Maybe it's short solution, but not readable

Agreed - it is not clear why zip() is needed and there is no inline comment about it.

grounds is an array of x and y coordinates of all of the #'s. something like: ( ( 0, 1 ), ( 2, 3 ), ( 3, 4 ) ) zip(*grounds) separates out the x coordinates and the y coordinates into 2 separate arrays. continuing with the other example, It would be (( 0, 2, 4 ), ( 1, 3, 5 ))

In my opinion, this is a very clean solution because it basically says that the boundary of the house is from the smallest x coordinate to the largest x coordinate, and from the smallest y coordinate to the largest y coordinate.
