Malley Phare, an architectural symbol with a height of 60 meters, is an exemplary object from an energy and socio-cultural point of view. The use of wood from almost exclusively indigenous sources allows us to meet several challenges: application of the principles of the 2000 Watts society, increased energy performance, sustainable development, reduction of the duration of the construction site, lightness of the structure. The Malley Phare elevation is composed of 14 floors divided by 3 typical floors. This organization creates a façade design composed of slots, notches and loggias. Several common spaces are available to the inhabitants: "jokers" rooms as well as coworking and home office premises (double height) that encourage teleworking and meet a growing and current need.
