Density is Home is the new book of the Density series of a+t architecture publishers. It echoes the 5 types of city -dispersed, expansive, modern, the core of the city and the recycled city- where we live today through 37 projects on collective housing. 14 case studies have been extracted among them in order to analyze the desirable home.

One of the first persons to propose high-rise social housing was Ernö Goldfinger, with a scheme for housing and circulation similar to that of L’Unité.

The Institute of Architectural Typologies at Graz University of Technology held the Dense Cities symposium last May. The speakers addressed the broad topic of urban density and its relevance to actual production of architecture.

After observing the decline for twenty years, the town planning regulations of central Manhattan went back to promoting mixed-use buildings. The Galleria was the first to be built under the new regulations.

Located in Bloomsbury, this complex was conceived as a three-level plaza running the length of the block and linking directly with the surrounding road.

The lineal city rather than the intense city is the aim of this ambitious project for social housing, inheritor of the Le Corbusier scheme.

The Monte Amiata complex was another attempt at a laboratory reproduction of urban complexity, again outside the city.

The original project was made up of two towers, one for housing and the other for offices, which became only one with residential use on the upper floors.

Park Hill was born of the proposal of a new way of city building different to the functionalist model of L’Unité d’habitation. It was the first time the ideas promoted by the members of the Team 10 materialised, although the authors of the project were young architects who were not members of the team themselves.

Javier Arpa, architect and editor of a+t, will be giving a talk called This is Hybrid. Análisis de los edificios de usos múltiples next Monday at the campus of the Universidad Pontificia de Salamanca in Madrid.

A city within the city was the slogan used by the author to promote his mixed use complex. Marina City was the first high-rise residential project built in post- war Chicago.

L’Unité of Marseilles was the first opportunity Le Corbusier had to build his machine à habiter, basic prototype of his green highrise city, with all the services vertically integrated.
