Floor plan of a single-family house, slight slope location, northwest orientation

The love handles don't care whether the neighbors saw the cream on the cake. My assessment here, rather pro basement, has been confirmed. Does the terrain only rise in depth, i.e., straight sideways? What matters to me primarily on the terrace is dry feet. Whoever shapes the terrain puts on the shoe of drainage responsibility.

The lateral terrain slope is straight to very slightly descending towards the right side of the plan. Significantly less than upwards on the plan. Was not calculated separately

So negligible, sideways no more than 0.2 m fluctuating?
