Unfortunately, I cannot identify your Google map. Is the thing oriented to north or is the small compass in the top right relevant? To which street do you now have to align the eaves? Is there a street running through the property to the left of you or is it still going to be built?
Your floor plan attempt reminds me a bit of the "Jedermann Klassik" by Büdenbender. Without an upper floor, a floor plan is worth nothing as long as you are not planning a bungalow.
