If you guys get a chance check out my new home mod. Its a megaton replacement. I know there's already a ton of them but this one is a little different and I actually just made it for myself but thought it might be good enough to share. Let me know what you think.

I like it. Though it's a bit to dirt/rusty for me. You would think after 200 years someone would take care of that place and clean all that dirt and rust..

The only issue I see is Vaults are supposed to be underground. So, you could place a hatch under the existing house to access the Vault House, to keep in the lore as it were.
