Rebstockpark - The development of a concept
[Rebstockpark - History with a future ->]
THE WINNING CONCEPT.
An innovative, cohesive design concept with ample room for architectural interpretation. New York star architect Peter Eisenman´s vision was selected by an international competition to become the development plan for Rebstockpark.
In a conscious departure from classical city planning principles, this plan details a clear, innovative organizational cohesion. The result is a sequentially flowing space rather than random placement. The architectural-political meaning of this avant-garde organizational principle lies in the city-planning dimension. Architectural structures and free space are subject to this principle, and thereby recognizably with another united. However, there is still ample room for architectural freedom.
Model of the design concept of Rebstockpark
PETER EISENMAN
and his vision of innovative city-planning. Eisenman developed a three dimensional functional model which serves as a basis for all elements - topography, buildings, streets, flora, lighting, etc - in all dimensions.
His goal was the development of a contemporary architectural language, oriented toward the complexity of modern reality and its interpretation as influenced by the media. The central conceptual element for the Rebstockpark plan is the fold - derived from the mathematical model of the fold concept contained in the chaos theory of René Thoms and Gilles Deleuzes´ concept of folding. The familiar orthogonal organizational system is replaced with an expanded one that is not restricted to right angles. The terrain is modeled by two grids each of which is a twist of one of the Cartesian planes that are used to model property borders. The relationship of individual buildings to another as well as that of the buildings to free space is determined by the fold.

THE IDEA OF FOLDING AND UNFOLDING.
The multidimensional grid as basic design principle. The arrangement of the Rebstockpark property is the result of a complete reorganization, which is most evident in the planning of the nature park and the structuring of a part of the construction site.
To satisfy each of these requirements, two grids were modeled, both of which are dependent on another. The "small grid" is spread over the construction site. The "large grid" is determined from the geometry of the "small grid" and the area occupied by the entire terrain. The concept consists of two basic aspects: requirements resulting from building height and usage, as well as those resulting from topography and the borders of the parcel as determined by its bordering streets. The following six steps are a somewhat simplified description of the derivation of the "small grid":1. First, the border of the construction site is framed with a rectangle that is formed by expanding a rectangle which encompasses the area of existing construction until it completely contains it.
2. The outer and inner rectangles are each overlaid with a grid formed with 7 horizontal and 7 vertical lines (7 is derived from Thom´s chaos theory), forming a 6 x 6 raster.
3. The raster points from the inner and outer grids are then connected. This is a two dimensional depiction of a three dimensional network.
4. This network acquires its spatial dimension in that it is assigned height coordinates which are derived from the maximal building height restrictions.

5. The result is a continuous, folded, spatial network. The rectangular building forms are then projected onto this network, and thereby acquire a trapezoidal form.

6. These trapezoidal forms are then projected back on to the original sketch. This defines the building borders which are to be incorporated into the building plan. The network lines also determine the route for streets and paths.
The result: a continuous three-dimensional grid
The derivation of the "large grid" from the "small grid":
- The "large grid" is derived by doubling the amplitude of the "small grid". Since the proportions of the entire terrain and that of the construction site are not identical, the large grid is expanded to 7 x 7 segments.
- This grid is then projected onto the picture of the entire site and distorted as required by the shape of the property.
- Finally, both grids are then merged in that grid points and project points are connected to another. The connection lines between these items form a new unit - the "large grid".
