First map sketch of my House. It's basic but it's my first try ;)
Some notes about this first try:
1- You should create a grid from the begining, doesn't matter the type of grid you use. It makes easier to put the elements on a map.
2- It Is necessary to identify the most important references on your map. It took me a while to understand which were my reference points.
Things I would like to play with on my second map:
3- Better iconography
4- Better legends
