opposite: Calligraphy blocks – tectonic detail. The articulation of the facades is a function of the location within the urban field. Theexterior of the blocks is given a heavier relief than the interior. Where a block opens up and the public space flows into the privatecourtyard, a semi-private zone is articulated via the gradient transformation between the outer and inner articulation.below: Close-up of cross towers. The cross towers produce the urban peaks. Through their ground-level articulation these tower complexesparticipate in the creation of a continuous urban fabric that frames the streets and occasionally widens the street space into semi-publicplazas. This is achieved while maintaining total continuity between the podium-like ground fabric and the shafts of the towers.
