Hello and welcome to the forums! Congratulations on joining mods! The forum members here are definitely a wonderful bunch of people. Are you just needing help with getting your walkways to match?

Your first link points to Lewanda's house in purple, which uses the games original walkway (road). Your 2nd link points to bbaby's house with Airy Workroom, which has a different walkway (road). Your 3rd room points to the Airy Workroom with the games original walkway (road). Your 4th link mentioning the barn also points to bbaby's house with Airy Workroom. Looking for the barn (shed) led me here. Is this the barn/shed you were referring to? If not, if you look in the Shed Mod Directory here, you can identify which shed/barn you are using.

You also mention that the bushes along the top aren't joined properly. Are you referring to the bushes and plants at the top of the game (outside the backdoor by the kitchen)?

If you are able to post a screenshot to the forum of what you would like help fixing it would be very helpful. You can find instructions on how to take a screenshot and upload it using the forums File Manager here. With so many wonderful mods a picture helps everyone know what rooms you're using. Good luck and again WELCOME!
