My favourites are the bell (so cute), flower arch, stone tablet, stonehenge and windmill. I would love the picnic blanket which I don't have yet...come on Diva!
I love how the illuminated heart looks in my town. I haven't had an uchi villager in my town for quite a while but I love all their PWP suggestions. Soon!
The lighthouse seems pretty neat. I would've loved to have it in my town, if it fit in the place I was originally planning on putting it.
Taking a quick look through the list, the wisteria trellis seems nice as well. I don't have it unlocked, though.
I like how the wisteria trellis looks, too bad my only uchi villager moved out before she could request it!
I also rather like how the tower looks, I'm trying to build it now but wooow it's expensive xD I'm only 200k out of the 700k needed.
