Here is a little tidbit from my progress on my playthrough of Agrarian skies:
The first house is taking shape. it's in it's third iteration now, and the bottom half has gotten it's final shape. a Lot of detailing is still missing ofc, but I did get some of the hanging bushes placed on the ground level back porch. (a back porch with nothing but an endless drop below it. damn that was hairy to build)
This house is going to be the stonemasons house, and the first floor is going to be a workshop/storage area for cobble,smoothstone and other stone products as needed. I'l perhaps make a house next to it with the functionality for making the mossy and cracked varieties next door as well. If I have room, I will also put a clayworkers house on it, thus this Island will cover most of my building materials needs. there is room inside for a mob grinder to dirt setup as well, but i can also do that with carrots or some other food item.
I'm definitely open to ideas on that, since I have a hard time visualizing anything nice that far ahead.
