Did a rough study on the possibility of overall arrangement. the difference between 4 storey, 5 storey and 6 storey on a 1 hectare (10 000m2) piece of land. It seems like 5 storey seems to be a better choice to meet the density requirement and at the same time provide interesting spatial quality. Particularly the option with 9 main courtyard of 22m by 22m. The depth of the blocks are varied to see the implication of the depth on the overall layout.The next step would be to do sectional studies and 3d studies on the various options and to pick a site. Currently, I am studying punggol to see if there is any suitable site . Feel free to comment.
