Symbiosis of functions in an urban parasite.

New Urban Worms, a new nomadic residential form which is, literally, planted on existing facades, is a largescale urban interpretation of the Rucksack House of the German sculptor Stefan Eberstadt. Every city is engaged in a search for innovative solutions to the shortage of building land which raises issues of urban identity and aesthetics. Thus - while located in Madrid- This project is aimed at all metropolises.

The aim is to increase densities by hanging clusters of small cubic units to such places as the cornices of existing buildings. This small living or working spaces can be multiply into a sinusoidal, architectural worm, running across the facade.

The morphological form is invertebrate - a flexible body, which can be strecthed horizontally and vertically - and is both dependent upon and yet completely autonomous from the existing building, in that the occupant is free to choose where and whether to hang the structure to create the extra space. And it can be applied to a wide range of buildings - offices, bridge, basilica...

The units are clad with differing materials and width. The alternating photovoltaic and polycarbonate panels which form the worm's walls create and aesthetic which is both powerful and playful while also guaranteeing an adequate energy supply.

The random way in which this units can be fixed at strategic points in the city create elements of surprise: Real parasite which also serve to criticise the shortcomings of the European city...
