Just wondering, how a sloping site affects the feasibility and cost of a basement carpark.
Specifically, if a site has a slight slope downhill from the front of the block to the back, how can you "calculate" what the ground level is. From my understanding, a basement carpark can protrude above ground by up to 1 metre from ground level. Would you just take the median level of the block ? In this case, quite a large chunk of the basement carpark would be mostly above ground, toward the rear of the block.
Also, would such a site mean it's cheaper because there is less excavation required ?
