I have all types. A large big energy investment home should have:
- a place for comfort buff at max.

- storage. Personally I put storage near what its for, eg metal bar box near forge, raw and cooked foods have chests in the kitchen, even my ferment barrel has a chest of completed meads and raw.

- crafting. all stations fully upgraded. more on this later.

- kitchen: this means cooking station, oven, cooking pot, and ugprades with smoke handled. More on this as well.

- big crafting (smelter, kiln, etc can be inside if you handle smoke, or outside, etc)
- farming area
- ocean access and boating launch (simple or complicated)
- defenses: moat/wall/etc
- portals. at least 2, one that is always locked and unconnected for use when exploring, and one that you can dial to others (I keep signs as to what name leads where). I recommend closer to 5, as there are some others you may like to lock (vendor, spawn point, alternate homes / farms) all the time.

-----------------
ok, so ... there are any number of ways to do all that.
my go-to design for a large home is kitchen on top, so the smoke is handled naturally (usually, the smoke simply goes outside without a chimney at all, like put the hearth against your outside wall and put a wall above it at viking head height. then use a roof tile to shift the smoke out one tile and cover it from rain)
and my comfort 'bedroom' below that, with the hot-tub also stuck into the outside wall with the smoke out of my way.
and the bottom levels become crafting and storage. If you want to have indoor smoke crafting, it can go upstairs with the kitchen or vented some other way.

--------------------------
and, a home does not have to be that big for all this crap. My current home, which I simply LOVE to be in and use, is a single 6x6 floor tile square, with 2 of the outer walls lined with crafting stations (no smokey ones) and a pit dug under the floor with all the comfort and crafting upgrades that get in my way. Its a trainwreck down there, but everything is out of sight, leaving me a sparse bedroom with max comfort doubling as a kitchen, a small attic storage space, and a simple crafting area that is fully functional yet tightly packed. As for smokey crafting, I have a chest of all the mats to make any of the bits hidden in an exterior wall with lawn access, and I just build and destroy as needed: I don't do very much of this anymore, just ammo mats really, or occasional iron runs.

for my dock, I level an area where I can no longer use my pick in calm waters, just that high, about boat size square. I break the boat there and can get my stuff back in the shallows. I raised earth to just above the waves in a storm (missed this by a meter or two so it gets wet now and then) and put down rock stairs and floors and a small storage shed to complete the dock idea.

a full home with everything visible and placed artistically needs about 10x10 X3 space assuming a fair portal hub and storage area. A tight home with it all buried I did in 6x6 as I said.
massive storage areas are tricky. I have put chests down into the floor, carefully making it parallel so its smooth to walk on, then you can do the same to make a wall of chests that are more or less flat. I recommend labels. But again, I don't do a lot of that, I prefer store where it is used approach with a junk box to dump in mid-runs (sort it later idea) and overflow storage for things I have too much of.


here is my partly complete (finished it and redid decor later) ... stairs up to storage chests, kitchen on the outer wall (with hot tub at the kitchen wall under the floor), chests make up part of the floor (added another by the oven) and small one at foot of bed) and the 2 doors lead to the wrap around crafting hallway that is just wide enough to walk through and use stations.

another home, a full rather large one, the kitchen on top (the hearth is directly over my bed) in the open air (poles loft a roof) and a gap in the stone walls that you can't quite see leads to smelter/kiln/windmill/etc out in the open air (no roof at all on that part). Smoke all handled by being on top, basically a large circle design, goes down to bedroom, then crafting room, then storage room.

location is everything, this is both meadows and plains, for farming reasons, and because its an awesome island, scenic.
