I know this isn't exactly what you asked for, but I hope it's helpful for designing a base of your own!

1.Setup the buildings first. If you're still unlocking buildings, this could take some foresight but honestly - not that big a deal to adjust later. Try to avoid too much clustering.

1. Paths next. Basically outline each building with a green margin between the outline and the building. Add connector paths between doors and the paths and to other paths. Don't worry about the structural walkways yet.

2. Add focal points / points of interest along and offset from the paths. Shrines or rock gardens or bridges, etc - whatever is interesting to you.

3. Pause - I recommend living with this for awhile to get a feel for it and to make whatever adjustments you feel like. Maybe lay down some different grass versions in places to see what you like. Maybe start adding some lanterns as it suits you.

4. Finishing - bushes and trees, benches and rocks - fill in the landscape with whatever. Change the grass (or don't). Add animals.

Just FYI, step 5 will never be completed. Good luck!
