Throughout the last 200 years, the strictures of the rigid Manhattan grid has become a unique laboratory for new urban prototypes. Cleverly analyzed by Koolhaas’ City of the Captive Glove, the repetition of this prototypical block in plan has engendered extreme diversity and ingenuity in section, resulting in projects that simultaneously respect and contest the rigidity of the grid. Today, as the city strains to house an ever-densifying population, old models of housing are becoming increasingly obsolete. The moment is thus ripe to once again explore the architectural and urbanistic potential of prototypical high-density block typologies - the tower & plinth commonly found in 21st century development models driven solely by maximum efficiency and financial pro forma. This design research thus challenges these derived typologies by exploring potential new relationships between density and open space, private and public, the grid and the block, and the mixing of land use & programming in order to shape new modalities of domestic space with the potential to inform the future evolution of the broader modern metropolis.
Operation: Grafting the Cruciform Tower to the Perimeter Block
Corbusier’s infamous cruciform tower has been adapted by many through its history. Through its transmutation, the criticism of such towers is in the way the cruciform meets the ground, splitting its site into 4 separate parcels, the shape oft associated with failed social housing developments. This exercise offers an opportunity to graft this famed tower onto a perimeter block by splitting its 4 legs. Doing so allows the efficiency of the cruciform shape to be maintained, while creating a new urban condition when it meets the ground, where a singular shared open space can be re-constructed. This new grafted typology allows collective social program to be introduced in its perimeter plinth, allowing retail & amenities to be lifted at higher FAR densities.
Operation: Angling the Tower-Plinth Junction
The operation of angling the junction between the Tower and its Plinth allows terraced typologies of housing to be introduced in an otherwise horizontal & static plinth form. In addition, re-examining the junction point between the tower & plinth as an open void space creates a new shared urban relationship between the two disparate typologies. At higher densities, repetition of this typology allows cores to be shared between towers, retail to be elevated, and collective social or educational programs to be introduced underneath the terraced housing to activate the street in the 21st century city.
Operation: Lifting the Plinth
The stepped tower form combines the efficiency of vertical living with the private open space advantages of terraced forms of housing. The introduction of the stepped tower typology also allows for an opportunity to lift the plinth at higher densities to free the ground plane to communally shared open urban space. While ground bound, a typically retail plinth can be raised to allow collective social program to be introduced underneath, where at its highest densities, the plinth can become iconic & monumental cultural program for the broader city.
