The project of the city in space was eventually able to take shape on a
suburban plot formerly occupied by a cement factory. Working to a budget
appreciably lower than the norm for subsidized housing at the time,
with unusual funding, Walden-7 rose up as a monument and point of
reference in this area to the west of Barcelona. The building is
composed of 18 towers which are displaced from their base, forming a
curve and coming into contact with the neighbouring towers. The result
is a vertical labyrinth with seven interconnecting interior courtyards,
as far removed as possible from the model of the uniform, repetitive
housing block. The considerable area originally devoted to communal uses
was reduced to allow an increased number of apartments. These apartments are formed on the basis of one or
more 30 m2 (35.8 sq. yards) square modules creating, on different
levels, dwellings that range from a studio consisting of a single module
to a large, four-module apartment.Program complex of 446 dwellings, public spaces, meeting rooms, games
rooms, bars and shops on the ground floor, and two swimming pools on the
flat roof.
