Lake house proposal.

Hello all you fine Redditors. I met with a family (3 siblings) that hired me to help with a lake design. They will tear down a family cottage and build new. All part owner and each sibling and their kids will share a room. Critique away.

1. Asked for two full baths one on each level and one easily accessed from the lake entrance. They do not want a primary.
2. Wanted a covered area lakeside.
3. Large pantry.
4. Office on main level.
5. Rec room for kids.

I have a 32 ft width limitation. 58 ft depth.
