In 2016, Greenpeace Spain plans to move its offices, until then located in a rented first floor in a block on Calle San Bernardo, in Madrid. Greenpeace asked us to carry out a feasibility study to decide between the different options they were considering. After a detailed analysis of the different possibilities, we opted for a disused industrial warehouse, located in Calle Salamanca, for which we carried out different simulations of occupation, organization and operation.
