First stop and think long term - 3 to 4 generations out. What do you want the place to be.
Consider :
ages of people who will use
docks , picnic table , boating access , outdoor parties ,swimming , swing sets , etc
trees - size now and later , bushes , walkways and paths to lake and around the lake for people and wildlife
view from the house to lake (see B'ski windows)
house orientation to water and woods (drive in and out).
Look for other people's set-ups here on the forum. B'ski threads (more than just the house thread IIRC) will help a lot with the thought process.
