Looking to build me my own personal home here in the next year. It will located on a hill overlooking a lake. I would like to have a home with an observation tower as the focal point in the house.

I love the PNW design style of this home:

My questions are:
Do you have any photos or know of any plans online I could look at to get a feel for the space?
