Trott Cottage Aframe on Lake Menominee, Muskoka, Ontario.

Pretty a-frame cottage with a lake view.

Lake Menominee in Muskoka, Ontario.

There is something about A-frames that are so beautiful.

Usually on these exposed interior framing houses they use something called "outsulation", a rigid (usually foam board) on top of the weather barriered sheathing.  Kind of like how they insulate on top of a roof deck.
