Description of the project: 


Located in the municipalities of Lausanne and Mont-sur-Lausanne, the Maillefer district (77’000m2) was built in three phases from 2008 to 2019. The objective of developing such a modernly designed district was to offer its inhabitants pleasant accommodation in harmony with the surrounding countryside.
In this district, the Société Coopérative d’Habitation Lausanne (SCHL) built the first eco-neighbourhood in French-speaking Switzerland with 300 apartments. In the second phase, Retraites Populaires built three buildings, including a 17-storey tower, with 128 housing units and 3000 m2 of commercial space. The third phase, carried out by Retraites Populaires and SCHL, resulted in the construction of 155 housing units. The site now has 585 apartments, making a concrete contribution to tackling the housing shortage.
This complex is the result of close collaboration with the sole owner of the plots, the Livio Family, who has made the land available for 80 years as distinct, permanent leases. The district, which is seen as having a social function, is part of the soft mobility plan of the two municipalities, making it possible to ensure continuity with existing cycle lanes and pedestrian paths.
For the first stage, which included 15 buildings, it was important to promote architecture that encouraged encounters between tenants. To this end, playgrounds and recreational areas were provided in the access alleys to the buildings.
As part of the second and third stages, Retraites Populaires built four buildings and spaces dedicated to shops and services for the inhabitants as well as for visiting customers. A 17-storey tower was also built, as a first in the Department without any opposition. The resulting freed ground made it possible to create a large wooded park and a playground. Conceived as a natural mineral from the ground, its facades are made of prefabricated concrete. Buildings A and D, developed lengthwise parallel to the Chemin de Maillefer, are situated between the boundaries of the plot and, on each side, a landscaped, green park.
The functional mix, the neighbourhood life, the different types of affordable apartments ranging from one to six rooms, the shared premises used by inhabitants, the wealth of outdoor facilities with its parks and playgrounds, make this district a successful example of good collaboration between land owners, developers, architects and residents. Thanks to the architectural coherence of the complex, this district has its own life but remains very well connected to the urban context of the two Municipalities in which it is located.
