Presentation
			After graduating from the Tokyo Institute of Technology in Kazuo Shinohara's workshop in 1984, Yamashita founded the Hideyuki Yamashita in 1991, in Tokyo. Since 1989, Yamashita has been working on "containerising" architectural space. In 1993, he developed the Nested Cube in Process concept, which places a structure within another structure according to a geometric progression. Thanks to a play of mirrors integrated within this house project, the Nested Cube reflects and projects spaces like a prism. In 1997, he undertook a project for the Goree Memorial Competition in Dakar, Senegal, where the Memorial Museum spirals into space like a tree trunk splitting into two branches through a complex topological analysis, thereby negating oppositions of the static/dynamic or organic/geometric forms type. Yamashita collaborated with the Richard Rogers agency in London on certain projects in 1997-1998.

	NestedCube in Process, Kunimi-Machi, Oita, Japan, 1993		"NestedCube" to Decode - Live Feed Back Loop
			Two detached places in the "dialogue" are characterized as the same events taking place over and over again, only each time on a higher and higher level; it is an analogue to "recursively enumerable set". In the "NestedCube", a transgressive methodology; "recursively enumerable set" has been a central notion. A fully abstract, conceptual system of the representation of space, a system which would assert its potential perspective, leads us to such an apprehension: it would not try to let us step there physically, but perceive a phenomenal platform. It is a set of nested generations on a moniter screen.

	Time and space computer		Recursively Enumerable Space
			A loop connection of two pairs of cameras and monitors gives the image of two different frames repeating one after the other, visualizing "Place A" linked to "Place B" linked to "Place A" linked to "Place B"...etc. This system is for incorporated fully into the real space as a nested system. The notion of "recursively enumerable space" relies heavily upon the recognition of traditional Japanese architecture, beam/column structure and sliding partition system. Each element grows, being compounded out of previous elements by the repeated application of rules. Here is a simple but fundamental typographical manipulation.

	MicroShelter /D2 1993 - First price (inter-Intra Design selection '93)		Time Goes, Space Shifts
			The issues of "Time and Space" is related to the phenomena in a four-dimensional cube (hyper-cube), where architecture is newly re-organized in the interaction of detached spaces. The cubic structural frame of "Related Space" is representated as an equivalent of the continuous and infinite extension of space, though the receding repetition of the foreshortened picture frame. "Related Space" is in the preceding "dialogue" of the two detached places. "NestedCube" is a message to decode. "Info-Domino" is a conceptually developed scheme by means of the computer technology.

	Aoki House - 1996		Womb Within Womb
			"Torus" is a form to run different building systems, not by paralleling them, but by nesting them. Its base is the topology to renormalize a void within another void. It could be described as an inductive system where a womb generates another womb inside. This analogy demonstrates ambiguity in architecture, such that an exterior space unexpectedly turns to an interior space, or such that a door to the outside unexpectedly turns to the inside. This is not realistic, but gives a hint to re-organize architectural methodology.

	Concours pour une médiathèque 1995		Set and Reflection
			Space is renormalized (enveloped by and enveloping another mode of space). The "NestedCube" represents "renormalized space". It reflects and projects the attached spaces like a prism. It assembles and reflects the real spaces, so that the disposition of these spaces is renormalization. "NestedCube in Process" (weekend house project in Kyushu Japan) holds a "NestedCube" as the central concept in which two cubes are framed to form the simplest unit of torus. The "NestedCube" becomes a recursive space and a core of the structural system to support a nexus in combination with "attached spaces".

	National Library Competition, 1999		Relation to the Hyper-Cube
			The wire-frame axonometric drawing featuring the main structural members of the "NestedCube in Process" was quite similar to the drawing unfolding a four-dimensional cube (hyper-cube). Although the illusion of the four dimensions has no physical reality in the actual space, there is a strange coincidence in a geometrical sense. Of course nothing illusional would really occure in the actual physical experience in the space, but this analogy has been a radical index in architecture
