Need a house on a lake with a dock

[Zespa]

I'm working on a movie that's set mostly in a two-story house on a lake. We've pretty much built the interiors of both floors, but are not sure how to go about building the exterior. There's a dirt driveway leading up to the house on one side and a ramp going down to the downstairs storage area and a ramp going up to a deck that leads into the upstairs living area. On the other side of the house, off the downstairs area, is a dock that goes over the lake, with a simple row boat tied to the end of it. There are scenes in all these areas, including on the lake itself in the row boat. 

Please let me know if you have anything or want to build something that would work.

Thanks!!
