LAN architecture designed this double skinned residential building for a competition in paris. although they
eventually lost out in the competition the building has a number of unique features worth highlighting.
the structure of the building is rather distinct because it uses a double skin that helps insulate the building,
while the outer most skin produces energy through photovoltaic cells. composed of meta, this outer layer
would also serve as a sun barrier all year long, giving the building high thermal performance. the design of
the building aimed to integrate compact living in a vertical tower. the building would have bordered a park
on the south and west, overlooking the city of paris.
