On a plot of land of only 6m x 15m (90 m2), with a single front facing north, there is a plot of land with very peculiar characteristics, since it has practically zero sidewalk level. It had a constant drop of 2.50 meters, so the usual solution in the area was to generate fills to level it. Contrary to that, the decision was made to take advantage of the natural topography and instead of investing resources in fills that would remain buried, it was decided to make useful space for each of the m3 of the project, converting what for many was a disadvantage, into a great benefit.
