Problems of convex space drawing in space syntax : Case of 4 model houses with concave space |
| Abstract |
In Space Syntax, developed by Bill Hiller(et al.), a plan is redrawn as a convex plan for analysis of the space complex. It means every unit spaces should be divided as convex if it were a concave one. The continuous visibility within the space(be it a road or a room) was the key reason of this convex conversion. But, the concept of convex is not consistant in the analysis of building plans; Some applys it(T.Markus, 1993), and some is not obvious(B. Hillier, 1984), some does not(M. Shoul, 1993), A varient way of convex plan drawing may induce varient syntactic analysis, thus leading to different space analysis. This raises conflicts and asks us to know about the influence of convex plan drawing and to develope some technics. The paper tries to find an appropriate method of convex drawing through a simple simulation of 4 kinds of convex drawing methods; concave pattern(1 unit), short line division(2 units), double division(3 units), long line devision(2 units). This concept was applied to 4 model houses; each of them have a L-shaped(and T-shaped) concave space unit which acts as focus, ie. mare(daecheong) or living room. the process was next following; general space characteristics of 4 models were defined; a syntactic analysis(RRA.RC) of them with different methods(thus total 16 convex plans) was conducted; the results were reflected to the general space characteristics. It reveals range of similarity and difference in the function of 4 convex drawing methods, and finally proposes short line division as an appropriate method. |
