Just got done recently building our new home and GC’ing the project myself. We went with a floating slab single level with a 8/12 vaulted ceiling in the kitchen/living area. We always wanted a wall of windows with a view of the lake.
Take time planning and think about everything 3 times lol. Crazy how many times we changed our minds on something and how many things we would already of wanted to do differently.
One big factor to the design would be if you are planning on using year round. If your doing a floating slab, you’ll be installing infloor and running it all winter to keep frost away. I am in the plumbing/HVAC industry and you can PM me system questions. We went with an infloor system with central air, also an Aprilaire and ERV. Total comfort and humidity control. Also did a side arm tank from the boiler to heat our hot water. Much more efficient than a water heater.
Other things I would definitely surrounding our hobbies that we incorporated. Tall sidewalls in the garage, tallest garage doors you need (if you plan on another wheelhouse), 18’ wide double door, insulated and heated with infloor, garage walls and ceiling lined with pole barn tin, floor drain, ceiling fans in the garage, 30 amp RV outlet, hot water spigot with hose reel, and a utility sink in the garage.
