Here's my best effort so far at an overall plan of my apartment. It is not perfectly to scale- in fact, I may have the proportions of the kitchen wrong. I kept failing when I was starting with one room, trying to slot the others into place.
Starting with the hall made it easier, as each room-more or less- is on one side of the hall or the other. Now I'm going to start on a detailed plan of each separate room, with all it's wall outcroppings, windows, closets, doors and built-ins at the right places, and the right sizes. Then, I think I can use this general plan here to assemble the individual rooms into an accurate layout for the whole place.
It is quite confusing, as there are lots of odd corners, and it wraps around bits of another apartment, as well as a staircase- not mine- which I haven't actually been able to find from the outer hall.. Note that the sunroom/porch thing has a low window looking, darkly, on that staircase. And then there's the big hunk of enclosed solid wall between the dining room and pantry...I wonder what's with that...maybe pipes? The apartment's entrance hall has a little glitch from which the kitchen and "maid's room" doors are entered. And the kitchen door is set at a slant! These oddities and my own sort of directional/volumetric dyslexia have made this quite a challenge for me!
