I'll be pretty much ignoring chunk borders unless I'm dealing with things particularly sensitive to them, like ME drives and certain multiblocks. For chunk loading, I hope to be able to use a 5x5 chunkloader, but that's only if I can hunt down my other chunkloaders, since I'm entirely out of chunks. Spot loaders seem to ignore the limit, but they certainly cause issues from my experience. Whatever happens, I'll certainly be loading it. I don't even have any production equipment on site yet and the lack of chunk loading is already bothering me.
As for what this actually is, the two rooms are primarily decorative areas of Jormundgandr, which itself is a project meant to act as a new and secondary base. The main idea behind it was that my current base is asymmetrical, illogical, and the like, so Jormundgandr will be one consistently themed building. (#BlameAqua) The base will also be housing more lag-efficient methods of mass production than the old one, and the old systems will be removed as necessary, so I profit resources and everyone profits TPS. The base is currently open to limited touring, (which is mostly because there are only a few rooms complete,) but will be open to scheduled full tours once finished.
