3D Motion Grid City Studies

3-Dimensional Venn Diagram study of architectural and urban design functional use relationships in three dimensional space. From a 1966 diary of Dennis Holloay, after discussions with U.Mich Prof. Walter Sauders, and additional inspiration from Christorpher Alexander's "Notes on a Synthsis of Form", Frank Lloyd Wright's Unity Temple, William Seitz' "The Responsive Eye", and Paul Klee's "Diaries".

Study of urban three-dimensional spacial uses arranged around, and arganized by, movement path infrastructure with "labyrinthine clarity". From a 1966 diary of Dennis Holloway, with inspiration from Aldo van Eyck, and CIAM Team 10.

3D Motion Grid City project team collaboration with W.Brown, P.Forbes, D.Holloway, and Sociologist, J.Vanek, The isometric of the team's germinal idea for a "City in Space", vis-a-vis, a "City of Towers. (isometric drawing by Dennis Holloway, Ink pen on vellum, 1966).

3D Motion Grid City, first collaborative team model, University of Michigan. The Project was inspired by crystalography.

3D Motion Grid City Again was the second semester collaboration of the U.Michigan team, which morphed the circulation matrix from orthagonal (first semester) to tetrahedral. The functions of the City were stratified by the need for, and relationship to, daylight and solar energy, with housing on th exterior surface of the City, and other uses arranged as required on lower levels. The 3D City reorganized the urban idea, by leaving the natural landscape free for recreation and agriculture, while increasing dense clustering of all urban functions into megastructural island-mountains, connected by a high-speed transit grid.
