I couldn't find blueprints/city plans(Sim Settlements) that fit my aesthetic so I decided to build my own settlements. My aesthetic is simple, clean and tidy,  nothing extravagant or impressive. Itry to keep each settlement distinct but the smaller settlements are pretty much cookie-cutter. I use clipboard Resurrection to copy and paste (furnished) prefab townhouses from Snappy Housekit. Most of them use the awesome Clean and Simple mods as a base.

Required mods: check above. I'd like to thank all the mod authors that made these settlement blueprints possible! 

Recommended mods:

• Private Area Markers
• Clipboard Resurrection
• Workshop Plus
• Workshop Framework
• Scrap Everything
• Immersive Vendors
• Clean Barns
• Clean Warehouses

Blueprint Slots
*These are settlements I'm particularly proud of!
The grass in most of the pictures are from a grass mod. Without one, grass shouldn't be poking out of the floorboards (usually).
I wanted to add more clutter but I wasn't able to find ones I liked so there are many empty shelves.
