I think one of the best things about this mod is the pre-built village cottages. So I was trying to figure out how big each cottage is, and couldn't find it, so I decided to just go ahead and build each one, and find out.

Note that cottages 1-8 cannot be built on foundations, and cannot be used as houses or useful buildings - they are just for decoration. But 9-14 can be built on foundations, and you can put stairs in them, doors on them, and live in them like little homes. So here are the sizes and usefulness of each of the 14 cottages available in this mod. (Sizes given in foundations)

Cottage 1 - 2 1/2 X 3 1/2
Cottage 2 - 4 X 4
Cottage 3 - 3 X 3
Cottage 4 - 4 X 4
Cottage 5 - 4 X 5
Cottage 6 - 3 X 4
Cottage 7 - 4 X 6
Cottage 8 - 4 X 7 - biggest non-usable house - looks like a mansion!
Cottage 9 - 2 X 5 1/2 - uses 1 double tier stairs, and a ladder to get to the attic, and 1 door
Cottage 10 - 3 1/2 X 4 - uses 2 single tier stairs, and 2 doors - only 1 door snaps to the frame (you have to eye the second door, but it will work)
Cottage 11 - 3 1/2 X 4 - uses 2 double tier stairs - top one stacks on the bottom one; has a nice 2nd floor balcony; uses 3 doors (again, only 1 snaps to frame, but the other 2 will work)
Cottage 12 - 4 X 5 - uses 2 single tier stairs, and 2 doors
Cottage 13 - 2 X 4 1/2 - small single floor cottage with 1 door
Cottage 14 - 3 1/2 x 4 - there is a second floor, but I haven't figured out how to get the stairs to work - I even tried the vanilla wooden stairs, and even the wooden stairs from the S+ mod, but I couldn't get any of them to work right. The only one that kind of works is the Double tier stairs, but they stick out of the side of the house.

Anyway, enjoy. As I mentioned, I like to put cottages 9-14 on foundations, that way the floor doesn't have grass sticking up through it. If you place cottages 1-8 on a hill, be sure to be facing UP the hill, so it sits into the hill. Otherwise, the cottage will stick out above the ground with no support.
