The first part of this sequence is shown in the first 4 screenshots on the previous page.
When you choose to go down and to the right in the building after the first hanging banner, you'll then need to jump onto a narrow, white plank.
As you walk across it toward the next building, it tilts downward. Jump from the end of the plank into the next building.
Here you can either run forward and jump to grab the edge of the next house or move onto the outside ledge on the right and jump from there to the dangling crate.
If you go through the building instead of jumping onto the crate, return to the previous page and pick up the walkthrough at the 7th screenshot, which is marked with an *.
From the dangling crate, jump to grab the edge of the narrow, white plank above.
Pull up and walk along the plank onto a section of brown plank.
Then jump the gap onto the next white plank ahead.
As you move forward, the plank tilts downward. Jump from the end of it to grab the edge of the building with the dilapidated shoji wall ahead.
Pull up and move through the building.
As this house tilts forward, jump down into the next one, which has a ramp on its near edge. Veer right to cross the floor of this house. Then jump down into the next one. At this point, the floor tilts forward and Lara slides into a larger, more solid building, and a cut scene begins.
