Here is a pic of the dock as was is being built, several weeks ago. It's nearly completed now. The upper deck is 29' by 35'. Over 1,000 sf.
Downstairs is a 10' by 30' deck that is carved into the hill. In the picture, the workers are putting in that deck. There is a 6' high retaining wall all around it. I'm going to add a big outdoor kitchen on that deck like you've seen on tv. There will be a massive 46 by 47' hip roof over the entire thing including the outdoor kitchen.
The houseboat would be moored on the right of the ramp that leads down to the lower deck.
Here's the sunset I would see every night from the upper deck.
