The question was how to combine two heterogenic, chaotic, mixed used neighborhoods on both sides of the Lammenschansweg and how to change it into an attractive, coherent, urban district? We analyzed the existing urban fabric of a typical, historically grown block of Leiden to create a new type of building block: the intensive Cityplot. Our main answer came from a clear backbone of horizontal lanes combines both neighborhoods, vertical and diagonal streets adopted from the existing structure complete the new urban fabric. Bij giving the existing buildings creative, temporary functions, the urban fabric can develop gradually without having unpleasant living areas.

We asked ourself, how to gradually transform and densify existing areas in the city instead expanding te city in one time? Can we achieve this bij composing the requested program for phase1, with collective small-scale initiatives without losing a strong, coherent identity? The new district should be a part of the existing city of Leiden, so the urban fabric must be flexible and suitable for mixed use and a high density. We developed a variety of different housing-, working-, commercial- and parking typologies, which can form together one intensive Cityplot. Within one plot various design are possible which makes the urban fabric extremely flexible.
