When i initiated a transfer, it ended up being replaced, but sometimes that doesnt always happen. I'd also recommend scraping the original player home completely as i've completely replaced it. I'd first recommend using Sanctuary Reworked Roads, and Sanctuary Hills Repair and Cleanup, as it cleans up alot of the random debris in most of the house buildings.
I personally use Fusebox Generators and Power Conduits and Pylons for my electrical wiring needs, and only for what truly needs wiring, but feel free to setup with what works for you.
Also added updated bathroom with full working fixtures and even a LooksMenu Mirror for whenever you want a haircut or needless cosmetic surgery.
I've even afforded space for the Minutemen to expand their artillery coverage. And I've also greatly expanded the ability of its defenses and guard population. I've resurrected a long dead food franchise, and even expanded its purview. I've retained and re-purposed the existing buildings into storefronts, patched up the holes that Sturges griped about so much, created proper barriers to protect the Home Settlement, provided a proper workshop for the Sole Survivor, while restoring their former home to its former glory. Here's my version of Sanctuary Hills: light on numerous huge buildings, but still packed with everything a post-war settlement needs. Instead of building a bunch of wood or metal sheds that look rundown, or using a bunch of mod-added building materials that don't mesh with the overall design of the settlement, i've used the exisiting houses as shops, and added buildings that match the domestic designs as the rest.
