates a twist in the facade bringing a strong and intriguing geometric dynamic to the new addition. This faceted geometry, inspired by blocks from granitic yards, refers softly to the pre-existing architecture and generates an interpretation suitable for the 21st century.
