Shandy graph paper is the ideal way when making tenplates. You can get a pad of these for little more than a pound. I have very carefully measured out my kitchen, on a graph sheet, and then cut out small pieces for such items as washing machine, oven, dishwasher, sink, etc. etc. I spend ages playing around with this.
Our block of flats ares side-on to a Main Road. Benefits are that there is a bus stop right outside, and opposite. Yes, we do get some traffice noise, but have quickly become quite used to that. At least, when I stand on my balcony I can see people around - which was great during lockdown periods over past 18 months. During the night traffic is very minimal, so even with my windows open all the time, has had no effect whatsoever on me. A further benefit is that this Main Road is lined its entire length with gorgeous cherry trees, as I am on the first floor, I look out, from my Living room, directly to their tree top greenery, and in the spring, the wonderful pink cherry blossom.
This is the first time I have ever lived on a main road, and I was a little concerned - but it has actually proved beneficial.
