Contour modification on sloping site.

The video tries to clarify concept of contour modification for siting (locating) building on a sloping site. It gives introduction about contours, terminologies which you should explore further.
The concept gets clear if you try this out on a few examples.
PAUSE AFTER EVERY CASE DISCUSSED AND TAKE A RECAP OF THE PROCESS.
Locating a building on sloping site depends, not only on topography, but also on how the architect used the contour conditions to derive spaces in the building. Building location and orientation also has to keep in mind the site drainage. All such issues have not been touched in the video.
