But turtles do not use coordinates, if anything they use (relative) polar coordinates ... Oh, maybe you first coordinatize the house drawing and then make turtle commands from that? It seems that turtle programs don't need any mathematical priming....

    from turtle import *
    goto(20, 0)
    goto(40, -30)
    # etc

turtle.py first introduced by G van Rossum in 1998.

Polar coordinates are coordinates too, and besides they can use cartesian coordinates as well as long as you use 'up', 'down', 'right' and 'left' commands, after all the fact that they are relative doesn't really matter all that much.
